There's a freind that got a virus on his laptop and screen went blank at some point.Since then computer is responding late,mouse pointer moves laggy,and when he tried to install both esset smart security and nod32 antivirus at some point a fail dialogue popped and said something about access to the path directory of the installation was not found and cancels the setup. After when computer logs on it keeps on with restarts indefinitely. Also when inserted my usb flash drive into the usb slot i had a folder inside called "User Data" and double clicking got me into the laptops documents. I searched around the net to find something but have so far come up with nothing. What kind of virus is this and how can it be healed?
