[ale] XP Malware - XP Security Center

[Daniel Howard]

Short question: do you have a win XP malware removal tool you recommend?

Long version:

I've googled myself to death on this one.  I've tried everything so far 
except purchasing a new Windows antimalware program (currently use 
ClamAV and Spybot SD).  I've somehow picked up a malware program that 
puts a red circle with a white X in it in the task tray that keeps 
trying to get me to buy some rogue antispyware program called XP 
Security Center.  I researched it, sure enough it's malware (rogue 
antispyware), found the names of the files used (winivstr.exe and 
braviax.exe) and couldn't delete them due to being in use, so I booted 
my XP install disk in recovery mode, and deleted the files from all 
locations found from searching (in the WINDOWS and SYSTEM32 
directories), and dang if they still don't get replaced on reboot.

So, I probably need to purchase a better tool for removal, but there's 
so much crap out there that poses as malware removal that is likely yet 
another malware package.  Is there a good malware removal package that 
would work on beasties like this one?

Thanks, Daniel
