I've been getting this on two machines since they upgraded to version 2015.10.2.2214. It reports:
Process 1764 [explorer.exe], memory block 0x000000006EE30000, block size 659456 (ashShell.dll) Medium Threat: Win32:Evo-Gen [Susp].
It reports no problem with any files on disk, including the two mentioned in the message above.
I have run Kaspersky TDSSKiller and Norton Power Eraser, also without finding anything of consequence.
Both machines run fully patched Windows 7 Professional SP1.
Looks like a false positive to me, but I would like some advice before I ignore it.
Thanks
