Last night I went to several unknown websites and my computer got infected by
a virus. Now, my monitor is barely visible and the screen resolution and
color are changing in every minute. Sometimes the screen is even turning
black. I scanned the computer for virus, but the result came out as
negative. The antivirus software couldn't detect any virus at all. I'm not
much of a computer person, so I'm out of my material here. I can't afford to
go to a technechian, so it'll be very helpful if someone could help me out.
Thanks.
