I formated my HD a few hours ago due to general poor performance and a few random error messages. Everything has been running fine except i keep getting these strange pop up messages. It happens at any time / any where, wheter im browsing the net or in my documents. It doesnt look like a windows pop up window so im not going to trust it. It says
"Message from SECURITY to ALERT user on 'date + time'
STOP! SCAN CRITICAL SYSTEM ERRORS"
Obviously its crap and points me towards a random list of websites such as click here and click here
I used to use Zonealarm and AVG but changed over to BitDefender as recommended by PCadvisor and have never experienced anything like this.
P.S ive ran spyware programs but they find nothing
The reason I asked about SP2 is that I think it turns off Messenger Service. Maybe you turned it off previously. Anyway, you should install SP2 as it fixes a lot of vulnerabilities in Windows - more serious than the odd pop-up.
