explorer.exe

[Frank]

On startup, I open Windows Task Manager/Processes Tab, to
list all the Images and CPU usage, because it seems to
take quite a while. I've noticed during startup that
explorer.exe uses up to 20% during this time, even though
I've not opened Windows Explorer.
..
Then periodically, when I've been on the computer for
several hours, my system will slow down, the hard-drive
is being accessed constantly for several minutes at a
time. I check the Task Manager Processes, and
explorer.exe is using up 90% of CPU time.
..
What is going on and how can I fix that?

What does a scan with a current antivirus program (meaning a version not
later than 2002 and using updated virus definitions) show? Also, remove
spyware with Spybot Search & Destroy from www.security.kolla.de and
Ad-aware from www.lavasoftusa.com. Be sure to update these programs
before running them. It is best to run antivirus and spyware removal
tools in Safe Mode.
