I would be grateful for some advice
. I have managed to get a virus on my computer that is posing as the Security Centre. This isnt the problem as I have found lots of advice telling me how to resolve and get rid of it. The problem is the virus is totally blocking all my system access. It lets me open sounds info, word documents etc, but if i want to go to anything that involves systems it wont open. I thought therefore the easiest way was just to reinstall the whole system but i have encoutered a problem. I have a winfast system and it appears that the manufacturers recently included a password on the bios during an install. I cannot find this password anywhere. Can anyone suggest any solution to me, someone who is not very technical, as I know you guys seem to know everything about anything.
