First, identify the malware and learn as much about it as you can. We have seen people , trying to execute "repairs" without proper information or skills and create more resulting damage than any virus could ever do.
Second, look in our database for information on the malware you have and start learning how to defeat it.
If it is a known trojan or virus program, look in the antivirus databases at McAfee or Symantec.
Do you have something that's not in our database? Let us know about it.
And don't forget the "Golden Rule" : Always, always, ALWAYS have a backup!
