First I will tell you I run XP Home Edition on my pc.

I use the built in firewall in XP Home and I have the Microsoft Antispyware
and all available updates (critical). I have SP1 and I really do not want
SP2. I use the Prevx Home Anti-Virus software and I do regular scans on my
pc. I am an internet surfer and so I had to learn to "clean up". I use CW
Shredder, Hijack This and I have my computer configured so that nothing
starts up in msconfig. I use Stinger and Panda on line scan and Adaware and
Spybot S&D.

Even with all of that I recently was attacked by a couple of virus's
W32/Sdbot.ftp.worm and W32/Sdbot.DOF.worm. The first one was in the file
C:\Windows\System32\phhh.dll and Stinger found it. The 2nd one was in the
System32\TFTP1756 and Panda found it . My question is there is still a file
there called TFTP1544. I have learned that TFTP stands for Trivial File
Transfer Protocol and is used with the TCP/IP Protocol. There is still a
couple of files in my system 32 folder that I am curious about. One is a
TFTP1544 and the other is a TFTP.exe, are they supposed to be there?
