I have had the Avast Premium package plus add-ons BreachGuard, Anti-track, VPN, Driver Updater and Cleanup Premium for several years now And I have only ever had one problem with my pc possibly being infected with something. I say "possibly" because we (a PC Tech & I) aren't able to be sure if it was indeed an infection or just the MS Windows imploding.

Therefore, Avast gets my positive vote as a damn great protection package.
