i'm sorry if I am in the wrong room, but i've been having
strange activity on my computer. I am running Norton
Internet Security 2004 and I am recieving massive numbers
of program control popups from NIS saying a remote system
is attempting to access my computer with various IPs. I
have blocked them all, but this is getting very annoying.
My doom, Netbus, and several other trojan horses are some
of the culprits. Norton also popped up lsass.exe is
accessing my computer too. What is lsass.exe? And, should
i be worried about it?

I have scanned my comp. It was clean. I am sure that it is lsass.exe and it said that it was from Microsoft, but when I ran an IP analysis, it came back as unknown. Normally anything from Microsoft would have registered. Is it possible for someone to fake
the name lsass.exe?
