I applied service pack 3 for my MS/SQL 2000 Client (Personal edition) a week
ago. I am using Win2k Pro. This past weekend, I logged on to internet as
usual, though did not use SQL Analyzer nor Enterprise Admin. Now I could not
brinhg up Enterprise Admin, the cursor stays for a while then turned back to
Pointer. However, I can logon to SQL Analyzer and see all my data. Is my PC
infected ? How can I find the worm ?

TIA
