June 4th, 2012 22 comments

With over 140.000 active beta testers of version 1.9.1 (!!!) and after a long wait Panda Cloud Antivirus Beta 1.9.2 is finally here. This new beta release incorporates not only a lot of bug fixes as reported by the large beta community but also new features such as a new firewall platform and intrusion detection system. This new beta version includes better malware disinfection capabilities and even lower impact on system performance. Last but not least Panda Cloud Antivirus Beta 1.9.2 is compatible with the recently released Windows 8 Release Preview.

Other than that the upgrade is completely transparent.

Some of the most notable changes implemented for 1.9.2 are the following:

  • New firewall platform for Windows Vista, Windows 7 and Windows 8.
  • Intrusion Detection System protection against network attacks.
  • Ability to adapt firewall behaviour by zones.
  • Registration of the firewall component in the Windows Security Center.

  • Improved detection of in-memory malware.
  • Improved disinfection of packed/compressed malware.
  • Improved quarantine management.
  • Process monitor without the URL monitoring.
  • Activity monitor in the main interface window.
  • Last detection show in the main interface window.
  • Added advanced configuration to enable/disable detection of potentially unwanted programs.

  • Improved integration with the Windows Security Center for the antivirus component.
  • Improved integration with Collective Intelligence of unknown and new malware samples.
  • Performance improvement to lower system impact when treating files within Explorer and Recycle Bin.

If you don’t want to wait for the automatic upgrade you can manually install Panda Cloud Antivirus 1.9.2 by downloading it directly from As always you can provide feedback, send us suggestions and discuss with our QA Department about this beta version in our Beta Support Forum.

It is impressive that over 140.000 beta testers have helped us improve the product so much over the last year. Again our most sincere “THANK YOU” to all our beta users and hope you enjoy this new 1.9.2. We promise this new beta won’t be as long as the 1.9.1 beta and very soon we will all be able to enjoy the final Panda Cloud Antivirus 2.0 release :)

Panda Cloud Antivirus & Firewall Beta (1.9.1)

August 17th, 2011 50 comments

Finally the new Panda Cloud Antivirus beta is here, getting us closer and closer to the expected Panda Cloud Antivirus 2.0 release. Version 1.9.1 incorporates a full fledged firewall with application and system rules. This new firewall and its settings is available from a new tab off the main GUI.

The full firewall included in this beta version is a smart community-based firewall which will automatically assign inbound and outbound communication privileges to processes. The automatic assignment is performed depending on its risk assessment as well as the direction of the communication which is being initiated. So if an OUTBOUND connection is being made by a Secure or Low Risk process, the process is allowed to communicate automatically. Alternatively if a process is deemed riskier, a prompt will ask the user to choose whether to allow or block the communication. A similar although stricter approach is used for INBOUND connections.

The risk assessment of executed processes is shown in the Process Monitor window of the main GUI as shown in the first picture of this blog post. This is calculated automatically based on many different conditions, such as safe lists, digital signatures, telemetry and prevalence, automated analysis of processes, etc.

However users can also manually manage the firewall rules by adding new ones, editing, deleting, importing and exporting rules and prioritizing certain rules over others. This is easily done from the Program Control window under the firewall tab of the main GUI as shown in the next picture.

Finally there’s also a lot of improvements in the antivirus part of the program, as always targeted at making Panda Cloud Antivirus even lighter and faster, as well as a usual batch of bug fixes. The full changelog can be seen below.

* Firewall application rules for programs which can access the network or Internet.
* Firewall system rules for all programs.
* Firewall rules priorities.
* Automatic management of rules based on analysis and Process Monitor.
* Notifications of connection attempts and ability to create rules to allow or deny connection.
* Ability to import and export rules.
* Notifications in the event report of connection attempts which have deny rules.
* Additional types of cloud-queries for suspicious malware.
* Optimized Behavioral Analysis engine, both On-Demand and On-Access
* Improved cache of already scanned items to increase scan speeds and lower performance impact.
* Change GUI icons for Recycle Bin and Firewall.
* Added shield exclusions for Panda Cloud Office Protection processes.
* Signed drivers for installation and upgrade.
* Updated Panda Security Toolbar to with Firefox 5.0 compatibility.
* Fixed behavioral blocking engine FP with OpenOffice.
* Fixed wrong translations on the context menu “Scan with Panda Cloud Antivirus” entry.
* Fixed incorrect message “incompatible AV” in installer.
* Fixed problems displaying the installer with non-default display settings.
* Fixed BSOD with NNSHttp.
* Fixed BSOD with NNSPrv.sys
* Fixed problems with lost connectivity after install.
* Fixed error 513 with diagnostic tool NetDiag.
* Fixed problem analyzing some compressed files inside compressed archive.
* Fixed problem with Panda Cloud Antivirus Service stability.


Again thanks to the more than 16.000 beta testers so far who are helping us create a really stable Panda Cloud Antivirus 2.0. Please test this new beta version as much as possible and don’t forget to report back.

Panda Cloud Antivirus Beta 1.9

April 29th, 2011 25 comments

Today is a very special day for us at Panda Security for two reasons. First because today marks the two-year anniversary since we released the first beta of Panda Cloud Antivirus, the first free antivirus from the cloud. To celebrate this, we’re releasing another beta version today, Panda Cloud Antivirus Beta 1.9.

The objective of this beta version is to test the interception of networking traffic in order to build cloud-based firewall functionalities in future versions. In this beta the networking interception is applied to both HTTP and POP3 traffic. Even though the program incorporates a Process Monitor which keeps track of HTTP web traffic requests on a per process basis and allows for per-process blocking, no traditional firewall functionality is provided in the beta, only interception.

In order to promote thorough testing of this version, we are giving away 10 $100 gift certificates to the most active beta testers who report bugs in the Panda Cloud Antivirus Beta Support Forum. The winners of the gift certificates will be selected at the close of the promotion by the Support Forum Moderators amongst the users with the most amount of new (unknown at the time of posting) bug reports. Note that the beta may still be ongoing after be promotion ends on August 1st, 2011. In addition there will be PRO license codes given away to other active beta testers as well.

New Features
- Process Monitor functionality and traffic history reporting.
- Ability to block a process by sending it to Recycle Bin.
- Blocked processes can be restored from the Recycle Bin.
- Ability to disable/enable BackgroundScan after signature cache synchronization.
- Ability to exclude file extensions from the on-access scanner.
- Exclusion of Potentially Unwanted Programs (PUP) detections.
- New graphical installer. Logs are kept under %TEMP%\StubInstaller.log.
- New Toolbar without ID Protect & Shopping and with Toolbar Cleaner.

Beta3 Preview – Windows 7 & 64bit Support

August 27th, 2009 48 comments

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 or send your comments to this blog post.

The download link is the following:
EDIT: changed link to point to a more reliable server.

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.

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_MACHINESOFTWAREWow6432NodePanda SecurityPanda Service Host]

Disabling BackgroundScan:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREWow6432NodePanda SecurityPanda Service Host]

Enabling Exceptions:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREWow6432NodePanda SecurityPanda Service HostExceptions]

Error Code 1: Catching Exceptions and Creating Minidumps

July 27th, 2009 2 comments

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]

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:
Username: betatester
Password: d8PvVVdTQzWv

Don’t forget to drop us a note at 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

July 22nd, 2009 2 comments

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 (

Notification popup of Beta period

July 22nd, 2009 9 comments

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

July 3rd, 2009 16 comments

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

June 30th, 2009 87 comments


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).


1- Uninstall the Beta1 from Control Panel, Add/Remove Programs. Reboot.
2- Download the Beta2 from
3- Install the Beta2.


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.




icon-malware     icon-suspicious

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.
