CPU Usage at max after driver updates.

Plates · 24 Nov 2012

I have an Acer Aspire 5750G and last night I decided to run some driver updates. I downloaded updates for the wireless card, chipset, synaptics track pad, and the camera. They installed fine but after I restarted I noticed that the nvidia GPU monitor is saying that igfxupdate.exe is running and now the fans are on max. Right now Speedfan is telling me that the CPU Usage is at max and the temps for the CPU are above 80C.(https://i.imgur.com/91ZHd.png) See that image for what Speedfan is saying. But when I open task manager, everything stops. I've left Task Manager open for now and the fans have become very silent.(https://i.imgur.com/vWRod.png) See that image for what it looks like with task manager open. So far I only tried system restore to before I started updating, but that did not fix it. Does anyone know what to do here?

I just googled igfxupdate.exe and came up with what might be your problem. I shouldn't post links to other forums but this might help you.
This is not my post submission but somebody elses.

Hi, after several hours of attemps I think I finally found the offender:
much probably a Trojan Generic KDV 792778, it pretends to be the windows service "Search Indexer" and it creates the fake executable: "igfxupdate.exe" which tries to connect in internet and rises the cpu load all the time till you open the task manager to hide itself..
So I solved the problem like this:
in the windows services management console I disabled the above fake windows service (it was in automatic start mode) and after I deleted the igfxupdate.exe file that was in the windows system32 folder..
I rebooted the pc and I deleted the same service with the command: "sc delete SearchIndexer"..
problem solved! cpu back to normal level, not more unwanted connections and not more igfxupdate files around ..
anyway for more safety it's better to do also a complete scan with a good antivirus/malware software.

PS...Google is a valuable asset for looking up problems I just wish more would use it to its fullest potential.

Ahhh I found that post last night but the solution was not posted when I checked. Thank you very much because now it is fixed. Do you think the driver updates were the issue or was it from something else because the igfxupdate.exe says it was created on November 21, 2012 and not yesterday.
