This virus creates sub files called “Syspilog.pil”, “KarnaDrv.dill”, and “Wowinitcode.dill” which you have to delete separately. When installed from wherever it prevents you from opening Windows Explorer so you can’t look for it or what’s going on. I happened to have a copy of an old, really good, program called XTGold that operates in Dos and you can look at everything and delete the junk. I think I have the computer clean now as I am running a scan with CA Security Suite. Norton Antivirus found it but could not delete or repair the file so I dumped Norton. Prevics, not sure about the spelling found the files but I’m an old man, been retired since 1996 and can’t afford to purchase a program every time the computer goes crazy. Need “FREEWARE” no tricks to get it eithere as the “Prevics” let me download and find the bugs but then I have to pay $15.95 just to use it for a month. Will have to find other things that don’t cost so much.
