Ok guys.  I have not played on CG in a VERY long time and I need some help from those who know lots about computers!!
The last security scan I last ran was in September 9, 2013...  Before that, I had a Trojan Horse Virus.  It does not allow me to download any file.  When I ran that scan, I saw that my Antivirus Software detected over 700 Viruses including 12 Backdoors, allowing more viruses to enter my computer.  Since then, I have not been able to clean or restore my computer.  I need your help for me to Factory Restore my computer or completely wipe my harddrive.  I have no idea how to. I did some research already and found some tutorials for how to Factory Restore a Windows Vista (My computer).  I tried, and STILL did not work.  So obviously, I need help to reset my computer completely instead of having to buy a brand new computer ranging from $300 to $600.  If you are great at solving these problems, or had the Trojan Horse Virus yourself and managed to fix it, PLEASE HELP ME.  CG was my favorite server on Gary's Mod so I donated.  Please help.  Comment below or PM me on the website.  (My dad accidentaly deleted Gary's Mod AND Steam so I cannot re-download Gary's mod OR Steam because of the Virus.)
