MSE's support for XP has just been extended to July 2015.

used AVG for years and shoved it on any pc i had to take care off, now after some hickups i ended up switching to MSE to try it out (with a different one ofn my main rig) and switched over to it a year back, but after reading this thread im thinking ill switch to something else. i was considering Avast but im sure my mate had terrible problems last i heard.
*sigh*
