Antivirus and internet security software are notorious for having poor uninstallers which often fail to do their job. In fact all the major security vendors offer separate tools to uninstall their applications. It is ironic that antivirus applications are often harder to remove than a malware.
If you are frustrated with the shabby and incompetent uninstallers offered by various antivirus and internet security software vendors then you will love AppRemover. It is a freeware utility which can uninstall antivirus software as well as clean up a failed uninstall. Currently AppRemover supports products from all the major security vendors including Alwil (avast!), AVG, Avira (AntiVir), ESET (NOD32), F-Secure, Kaspersky, McAfee, Panda, PC Tools, Sophos, Symantec (Norton) and Trend Micro (PC-Cillin). You can view the full list of supported applications here.
Using AppRemover is extremely simple. It is a portable software (doesn’t require installation) and can be run directly from an USB drive. AppRemover can uninstall security applications as well as clean up failed uninstallation attempts. It automatically scans your computer and detects all installed security products. All you need to do is select the application you would like to get rid of and AppRemover will take care of the rest.
