Half-a-dozen desktops and several laptops, mostly on XP. Spent some time yesterday removing MSE and installing AVG, Replaced the MS firewall with ZoneAlarm. Malwarebytes still running strong. I have more to do today. Hiho.
Hanging around dodgy websites and other sketchy activities will provide more dangers of invasion no matter what OS you're using.
Switched browsing to Chrome, and I must say it's taking it's own sweet time about learning my habits, but so far it's terribly slow. Might want to check out Firefox.
OK so far, but we'll see what happens long term.
