Im a newbie when it comes to computer knowledge. i have used ad-aware, spybot, norton, panda antivirus...and it found viruses which i cleaned, but many are still remaining....for example when i click to open notepad it installs xxxtoolbar and a pop-up appears Purity Scan and the same when i try run regedit.

Also in program files (C:\Program Files\ISTbar) which includes istbar.dll, i cannot delete this as it wont let me as it says access is denied.

I have googled all these viruses with no real idea of how to deal with it...

When i tried the online panda antivirus scan it found over 300 viruses, which i dont think u can fix online. it just informed me of it. i tried my offline version of panda and it found nothing on a complete computer scan.

I also downloaded Scan Spyware (shareware) it found loads of viruses in my registry but it would not allow me to delete the viruses as i have to make a purchase.

Can anyone advise me what to do now?
