Is "Isass.exe" a virus or what?

[momditty]

This morning when I went to work I left BearShare on. There shouldn't have been anyone else on the computer. When I got home Zone Alarm had an alert for LSA Shell Isass.exe saying it was trying to access the internet. I looked it up and on one page it says it's a virus/trojan horse. On another it says it's something to do with Windows verifying user logins? What is this and can/should I delete the files I found for it? Thanks.

Don't worry about it. ZoneAlarm gives many a false positive. :hole

If the full path to this program is not C:\WinNT\System32\LSASS.exe (Windows 2000) or C:\Windows\System32\LSASS.exe (Windows XP, 2003), then you have the W32.Nimos.Worm virus or some other virus.

SO it depends.
