Explorer Using 25% CPU?

[Stefan Patric]

Per Stefan Patric:

No.

Okay. Do your malware scans in 'Safe Mode with Networking.' The
utilities need to download the most up-to-date malware databases before
doing the scans. That's why you want networking.

Report what turns up, if the problem persists.

Per glee:

Mea Culpa. I missed the part about the utility.

But get this: after booting in Safe Mode, I re-booted in regular mode
and the problem had stopped. I definitely re-booted multiple times
before that and the problem persisted.....

Ran MalwareBytes anyhow, and it came up with something in my D:\Temp
called GiantSavings.exe and I killed it.... but this was *after* the PC
had rebooted without the problem, so I'm guessing that GiantSavings.exe
was not a player.

Maybe some kind of massive one-time file scan like the one initiated
when .NET 4 is installed?

Your high CPU usage could be related to .NET, that is, some type of
scheduled maintenance, backup, etc.

I'll keep an eye on it and try the utility if the problem
resurfaces.

Thanks for all the useful info. My apologies for missing the
utility.

Maybe what you were seeing, was an AV reaction to a potential infection ?
The reboot, broke the loop it was in.
