Why does machine shut down during scan?

Jump to solution


Running Windows 7 Pro/64 with latest updates. McAfee Security Center 13.6 with auto updates. Subscription does not expire for 264 days.

I have "auto scan" to run on Wednesday at 2 PM. As it scanned it got to 15% and shut my machine off.

I rebooted and did a manual scan, this time it got to 22% and shut down.

I have manually rebooted 3 times on different days and get the same result.

When I reboot and open McAfee Security center it urges me to do a scan but doesn't tell me the date of the last successful scan.

Any ideas as to what's going on?

To all who offered help I thank you. However a "half" a cigar goes to Ex Brit, when he proffered the "overheating scenario"

and the other half of the cigar goes to a netizen of an AMD forum who suggested TIM could fix my computer.

So I got TIM and  was able to do a complete scan to 100%.

If you're like me you wondered who TIM was? TIM= Thermal Interface Material, which I always just call CPU goo or grease.

The TIM on my machine was totally dry and not enhancing the heat sink affect for the CPU. The new TIM cooled it down a lot.

I moved this to the VirusScan section for better support.

Shutdown during a scan is worrying as the only reason I can think of is that the machine is overheating.  Is there anything else running?

If this is a desktop, are all your fans working and clean?   If a laptop then I'm not sure and Technical Support would probably be your best bet in any case.

I forgot to ask, McAfee relies on Internet Explorer for function, so do you have IE11 installed (I'm assuming 7 is actually 7 SP1).?  (It doesn't have to be your default browser).

Running IE 10, you say I "must" have 11?

Or, McAfee "may" run better with IE 11.

thanks

Yes it may run better as it relies on the latest available for whatever system it's installed on.

Also I suggest you do a chkdsk as per this Tutorial as the scan may be tripping up because it can't read some sectors: Disk Check - Windows 7 Help Forums

I would use Option 2 - the Command Prompt method and use the /r delimiter so it checks everything and makes corrections where possible.

Installed IE 11. Ran a "Quick Scan" it was O.K. However now McAfee doesn't offer me a
deep scan". Will wait till tomorrow and see if I can do a complete scan.

The "ckdrv" produced nothing.

Thanks for your help. Will check tomorrow and see what happens.

Chkdsk you mean, well it was merely a possible reason.   If there are further issues I think your best bet is Technical Support.

Good luck ;-)

Machine is a desk-top. Nothing else running at shut down time. Notice that McAfee uses 54-60% of my CPU.

Used "Virtual Technician" it found two errors in registry and repaired them....did not fix my problem.

Cabinet fans "appear" to be working BUT can't remember last time I have heard them kick into high gear (3 speed).

Exhaust air warmer at 20-24 % scan than at start-up.

Will have to dig in to cabinet to see about CPU fan and  video board fans....ugh....had thought about that really didn't want to.
