Having used Combofix previously for over a year, I tried downloading the current version from a couple of the usual sites. This was on Sept 11, 2017 and both times on both sites, I was redirected to download and install a program called Plumbware. The popup message also said that Combofix did not work on Windows 10xx and that they recommended (supposedly representing Combofix) running that program. The program had a direct download link, which did not seem right.
Suspicious of this, I did not proceed with their suggestion.
I did however run Malwarebytes ADWcleaner and it took 3 passes to finally get a clear report from the program. The first two runs reported over 32 incidences of probable contamination.
Today I went to the same sites and was able to dl a file that says it is ComboFix.exe, no popup this time (today is Sept 12, 2017) and so I downloaded the file. The file details are: ComboFix NSIS Installer, file version: 188.8.131.52, Copyright: sUBs, size: 5.39MB.
However when attempting to run what seems to be a legit copy of ComboFix, Windows User Account Control reports that the Publisher of this file is Unknown. (the system is running Win 7 Ultimate)
How do I tell if this is a legit copy of ComboFix ?
I have had excellent results using ComboFix before, but now I am concerned that there is some sort of potential interference going on.
Any and all advice will be appreciated.
