Installation

Remove Other Security Software and Incompatible Software

Many installation issues are caused by having incompatible software on your computer. Please make sure you have removed any previous security software, such as other Anti-Virus, Anti-Spyware, Internet Security, or standalone Firewall applications.

Kaspersky versions 2009 and 7.0 do not need to be removed prior to installing Kaspersky 2010. Even if your previous security software is not in the official list of incompatible software, removing it prior to installing Kaspersky is recommended.

Uninstall using the Windows Control Panel

If you have Windows Vista, go to Start > Control Panel > Programs > Programs and Features. Click the program to remove, and then click the Uninstall button above the list. If you have Windows XP, go to Start > Control Panel > Add or Remove Programs. Click on the program to remove, and then click on the Remove button to the right.

Remove Incompatible Software

If the normal removal process still leaves behind leftovers of an incompatible program, running the removal tool for that program should resolve the issue.

If you had a Norton or Symantec previously:

Run the Norton Removal Tool, and reboot. For specific instructions, visit Symantec.com.

Save the Norton Removal Tool to your Desktop prior to running it. If you have Windows Vista, please right-click on the Norton Removal Tool file and choose Run as administrator. You may get a one-time pop-up from Norton after rebooting. This is normal, just close the window.

If you had McAfee previously:

Run the McAfee Consumer Products Removal Tool, and reboot. For specific instructions, visit McAfee.com.

Save the McAfee MCPR Tool to your Desktop prior to running it. If you have Windows Vista, please right-click on the MCPR file and choose Run as administrator.

If you had AVG previously:

Run our special Kaspersky Kleaner for AVG, and reboot. For specific instructions, visit our AVG Removal article.

If you have Alwil Avast! previously:

Run the Avast Software Clear Tool, and reboot. For specific instructions, visit Avast.com.

Save the Avast Software Clear Tool to your Desktop prior to running it. If you have Windows Vista, please right-click on the Avast Software Clear Tool file and choose Run as administrator.

If you had Trend Micro previously:

Run the Trend Micro Diagnostic Toolkit for your version of Windows. Right-click on Computer and go to properties, then look for the System type line.

Trend Micro Diagnostic Toolkit for 32-bit Windows systems.
Trend Micro Diagnostic Toolkit for 64-bit Windows Vista systems. Windows XP x64 is not supported.
For specific instructions for both versions, visit TrendMicro.com.

If you had BitDefender previously:

Run the BitDefender Uninstall Tool for your version of Windows. Right-click on Computer and go to properties, then look for the System type line.

BitDefender Uninstall Tool for 32-bit Windows systems.
BitDefender Uninstall Tool for 64-bit Windows systems.
For specific instructions for both versions, visit BitDefender.com.

If you had F-Secure previously:

Run the F-Secure Uninstallation Tool, and reboot. For specific instructions, visit F-Secure.com.

If you had another anti-virus or security program previously:

Avira AntiVir Removal Tool
Microsoft OneCare CleanUp
Webroot Cleanup

Even after running the removal tool, the install process still says I have incompatible software:

If you are sure that the product being detected by Kaspersky is not on the computer, you can skip the check for incompatible software during installation:
Skip Product Check for Kaspersky 2010.
Skip Product Check for Kaspersky 2009 and Kaspersky Security for Ultra Portables.

If you have Windows Vista and are having trouble when installing from the CD:

The Vista security model called User Account Control may be limiting the installation's full access to setup Kaspersky.

In the Start Menu, open Computer.
Right-click on the CD/DVD drive that has the install CD in it and click on Explore.
Right-click on kis2009 or kav2009 and select Run as administrator.

If you get an error saying "This is not a valid win 32 application" or an NSIS error:

This error will occur if the file did not download completely from the web link and you try to run it. To resolve, simply download the file again.

If you experience an error message saying "You must restart your computer before proceeding with the installation,"

There may be traces of an older Kaspersky Lab product in your registry. Please try these steps: http://www.kaspersky.com/support/kolt?eid=207694096
