Title: "extension.mismatch.software distribution.edbtmp" I scanned my PC a couple weeks ago and during my normal routine scan malwarebytes detected a threat. Anyway i let it finish scanning and once it was finished i scanned with Bitdefender Total Security 2013 and the same file came up clean. I uploaded to a online virus checker and all the virus engines showed as clean. Can someone please confirm if the file above is a security threat?
