I could not figure out what this Supernova thing was that keeps popping up on my computer. I went to the search engine and typed in W32 Supernova to discover its some kind of worm that I can't get rid of! Secondly I have the same WJView Error message as another thread discussed. It says: Unable to locate system/class: java/lang/object. I have had this error message for some time. How do I get rid of this too? I am on Windows XP. My last question would be which is a good and inexpensive antivirus software that I can purchase? Maybe that will eliminate some of this in the future. Kindly help Thanks.
