So I posted my original problem in the normal Avast! Free/Premier thread and I didn’t really get anywhere with it… and was recommended by bob to come here…
Basically… I’ve seen some very suspicious behaviour coming from Avast the last week or so… whenever I try to do a manual scan for new virus definitions on my system or the system automatically detects new definitions to install… it will act completely differently to how it used to install them previously to this behaviour…
It runs 2 instances of the instup.exe process… but the first process appears to exit very quickly… after the first process shuts down, the second will activate and according to logs I have read in the Persistent Data/Update.log it activates a file called ngiodriver_64.vpx and auto-creates 2 temporary services with randomly generated service names every time… I don’t know if this is a sign of malware or a virus trying to stop the first installer from installing an update and then the Antivirus Self-Defence Module intervenes or not…
This is a vague log of what the second process does:

About a week or more ago, Avast! would just activate a single installer which would update the definitions quickly without any sign of large amounts of resources being used… but the way it updates now… takes around double the amount of RAM it used before to update itself… probably due to there being 2 processes of it running now.
I was also told in the other thread that this could be the work of NG, as ngiodriver_64.vpx is supposedly associated with it… but according to my logs above… the NGAssistedVirtualization status is false.
I don’t wanna get paranoid here and say that this is a virus or malware immediately but I’ve never seen Avast! Updater act like this before and my system has slowed down on startup lately (more notably the svchost processes are delaying a lot longer than they should be.)
