I'm sooooo over this and need help from you wise professionals! A week ago, I was checking the virus signature date (in Symantec A/V Enterprise 10.1) on my Win 2003 server - and it was not showing a date what-so-ever. I figured that the network nazi's might scan my server and find that the virus signatures were out-dated or worse, not showing, and get on me for that, so... First, I attempted to do the obvious and re-run a live update, it ran it successfully, but still no date showing. Then had the not-so-brilliant idea of just removing both Live Update and Symantec A/V and reinstalling it... Well, ever since, I have NOT been able to install it at all - no versions! It gets to the point of the installation where it attempts to "start services", throws up the following error: "1920.Service Symantec AntiVirus (Symantec AV) failed to start..." Ok, here's some other facts: * I am logged in as the Administrator * I did a search for that error code on symantec and followed their instructions, still nothing * I tried removing all instances of Symantec from the Registry, and then retry the installation... did not work * Other versions of Symantec also do not install, they get to the end, and then do a roll-back of the installation and state that it failed. * I tried the Symantec/Norton uninstall tool (SymNRT.exe)- upon executing it I get the following error: "This file is not signed so it won't run"?
