Let me preface this by stating that I recently cleaned up an infestation of "#37049" CWS spyware. The computer appears to have been clean for 12 hours.

Today, a pop-up periodically opens with the message "Buffer Overflow, systems affected are Windows (in various versions)" and directing me to www.updatenow.org for a fix.

I ran Ad-Aware, Spybot and Spyware Doctor. Alexa was found and cleaned up. After a few hours, Alexa re-appeared on the machine.

Is www.updatenow.org a legitimate website? I didn't try to access it given my recent battle with #37049 or is this a legacy from Alexa or #37049?

My HJT log file looks clean:

Hi starman
First it is very important that you get and apply your security patches and updates-

Internet Explorer
Windows updates

As for www.updatenow.org I don't believe it is legit.Now close all browsers and rerun HJT. Check and click fix checked for the following-
O4 - HKLM\..\Run: [mseq.exe] C:\WINDOWS\system32\mseq.exe
I don't know what this is. Do you?
O4 - Startup: Phone Tool.lnk = C:\Program Files\Classic PhoneTools\Phontool.exe
Remove these if you did not place them-
O6 - HKCU\Software\Policies\Microsoft\Internet Explorer\Restrictions present
O6 - HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel present

Then find this one and post it's properties-
C:\WINDOWS\system32\mseq.exe - rename it C:\WINDOWS\system32\mseq.old
until we know what it is. You may need to show all hidden and system files and be in safe mode to rename it.
