This is what is meant by supplying more info...your machine is badly infected and again it could be a number of things.
First DLoad install and update the following:
Don't run them yet.
Spybot Search and Destroy
AdAware
Stinger
AVG Anti- Spyware ( different than AVG Anti Virus.
After updating and installing these shut down your machine.
Dis-connect from the web physically router/modem.
Re-boot into safe mode by repeatedly tapping F8 as soon as the machine is powered on.
Run each scan and let it finish completely ( this may take awhile as it sounds as you haven't scanned in awhile)
Let each program fix what it finds.
After this run Disk Cleanup and defrag. These might also take some time.
Power down and hook your connection back up.
DLoad Hijack This and post the log in our virus and spyware section. It will take more than one post to get it all.
We can then look further for nasties.
Be patient...we'll get you there.
