For that you boot the pc and always after a while the process C: \ windows \ system32 \ msiexec.exe running with windows only (without installing anything) and if I close rerun alone, I know this passed since installing the new avast 2015.10.2.2215 even if I leave you alone eventually closed. and then I know again no longer appear (I’ve been looking and running things and did not return to appear but I’m not entirely sure) but reappears if I restart the pc is passed as 10 minutes running, and then closes and (AFAIK ) does not appear more.
Is this normal?
I have seen that there are other copies of msiexec in:
C: \ Windows \ winsxs \ x86_microsoft-windows-installer-executable_31bf3856ad364e35_6.1.7601.1
and
C:\Windows\winsxs\amd64_microsoft-windows-installer-executable_31bf3856ad364e35_6.1.7601.17514_none_a7a77a3b9cb96ce6
I think they are legitimate routes too.
I enclose a HiJackThis but as I say look at the process and always at 0 cpu and just consume 2580 KB of RAM but not because it runs only.
Deputy HiJackThis reports and Malwarebytes Anti-Malware where nothing appears and the 2nd does not detect anything either.
Possible to avast bug?
