ZA is easy to shutdown or prevent loading at startup. My PC has no
"vsdat.dll" file on the "c:\" drive, running Pro version. There is a
"vsdata.dll". This may be the source of your problem. Suggest you
uninstall using the ZA uninstall on its menu. Then, reinstall. You need a
firewall.

I'm running 98SE and Zone Alarm.

After installing new 98SE patches and a new Zone Alarm, I keep getting
message boxes saying the program has performed an illegal operation and
will be shut down. It says there is a page fault in vsdat.dll when
called by vsmon.exe and zlclient.exe, which are components of Zone Alarm.

The CPU is used 100%, and the system doesn't respond to ctrl-alt-del.

I try to delete the exe and dll files but can't because they are in use.

I don't know how to kill the task or somehow prevent it from starting at
boot time.

Please advise.
