@Admin,Well yes I am really being cynical coz I am very worried ever since the last attack on my PC 2 weeks back. In simple terms, it was not like as if my PC just had a fever or a cough-n-cold, but was like as if my PC had cancer....Yes, so badly infected my computer was. Anyways, at present only Microsift Sec Ess[updated] is installed. By the way, MS Sec Ess and Win Defender does not get installed together.:wall: You can have only 1 app at a time. Anyways, I am with MS Sec Ess at present since it has both an AV & AS.Thanks Piyush for replying. I will review Comodo as well.@Zeo,A big thanks to you for helping me out with the links. Avast Prof Ed looks promising but its a paid one, so I am not going for it. Now I have to choose between Avast Free Ed and AVG Free Ed. By the way, I think Avast does not have an inbuilt Anti-Spyware...Does it ? And does it hog the system ?
