10. Dr Watson PostMortem error :

Can you check to see if Dr Watson is configured as the default debugger?

In the registry, check:
HKEY_LOCAL_MACHINE\Software\Micros­ oft\WindowsNT\CurrentVersion \AeDebug

The key will be called: Debugger and the value will be something like: Drwtsn32 -p %ld -e %ld

If so, perhaps remove that key, and see if that solves the problem (if Dr Watson crashing is causing the lockup). If you are still gettin the lockup, then the problem is somewhere else (e.g. the original NJStar problem). Try uninstalling that application.

If you need to reinstall Dr Watson as your default debugger, run:
Drwtsn32 -i
at a command prompt

9. Explorer.Exe Virus :

We've found multiple infections in a few machines over the years. It's known as the dlder.exe Trojan and it drops another "explorer.exe" file in a separate folder,
normally in 'C:\Windows\explorer\Explorer.exe'.

Please note that you have a legitimate original
"explorer.exe" in 'C:\Windows\explorer.exe'

It also drops a startup file in your registry so it will run silently at startup...normally
in your Local Machine Registry: [HKLM\SOFTWARE\games\Clicktilluwin]. However; we have also found
the Clicktilluwin entry in ‘HKCU’ over the past few months. That said, you should do a search find on your total
registry for the phrase 'Clicktilluwin'. Go to the link above and follow cexx.org's manual removal, then search your
regedit for the 'Clicktilluwin' reg-key and you should be fine.

Anytime that you have explorer.exe running over....say....25,000K to 30,000K in the
task manager, it's usually indicative of infection.
