Hi all,

Running Vista Home Premium SP2 w/Norton 360 Premier Edition
I ran Panda Activescan 2.0 this am which returned a few cookies
I then updated and ran Malwarebytes which returned:
Files infected:
C:\windows\system32\ctfmon_tk.exe (Trojan.FakeAlert)

However, Microsoft seems to state that ctfmon_tk.exe is a necessary component of Office

However, Malwarebytes states to delete it

Am I ok to delete it?
I am running Norton 360, SuperAntiSpyware, AdAware, Spybot-SD Resident

If this is a real trojan, how did I get it if I have all of this protection?

There's a subtle difference in the file referred to by Microsoft and the file you mention

When you run a Microsoft Office XP program, the file Ctfmon.exe (Ctfmon) runs in the background, even after you quit all Office programs.


C:\windows\system32\ctfmon_tk.exe (Trojan.FakeAlert)

Malware often uses filenames similar to those of legitimate system files to hide more effectively. The file that MBAM has detected is indeed a trojan; you should allow its removal.

If this is a real trojan, how did I get it if I have all of this protection?

That's a difficult question to answer precisely. There are countless possible ways that such a trojan could end up on your machine. Perhaps the best answer I can give is that no amount of security software will guarantee your immunity from malware infections. Malware writers are constantly devising new ways to slip past security software. The best defense against malware is to make sure all software stays up to date, and practice safe surfing habits. :thumbsup:
