I have a laptop pc Pentium IV 2.2 Ghz cannot accept anti-virus software. Everytime I install a new anti-virus, it always disabled automatically for no reason I could’nt figure out. I have tried AVAST 4.8 AVG, KASPERSKY and ESETNOD32 but all of this are disabled by my pc. I have tried reformatting my hard disk already but the problem persist after a couple of days. I think I have done everything to solve the problem but I failed to get rid of this problem. Does anyone knows the reason why my pc always disable every anti-virus that I installed?
