Hey guys!! I dont know where this virus came from in my pc and now it has broken up my pc like anything..It always hangs up, some or the other pop up windows are coming up..I have no choice left but to get it formatted. Now when I'll install it afresh I need a good antivirus software that keeps those viruses away.. Which antivirus you all think i should go for? I have thought of buying this Norton Antivirus 2008 (3 user pack). I am getting it for £30 . Is it worth buying?? Any suggestions would really be appreciated..Thanks in advance..
