I picked up something from a torrent download, thought I'd got rid of it but it keeps coming back. Problem 1) on booting up I get an error message pop up that says "RUNDLL Error loading F:\windows.o\System 32\opcwdpht.dll The specified module could not be found" Problem 2) in my active icon tray there is an invisible icon(!?!) that on mouseover says "Deliveries : 1 New" double clicking it opens an Internet Explore browser error page that has a title of "Internet Explorer cannot display the webpage" Problem 3) The infection or? Without warning sometimes when I'm using the computer and sometimes when it's idle windows start opening up in Internet Explorer, for the most part they're empty one or two go to spam advertising websites, if I'm active in Firefox a new tab will open, again it's empty. When this happens I get an error message telling me the computer is unable to delete the file, all I can do is close the error message. These can repeat a dozen or more times over, all I can do is close them. Then it goes quiet for a period of time. I deleted zone alarm pro and installed avg 8.0 I've also been running a trial copy of a-squared anti-malware. Hopefully having gone through the 15 stage pre-posting process my problem has been fixed, I don't know.
