hi tan pang,

thanks for your prompt response

i use mcafee site advisor for my internet security. Kaspersky is the only anti virus I have.

i have been trying to scan my backup ie e drive and c drive...always forced aka sudden shut down ( thermal overheating )...for the past three days. I cant seem to scan my pc properly

at the moment i am using anti bytes malware to scan my pc in safe mode

Any advice, please cause I am really a newbie and most of the time, I format my pc if there's problem.
