Just updated my ZASS and ran a spyware scan, and once again, the following .dll was picked up as being a trojan. This time the trojan was identified as Win32.Trojan.Proxy.Repsamo.1 (nothing on Google about this), and the file identified was from my graphic card software, ATI, and it is in the Program Files/ATI Technologies/ATI.ACE/atiacmxx.dll. This .dll is an ACE Context Menu item, 68 kb in size, created April 19/05, file version 22.214.171.124.
Because of other false positives, I have my software set to report only, which the gurus here advise NOT to do [and please understand, I do not consider myself an expert!], but I have found from past experience that restoring an item from quarantine doesn't necessarily mean you get it back, because ZASS does something to the entry in the registry regarding the quarantined item. I permanently lost a .dll that way, but it was one I didn't need, so I was lucky that way.
I had this file scanned at Virustotal.com, and it came up as clean. I'll be sending a report to ZA.
