F-Secure Antivirus 2011
Avast Internet Security
Zemana Anti-keylogger
Planned for my New Laptop:
KIS/Avast/ESET
Outpost Firewall
MBAM Pro
SAS Pro
+ others...
I am using VIPRE Antivirus Premium+SUPERAntiSpyware Pro+Mamutu+WinPatrol Plus+Process Lasso Pro (hey, Process Lasso have the ability to suspend a specific program from running). I also still got Avast Internet Security, Panda Cloud AV Pro, Emsisoft AntiMalware, Online Armor Premium++, and Wondershare TimeFreeze 2.0 in my sleeves.
However, sometimes I doubt having them all is indeed useful for me because I always treat my PC carefully, whether I goes offline or online. Up to now, I can see scanning results from VIPRE and SAS have given me a whole bunch of internet cookies only. Nothing strange with my PC behavior too.
