The fact is, imho: you shouldn't disable WebShield. It's a drastic reduce of the protection level. Let's focus on the problem and not trying to get rid of the bitterness of the solution.
I fully agree as I said in this thread, too.
But IF he still turns Webshield off, ashWebSv.exe continues to run, he says.
By me the Service stops if I try to disable the Webshield.
Why would you want to disable ashWebSv.exe, mine is at Manual and that should be ok, or...
