How to Remove Antivirus?

How to Remove Antivirus?Changing your antivirus product is a non-trivial thing to do. While all the major antivirus products have become better about uninstalling from Add or Remove Programs, many still fail this - either in general terms or in specific cases. Therefore, if changing your Antivirus it's recommended to follow steps below. (Important Note: Run the Uninstall/Remover Utility, if used, in Safe Mode - if possible.)

- Please do not install a new antivirus product while a predecessor product is installed. In some cases, this can cause issues so severe that new installation of the operating system will be required to repair matters. Uninstall the older program using Add or Remove Programs. Reboot. Download and run the suitable removal tool for the older program, if it exists. Reboot again. Now you can install the newer Antivirus product. Reboot again. Be sure to check immediately for new definition file updates.

- If it is too late to uninstall a predecessor Antivirus product, uninstall the oldest first. Reboot. Run the appropriate removal tool, if available. Reboot again. Uninstall the newest next. Reboot again. Run the appropriate removal tool for this Antivirus program as well. Reboot again. Reinstall the newer Antivirus program. Reboot again. Be sure to check immediately for new definition file updates.

- If your Antivirus product is acting poorly, such as not updating or having problems scanning, consider doing a complete refresh installation. Use Add or Remove programs and uninstall it. Reboot. Download and run the suitable Removal Tool. Reboot again. Install the Antivirus product once again, and reboot. Be sure to check immediately for new definition file updates.

- If your computer came with a time-limited "Trial Offer" of any major antivirus product, follow the steps in this Guide before installing its permanent replacement Antivirus product. Use Add or Remove Programs and uninstall the Trial and any of its associated components. Reboot. Download and run the suitable Removal Tool. Reboot again. Install the new Antivirus product you have chosen, and reboot. Be sure to check immediately for new definition file updates.
