On my self built computer I run Windows XP Home edition with SP2 installed. Firewall Zonealarm free edition and antivirus AVAST free edition.
Before installing Spywareblaster, I ran a tool from Panda: www.pandasoftware.com/products/activescan.htm. After having done that Panda put some files on my computer for continual supervision. After re-starting the computer my AVAST free antivirus software told me that a file PSKAVS.DLL was infected by Win32:CTX. I moved the file for safety to the AVAST virus chest.
If I am not mistaken this file is from an antivirus product (PANDA or AVAST). It seems strange that an antivirus firm should be the origin of a virus. What is happening here and must I do something to protect my computer ?
