Hi essexboy,
Also performed a scan with Sophos Anti Rootkit, results: No hidden items, Time taken: 7 min 59 seconds.
That means Gmer: no results; MacAfee Rootkit Detective: no results; Gmer's stealth scanner CatchMe: no results, and also IceSword results, but they are known as part of Comodo's software. So more and more I lean to an FP on behalf of the Prevx CSI recent version, as I had that for some time and it did not signal anything with the former scanner, the only funny file I have in system32/drivers is 剐䍏塅ㅐ〰匮卙 = procexp.sys - but I checked on that some time ago and no malware found,
I did another test, uninstalled Precx CSI scanner then downloaded it again: it found the same Device.exe
but oh surprise as other processes now Hidden Process 140 Hidden Process 732 and Hidden Process, all green, and detection after Comodo FW alerted that the scanner wanted access to the Internet, this was enough for me to decide to uninstall Prevx CSI free scanner (trial without possibility to delete, that is included with the paid licensed version) period,
