Near 100% downtime: System process grabbing 98% of CPU
Posted on 2004-04-16
Well, this looks like a virus....
Rebooted the laptop after a windows update patch (other workstations got the same patch - no problem) and I'm getting 98% CPU time allocated to the System process.
Which means that any keystroke has a response time like molasses.
All security updates are (I think) up to date.
Norton Anti-virus is installed.
So I thought I was good.........
An Attempt to run the full system scan was aborted after 24 hours (3,000 files of many many thousand files scanned).
I can access the laptop via my local network.
I am getting lots of Netsky.P type email viruses - all caught by the Anti-virus, but all spoofing my email address. The laptop was, (Until went dead in the water), my email workstation. (Is this related?).
The laptop Task Manager shows System grabbing thr processor time but I wondered if one of the other processes was in fact the culprit (Process tree issue?).
Any help appreciated before I trash the laptop (Real pain given that lots of licences are registered on it....).
[In case you're wondering.. CTOS was a great operating system I used in the '80s]
