Did a check on Google and tried a on line scan with Panda Active scan, this found 3 threats but as I do not have a credit card was unable TO PAY TO HAVE THEM delete the entries, or find out what these threats were.
Have ran the following programs, which found nothing but tracking cookies, AVG Anti-Virus, AVG Anti-Spy ware, SUPERAnti-Spyware, Spybot-S&D. Tried a system restore that has not helped either. Can anyone suggest any other course of action to solve this problem?
