Ive just installed windows 7 fresh install. I first installed avg then started installing windows updates. I then started to encounter windows update errors which have since been resolved sort of. Was running update today and got a trojan horse inject.atfo warning. I really dont understand that at all the object name is

Trojan horse Inject2.ATFO, c:\Windows\winsxs\wow64_microsoft-windows-scripting-evbscript_31bf3856ad364e35_6.1.7601.22535_none_b149979f92145d02\vbscript.dll;"Secured";"8/29/2014, 1:26:31 AM";"File or Directory";"c:\Windows\servicing\TrustedInstaller.exe"
How would someone send a payload over windows update anyway? Did a hijack this scan without anything concerning as well as a malwarebytes and avg full scan that came up with nothing. pretty confused as to why avg thought a windows update was a trojan. To avgs credit it seemed i was installing the same updates over again and they failed to install because of that so maybe avg thought the windows security update was doing something harmful to the existing one ?

the thing is it doesnt show up when i scan it only pops up on the resident shield when i was installing updates or when i try and open the file or even right click it in explorer

Bob, In order to analyze it please provide AVG with GMER (http://kb.avg.com/articles/en_US/How_to/GMER-Scan-Result/) and AVG scan result export (http://kb.avg.com/articles/en_US/How_to/AVG-scan-result-export/).

bob riley quote 'virus total is showing both files as clean'…
Bob, Which files are you referring too? Provide the info previously requested & AVG will confirm if your system is clean or not?.

Bob, It may well have been a false detection that was cleared by a vdb update.
