I have Windows 7 home premium 64bit. I recently noticed a strange file "AM_Delta_Patch_1.115.788.0.exe". It was in Windows/Software distribution/download/install. Hitman pro found it during a scan and uploaded it, but it seems ok with it. I scanned it at Virus Total and it came back clear there too.
AM delta patch seems to be something to do with MS Security Essentials, which I have but when I do a web search on the exact file "AM_Delta_Patch_1.115.7880.exe" it comes back as a total blank and that is what has me a little concerned. If the file is harmless then I don't think I have any problems as my computer is running fine. The file and the folder it was in disappeared briefly and came back and the file is now "AM_Delta_Patch_1.115.988.0.exe"
I have done scans with MS security essentials, MBAM, and TDSSkiller all were clear.
Thanks for any help with this file.
