Hello,
One of our employees gave back his laptop that was not booting.
The winlogon.exe process uses between 90 and 100% of the cpu. It boots but very slowly.
The problem doesn't happen in safe mode.
I don't know if this can be a malware or something else.
Thanks for your pieces of advice

Thanks for the info Cranky,

may I run all these tests in safe mode ? I'm not sure I will even be able to read the usb key while the processor is 100% used by winlogon.exe.
Will a malware be detected in safe mode? (the processor is free in safe mode)
TIA

Yes, I would say that most of these can be ran in safe mode.
The online scanners will have to be ran in safe mode with networking.

Cranky,

After having launched all malware detection tools, the issue was still there.

I found a thread of someone who had the same problem and solved it. It also worked for me. Here is the solution.

Delete the contents of C:\windows\csc which resets the offline files & folders sotore. There is also an alternative method of cleaning up the offline files:

I printed the Malware Removal procedure which is very useful and complete. I'll use it again.
Thanks for your help. :tazz:
