I hope this is the place to put this but I have Personal Guard 2009 on my computer,don't know how it got there but it is.I cant open anything like Hijackthis or Malwarebytes' or just about anything.I have Avira Antivirus I did get that to run but it did nothing,I was able to run Malwarebytes and CCleaner last night but that thing was still there

How in the world do I get rid of this.Any help would be greatly appreciated.
