Avast! Free Antivirus.

This is our new flagship product and replaces Avast Home Edition (we changed the name to emphasize the product is free). We focus this product on users that use the internet for web browsing and email. If that is what you do on the internet, this is the product you need. We are very proud of this product and we stack it up against anyone else’s paid antivirus—in fact, we have recently started submitting this product in lieu of our paid products to all of the industry standard tests. Virus Bulletin, one of the most respected journals, recently called this product “….nothing short of a miracle” (see separate blog post). Google selected this product for incorporation in many of their Google Packs. You can download this product here

Avast! Internet Security.

This is our brand-new product and is focused on users that do on-line banking or shopping or that have sensitive data on their computer. We believe that these users need some extra layers of protection and developed this product to provide three more layers. This product takes the free antivirus and adds a 2-way silent firewall, a sandbox, and anti-spam. The firewall ensures that only trusted applications are able to receive or send data across the internet. The sandbox provides a means of executing your browser (or any other application) in a protected environment—thus even if you get infected, the infection does not leave the sandbox and does not harm your computer. And the anti-spam helps you get rid of all that irritating email you receive every day. And, we have made this product attractive to consumer users—a single license can be used on 3 computers in your household. This link will take you to the product and download page

Avast! Pro Antivirus

This is the update to the old Professional Edition. We focus this product on individuals that want to customize their security and on businesses. It is the same as Internet Security but without the firewall or anti-spam. This allows world-class security using your own personal choice of firewall and anti-spam. Here is how to get this product

Windows 7 is now hit the retails stores and PC vendors are also offering Windows 7 to their customers. We can say that Windows 7 is one of the most secure operating system by Microsoft but it also need an antivirus program for protecting your computer from Malwares, viruses and from other malicious software programs.Here are antivirus programs that have earned the Compatible with Windows 7 logo.

Windows XP SP3 users reported that CA Antivirus falsely identified Windows XP system files and placing them in quarantine. Windows XP home office and small business users have reported the following files were affected.

c:\windows\system32\net.exe
c:\windows\system32\netsh.exe
c:\windows\system32\reg.exe

The CA advisory reads:

CA Internet Security Suite users should restore affected files from quarantine using the GUI. CA Threat Manager customers should search local hard drives for files with the extension .AVB and manually rename to their original file extension by removing the appended text on the original file name.

This is a false positive due to CA Anti-Virus Update # 6604 and has been corrected with CA Anti-Virus Update # 6606 or later.

Please update the CA Internet Security Suite software to avoid getting these alerts again.

Once the product updates are over you would need to restore quarantined items by following the article below:

View/ Delete/ Restore Files Quarantined by CA Anti-Virus

To keep your system working fine we all do some regular tasks including scan for virus, backup and create restore points.(all these activities are related to windows operating system). Before performing our regular system if we if follow these simple steps then we can remove more virus and other harmful files from our computer.

Before starting the system scan turn off or disable the System Restore, in Microsoft Windows xp and Microsoft Windows ME the folder _Restore is protected by default.Antivirus cannot remove virus or any malicious files inside _Restore folder. Windows prevents outside programs,including antivirus programs, from modifying System Restore. The System Restore feature is not designed to detect or scan for virus infections or virus activity.

Update your antivirus software with latest virus definitions. All antivirus software come with the auto update. its better to set auto update enable instead of manual update.

Backup system registry before editing the system registry.System registry contains information and settings for all the hardware, operating system software, most non-operating system software, users, preferences of the PC, etc. Any wrong changes will lead you to more problems.

Restart your system in safe mode and perform the full system scan. When windows is running in safe mode it has reduced functionality but the task of isolating the problems is easy because most of the core services are not running or disabled.After the successful full system virus scan delete all these registry values from the system registry
