4400 - Removal tools for conflicting anti-virus products

http://www.avg.com/us-en/faq.num-4400


The AVG installation package is able to detect conflicting anti-virus products that may prevent some AVG components from functioning correctly. If a conflicting program is detected, it must be uninstalled before installing AVG. Generally, programs can be uninstalled using the standard Windows Add or Remove Programs option. To uninstall the conflicting program, please proceed as follows:

Windows XP

Windows Vista or 7

Windows 8

If you encounter any issues uninstalling a conflicting program, we recommend using a dedicated removal utility or instructions designed specifically for each program:

After using the uninstallation utility or following the removal instructions, restart your computer and run the AVG installation.

Note: If you experience any issues uninstalling a conflicting product, please contact the technical support of the program's vendor.
