I had purchased Avast last month for my desktop, but within a week, my system had crashed, fully and totally unrecoverable. I bought a new desktop, but now I'm weary about moving my license to this PC. I have no proof of what had happened to the machine, I only know that my logon password was not working, even though I could logon with a different device to the same account. Even a system recovery would not work. Would like to have some protection against anything for this PC: MacAfee spreads like wildfire; Norton thinks it knows but why download the same virus defs 15 times in 2 weeks time and still not be up to date; AVG .... jury still out; Avast, bought license and a week later system failure. Maybe it just my luck, but I'm tired install/reinstall/uninstall/try something else cycle.
