I was somehow infected by some malware. It seemed to occurr when when I was issuing some commands on my laptop to perform a task to flush some authentication credentials for logging onto one of our servers. I wasn't sure which command was the right one to issue, and I issued a command "ipconfig /flushdns". I don't know if this could have caused it, but the infection seemed to happen right after that. I had McAffee Firewall up and runnning on my laptop, and we're behind a Sonicwall firewall. There is a possibility I did have a VPN connection opened to a customers network at the time (perhaps that could have been the source).
In any case, here are my symptoms:
1) When I open a broswer, my browser displays the "Insecure Internet Activity. Threat of virus attack" page. Subsequent browsing usually (it's inconsistent) results in the browser crashsing/gpf'ing.
2) In addition, a dialog intermitently pops-up saying "Security Alert Center", "To help protect your computer, Windows Firewall has ...". It's obviously a rogue dialog.
3) My Microsoft Outlook 2003 client is also crashing now intermitently. Plus the computer is running slower than before.
What I've done so far:
I've run Kaspersky Anit-virus (Trial version), SuperAnti Syware (Free edition), a-squared free, Malbytes Anti-Malware, Spybot and also SmiitfraudFix.exe (twice), all to no avail.
Win XP Professional SP 2, IE 6, Dell Laptop Lattitude D820.
I'm ready to post a HiJackThis log when requested.
Thanks in advance for all the assistance.
