One of my friend's laptop was having some virus problems. He had XP service pack 2 as OS and some antivirus programs but they were without new updates so they all could recognise, there is a problem but none of them could solve it. So i advised him to install AVG and run a complete computer scan hoping that it would solve all his problems. It appearently did but created another major one. The virus on his machine was affecting all exe files, so AVG moved all his exe files to vault. After the scan, taskbar on the bottom has disappeared, then desktop icons also disappeared. Now only blank desktop background his what is available. I tried going into safe mode and trying to salvage something there also the same problem. I am really sorry that i cannot provide more information that this as i don't have any and don't hope to get more as my friend is not the computer savy. Please suggest something.
