Beta3 Preview – Windows 7 & 64bit Support

     
We have been circulating a limited Preview Release of Beta3 which supports Vista 64bit and Windows 7 (32 and 64bit). This Beta3 Preview only has additional platform support. No other functionality which is currently being developed for Beta3 is included yet in this Preview Release.

Basically we’re interested in getting as much feedback from the 64bit and Windows 7 community as possible. If you’re one of these guys or gals, we want to hear from you. Please send all feedback regarding this Preview Release to beta@pandasecurity.com or send your comments to this blog post.

Downloading
The download link is the following:
CloudAntivirus-Beta3-0.08.83-Preview.exe
EDIT: changed link to point to a more reliable server.

Installing
If you have a previous version of Panda Cloud Antivirus, you’ll need to manually uninstall that first, reboot and then install the Beta3 Preview.
Note: The Beta3 Preview can also be installed on XP/Vista 32bits, even though we’ve not tested it in these platoforms.

Workarounds
Remember that under x64 the registry entries for the different workarounds mentioned in this blog are different. They are the following:

Activating advanced logging:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Panda Security\Panda Service Host]
"tracePath"="C:\\Logs_CloudAV"
"traceEnabled"="1"

Disabling BackgroundScan:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Panda Security\Panda Service Host]
"BackgroundDisabled"="-"

Enabling Exceptions:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Panda Security\Panda Service Host\Exceptions]
"CreateMiniDump"=dword:00000001
"ToMessageBox"=dword:00000001

Error Code 1: Catching Exceptions and Creating Minidumps

 
If you’re having any type of problem with Panda Cloud Antivirus (a recent one we’re getting is the Error Code 1 while scanning) you can help us troubleshoot it by enabling exceptions and having Panda Cloud Antivirus create minidumps when it runs into a problem.

You can enable exceptions easily by creating the following registry key:
   Windows Registry Editor Version 5.00
   [HKEY_LOCAL_MACHINESOFTWAREPanda SecurityPanda Service HostExceptions]
   "CreateMiniDump"=dword:00000001
   "ToMessageBox"=dword:00000001

For those less familiar with manipulating the Windows Registry you can simply download and execute the following Exceptions.reg file which will automatically make the change in the Registry for you:
Enable Exceptions

Once enabled, any exception caught will be shown to you in popup windows similar to the following ones:

If this happens, you can find the minidump in the following locations:

• XP: c:documents and settingsall usersProgram datapanda securitypanda cloud antivirus
• Vista: c:program datapanda securitypanda cloud antivirus

Simply compress (in a ZIP or similar) the minidump and send it to us. We have enabled an FTP account where these can be uploaded to.
FTP Server: 212.8.79.111
Username: betatester
Password: d8PvVVdTQzWv

Don’t forget to drop us a note at http://www.cloudantivirus.com/forum if you do upload a minidump so we can provide you with an answer or fix after we analyze your upload.

Again thanks to all that are helping us improve Panda Cloud Antivirus !

 

CloudAV Standalone Uninstaller

Some users upgrading from Beta1 to Beta2 version have come across problems during the uninstall/reinstall upgrade procedure. In order to try to make things easier on users we have created an uninstaller standalone application for Panda Cloud Antivirus.

IMPORTANT: only use this generic uninstaller on PCs with Panda Cloud Antivirus. If this uninstaller is executed on PCs with other Panda products (Panda Antivirus Pro, Panda Internet Security, etc.) it will have negative effects and will leave the PC in an unstable state.

Simply download and execute the uninstaller in the following ZIP file:
Download Cloud Antivirus Uninstaller

If you’re still having problems with an uninstall procedure and would like the manual instructions feel free to contact us at the Technical Support Forum (http://www.cloudantivirus.com/forum).

Notification popup of Beta period

Some Beta1 users have misunderstood the popup message that was recently shown by Panda Cloud Antivirus, announcing the availability of the Beta2 version.

The feedback we received is that some users thought the software was going to stop being free. I wanted to post this to clarify any confusions that might have been created by this notification.

This notification is merely announcing the availability of the Beta2 version. Some considerations to take into account during the beta period:

• As soon as a new Beta version is announced (Beta2, Beta3, etc.) the previous Beta version will stop connecting to Collective Intelligence and updating its cache.
• Users can of course download the new Beta version for free.
• After the Beta period is over and Panda Cloud Antivirus version 1.0 is released it will continue being free without any loss of functionality whatsoever.

Sorry if this notification has caused any confusion.

Cloud Antivirus Beta2 Under Windows 7

We’ve received quite a lot of reports lately from people who have managed to install Panda Cloud Antivirus Beta2 under Windows 7 based on a post from the DownloadSquad.

Basically the method used to install Cloud Antivirus Beta2 under Windows 7 consists of uncompressing the CloudAntivirus.exe installer file using WinRAR, 7-zip or any other capable un-compressor and setting the compatibility mode of the SETUP.EXE to Vista.

You may then run the installer by double-clicking on SETUP.EXE and this will install Cloud Antivirus Beta2 happily on a Windows 7 system.

During some quick testing both the on-access and the on-demand scanner seem to work normally.

However please be advised that Cloud Antivirus Beta2 has not yet been certified by our QA team and therefore is not fully Windows 7 compatible. We’re still working on Beta3 which will be fully compatible on both 32 and 64 bits Windows 7.

Cloud Antivirus Beta2 Released

   

Thanks to the millions who have downloaded and installed Panda Cloud Antivirus Beta1 (0.08.80) and sent feedback to help us improve the product before its final release. Today we’re releasing Panda Cloud Antivirus Beta2 (0.08.81).

   

INSTALLATION INSTRUCTIONS
1- Uninstall the Beta1 from Control Panel, Add/Remove Programs. Reboot.
2- Download the Beta2 from http://www.cloudantivirus.com.
3- Install the Beta2.

   

BETA2 IMPROVEMENTS
We focused Beta2 on fixing the most important detection & disinfection aspects per feedback from the community. The following is a list of items that are either new or fixed in Beta2. If you have any doubts about any of them feel free to post your question as a comment.

New – “Undo” Option for Recycle Bin
Some users complained about the effect of the automated deletion of known malware. In some cases where users want these samples to not be deleted and/or in the case of false positives, there was no option to recover these files. A new option has been added with Beta2 to the Recycle Bin so users can recover deleted detections for a period of 3 days (configurable by CI). During this time period file icons will be changed to show that the file is quarantined in the Recycle Bin. NOTE: this does not apply to “disinfected” files, only to “deleted” files.

     

New – Synchronous Real-Time Cloud-Scan
Under some circumstances files being executed (directly from Internet download, from a read-only network share, etc.) were checked asynchronously against the cloud after the file was loaded into memory. This resulted in detection+disinfection actions to be taken after infection. With Beta2 we changed this behaviour to block the execution until a response has been received by Collective Intelligence. In the event that it is malware, the file will be deleted prior to allowing it to execute.

New – Latency & Response Control of the Cloud-Scanner
We deployed 10 sensors throughout America, Europe and Asia and have detected that 98.41% of the Collective Intelligence queries are responded to within 3 seconds. However, in the remaining cases there is not a control mechanism and if the response is not timely (because of connectivity issues, latency, proxy delays, etc.) then the program would be allowed to execute prior to receiving the response from Collective Intelligence. With the new response control mechanism, programs executing which take longer than 6 seconds to receive an answer from Collective Intelligence are put “on hold” for a second timeout period of 30 seconds after which the program is unblocked and allowed to execute (although it will continue being scanned asynchronously).

Fixed – Slow Scans
Right after installation Panda Cloud Antivirus launches a BackgroundScan of the entire PC to ensure it is clean. Some users reported that launching an On-Demand scan of the entire PC right after install slowed down the PC and/or caused the scan to take a long time. This bug was due to both the BackgroundScan and OnDemandScan running simultaneously. With Beta2 this is fixed by having the BackgroundScan automatically pause in case it detects an OnDemandScan being launched. Once the OnDemandScan is finished, the BackgroundScan will resumen where it left off.

Fixed – Recycle Bin Unblock Functionality
Under some circumstances and with certain types of malware, some users reported that unblocking a suspicious/potentially unwanted malware that was sent to the Recycle Bin, resulted in it being continuously detected over and over again. This has been fixed in Beta2.

Other Fixes

Correct integration with Windows Security Center.

Crash during full PC scan.

Disinfection bug under Vista needing a reboot.

Continuous “reboot needed” for disinfection bug.

PSANHost.exe service entered unstable state after cancelling a running scan.

“Code 1 Error” during full PC scan.

Grayware (PUP) found on network shares was not sent to Recycle Bin.

Grayware could be deleted from folders where the user did not have write access.

Various system crashes fixed.

Other fixes during detection, uninstallation, and scanning.

By the way, we’ll still release a Beta3 version prior to final release of Version 1.0. For Beta3 we’re already working on new platforms (Windows7, 64bits), improved features, a new website, a Collective Intelligence real-time encyclopedia and some additional things. Expect the Beta3 to be released around September.

    

Frequently Asked Questions

 

We’ve been getting a lot of positive feedback from the community regarding Cloud Antivirus. Thanks to all for downloading, testing, and using it. Of course there are many questions that are being answered through this blog and via comments, but as not all users read through the comments, I thought I’d compile a list of the most important and most common questions as well as answers. The list is comments/questions is the following (scroll down for the answers):

• Why isn’t there a 64bit and Windows7 version?
• Will Panda Cloud Antivirus continue being FREE after the beta is over?
• Do I need to run a different antivirus at the same time as Cloud Antivirus?
• Am I still protected when I’m not connected to the Internet?
• After installing Cloud Antivirus I scanned my PC and it took a really long time. What’s up?
• Are my files being sent to the cloud for scanning?
• What exactly is sent to the cloud?
• Cloud Antivirus detected a Trojan and deleted it. How can I get it back?
• Why can’t I choose delete/block/ignore when it detects a Trojan?
• Can I run Cloud Antivirus alongside my Norton360/AVG/Etc.?
• Scan stuck at x%.
• I have 2 monitors and Cloud Antivirus always appears right in the middle of both.
• Since I installed Cloud Antivirus my system has *really* slowed down to a crawl.
• I’m having problems downloading the Cloud Antivirus installation program.

 

 

Why isn’t there a 64bit and Windows7 version?

Basically we wanted to get Cloud Antivirus out there and tested as soon as possible to validate the new philosophy and protection model. Supporting additional configurations was less of a priority than seeing if the model is truly valid or not. However we’re seeing that by popular demand this is the #1 request we’re getting so we’ll re-think our priorities and try to release these builds as soon as possible.

 

Will Panda Cloud Antivirus continue being FREE after the beta is over?

YES. Absolutely. 100%. Free.

 

Do I need to run a different antivirus at the same time as Cloud Antivirus?

No. Cloud Antivirus provides all the protection you need from viruses, malware, etc. Also it is not recommended to run 2 different AV engines at the same time as they can conflict with each other.

 

Am I still protected when I’m not connected to the Internet?

Yes, you do not need to be connected to the Internet all the time in order to be protected. Cloud Antivirus stores a “local cache copy” of Collective Intelligence for offline operation. As soon as you disconnect, Cloud Antivirus still works in the background, checking every file against its local cache of detections. This local cache includes, amongst other things, detection for all malware files which are currently in circulation and affecting users.

After installing Cloud Antivirus I scanned my PC and it took a really long time. What’s up?

If you run an on-demand scan of your entire system right after installing Cloud Antivirus you will experience this slowness because both the initial Background Scan and the on-demand scan are running simultaneously. Panda Cloud Antivirus runs a Background Scan after installation. During this Background Scan Cloud Antivirus does a review of the entire PC by scanning it and by filling up its goodware cache (checking known good files against the cloud) in order to optimize future scans. Simply allow Cloud Antivirus to finish its Background Scan before launching a full system scan. If you are experiencing problems after that, please export your Windows Event Log for Cloud Antivirus (My PC, Manage, Event Viewer, Nano, right-click & Save as) and send it to us at beta@pandasecurity.com.  

 

Are my files being sent to the cloud for scanning?

No. Absolutely no files and no personal information is sent to the cloud. Also only PE files (.EXE, .COM, etc.) are checked against the cloud. Non-PE files such as pictures, documents, etc are not scanned from the cloud.

 

What exactly is sent to the cloud?

For any PE file that is checked against the cloud, we create multiple cryptographic hashes. Amongst them is what we call a “reverse signature” of the file. This reverse signature is able to identify multiple similar files. The response from the cloud can be “malware”, “goodware” or “unknown”. Also we send “behavioral traits” of files to be scanned heuristically remotely by the cloud. These are basically properties and characteristics of each file. In summary, no content and no personal information is ever sent to the cloud.

 

Cloud Antivirus detected a Trojan and deleted it. How can I get it back?

Cloud Antivirus is pre-configured to automatically delete malicious files. However suspicious files and certain types of grayware (hacking tools, potentially unwanted programs, etc.) are not deleted automatically and sent to the Recycle Bin (quarantine). To access the Recycle Bin, click on the folded bottom right corner of the Cloud Antivirus program. From there you can unblock detected files and get access to them again. Keep in mind that, once unblocked, these will not be detected again by Cloud Antivirus. However if the file that was detected is a true malicious file such as a Trojan, it will be deleted automatically and there’s no way to get it back (after all, you’re installing Cloud Antivirus to get rid of malware, right?).

 

Why can’t I choose delete/block/ignore when it detects a Trojan?

As an antivirus program, the main thing that users ask for from us is that we detect and get rid of malicious files without bothering them. This is exactly what Cloud Antivirus does, keeping everything as simple and straightforward as possible. This is what we’re trying to do with the new protection model of Cloud Antivirus, to manage all these decisions for end users automatically. However we are getting some feedback from advanced users to have this functionality included. We’re thinking about how to approach this but one way would be to activate an “advanced mode” and while in that mode maintain an encrypted copy of every detected file in the Recycle Bin (at least for x amount of max time) that can be recovered if needed. Comments about this approach are welcomed.

 

Can I run Cloud Antivirus alongside my Norton360/AVG/Etc.?

No you can’t, just as you can’t (or shouldn’t) run two or more different antivirus programs at the same time. The Cloud Antivirus installer identifies a large number of AV programs and will stop the installation if it detects one running. However there are reports of some users that have been able to install Cloud Antivirus running at the same time as lesser known AV programs such as Spyware Doctor Antivirus. In these cases you might experience slowness or slugginesh of the Operating System. To resolve this issue simply uninstall one of the two AV programs.

 

Scan stuck at x%.

Issue 1: This is a bug of the interface transparency effect. It’s not really a bug with the scan itself; rather it’s a bug on the interface painting actions. It occurs when, during the scan, the screensaver kicks in or the user session is closed. After coming back to the scan window, the impression is that the scan is stuck. However if you click on the scan window and drag it you can see that the scan is finished or still progressing.
Issue 2: We have had some reports of stuck scans which are not due to the interface transparency effect. If you are experiencing this problem, please export your Windows Event Log for Cloud Antivirus (My PC, Manage, Event Viewer, Nano, right-click & Save as) and send it to us at beta@pandasecurity.com.

 

I have 2 monitors and Cloud Antivirus always appears right in the middle of both.

Yes this is a reported and known bug. We’ll fix it as soon as possible.

 

Since I installed Cloud Antivirus my system has *really* slowed down to a crawl.

See the FAQ above about running Cloud Antivirus in parallel with another AV program. If this is not the case and you still experience slowness of the Operating System in general, please contact beta@pandasecurity.com and send us the details of your configuration.

 

I’m having problems downloading the Cloud Antivirus installation program.

Delete all temporary file from your browser and try downloading again from www.cloudantivirus.com.

 

Known Issues

 

The following issues have been detected by our beta testers which should be taken into consideration.

Installation / Uninstallation Issues

• During an incomplete uninstall, after reboot, the uninstall process cannot be finished. SOLUTION: We’re creating an uninstaller, but in the meantime please send us the log that is shown in the warning message.
• Cannot install after an incomplete install. SOLUTION: We’re creating an uninstaller, but in the meantime please send us the log that is shown in the warning message.
• Error while re-installing as a file cache is in use. SOLUTION: click “Retry” and allow the installation process to finish. It will complete successfully in spite of the warning message.

 

Application Issues

• Report takes a long time to show over 10.000 detections. WORKAROUND: as the Panda Cloud Antivirus Log is saved in the Windows Event Viewer, delete the corresponding Event Viewer Log before launching an on-demand scan over many files to help improve the responsiveness of the report viewer.
• The Recycle Bin (quarantine) takes a long time to show when there are many items in it.
• In the Event Report the name of the detected malware is shown as “Not available”. This means that either Internet connectivity was lost during the synchronization with Collective Intelligence or the malware naming webservice is not responding correctly.

 

Detection & Disinfection Issues

• Boot scan not performing correctly.
• Infected PE files which are not file-infectors and which are downloaded via HTTP, the product prompts for reboot disinfection even though it’s not really necessary.
• In infected compressed or packed containers which hold multiple elements, where at least one is infected, the product prompts for reboot disinfection even though it’s not really necessary.
• In some cases after disinfecting a file-infector virus the product notifies as “not neutralized” even though it was disinfected correctly and vice versa (in the case where the virus is in memory or the user does not have write-access to the directory respectively).
• Does not intercept nested Office file formats.
• When launching and on-demand scan over a very large number of malware samples the scan may be stuck at 99% of completion. SOLUTION: Disable BackgroundScan (will post details soon on how to do this).

 

As always we appreciate and welcome testing feedback so please keep them coming at beta@pandasecurity.com or in the form of comments on this blog.

Welcome to the Panda Cloud Antivirus Beta

Today we’re releasing the public beta of Panda Cloud Antivirus, which is the first free cloud-based antivirus thin-client. It consists of a lightweight antivirus agent that is connected in real-time to PandaLabs’ Collective Intelligence servers to protect faster against the newest malware variants while barely impacting PC performance.

Thanks to Panda Security’s Collective Intelligence malware and goodware online database, Panda Cloud Antivirus detects more malware than traditional signature-based solutions which take longer to detect the most recent, and therefore most dangerous, variants.

With Panda Cloud Antivirus we introduce a new protection model based on a thin-client agent & server architecture which services malware protection as opposed to locally installed products. By combining local detection technologies with cloud-scanning capabilities and applying non-intrusive interception techniques on the client architecture, Panda Cloud Antivirus provides some of the best protection with a lightweight antivirus thin-client agent that barely consumes any PC resources.

Our objective is to release a solution based on this new protection model which helps solve the malware problem by improving user experience. After almost 20 years fighting viruses and malware we have changed our mentality at Panda. We would like to open ourselves to you and show you how we pretend to do things. In this blog we’ll explain in depth how this new model works in order to help improve it with you, our users.

As for the beta objectives, we’re interested in collecting information from betatesters, evaluators, testers, etc. that can provide feedback on how the new protection model works under different scenarios in order to help us verify it as a valid model and to adapt it to real life.

Of course keep in mind that this is still beta code and as such we continue improving and tuning both the cloud architecture and detection techniques as well as the agent architecture, specially now during the initial phases. We’ll progressively release new versions which you’ll be able to use as we improve the overall protection and user experience.

Feel free to download Panda Cloud Antivirus if you haven’t done so yet. For suggestions please use the form located at www.cloudantivirus.com and for submitting bugs please use beta@pandasecurity.com.
