The default way to uninstall an antivirus program is through the “Programs and Features” (Add/Remove Programs) options in the Windows Control Panel. But sometimes, using this method, we face problems during the uninstallation process, for example, the system crashes or the uninstallation process does not complete successfully.. When this happens, the only way to remove the antivirus software is to use the appropriate antivirus removal utility from the antivirus software manufacturer.
In the list below, you will find the appropriate uninstall utility to completely remove and uninstall your antivirus product from your system. I hope you find this list useful.
