No, I'm absolutly sure that it is not malware! I use Ad-ware SE and SpyBot(they are updated!) I have very good antivirus software: antivir PE! antivir PE! Good firewall: Kerio!
I use Reg supreme. Everytime I scan it finds something like: the file ... is not existing. Then I say: repair it. The answer: "Evrything is repaired or deleted ... The repairing was succesfull." Then I make again a scan and then the same problem is comming: "The file ... is not existing(the file is realy not existing!)
I make deep scan.
Any suggestion. Personaly I thing that is software problem and it is comming from Reg Supreme.
P.S. Sorry for the late answer!
