i used to run windows defender, AVG, and spyware terminator together, but i took out spyware terminator because the annoying popups were driving me crazy! so i picked up norton 360 and now i'm running it alongside windows defender and AVG.
i notice that norton has a lot of optimization tools that clean out your temporary files and that defragment your hard disks. formerly i use ccleaner for cleaning purposes and auslogic diskdefrag for my defragmenting.
question: now that norton 360 performs these same functions, would it be safe to take out AVG, ccleaner, and diskdefrag?
BTW: so far no problems with norton 360. running like a dream, no slowdown whatsoever.
