I am having the same problems, i am also unable to update adaware or my zone alarm fire wall. I've run adaware, malware bytes (it can update), avast regular and in boot mode (it can update),avg free (but can't update), avira antivir (can only update manually) suspect same unknown attack as described by jackx99 lots of problems started when my son accidentally down loaded something call "secure 2009"? First thing we noticed was start menu was erased and then discovered multiple virus and trojan problems. When i found your service i thought it might help to by pass the update problem but it hasn't. Help please,thanks,chet
