Worm Removal

Can you please advise how a novice can get rid of this worm. Delila

I took a glance at the main

I took a glance at the main file only but from what I remember you can try to follow this steps:

you are infected if the size of msgs.exe is not equal to the size of msnmsgr.exe, msnmsgr.exe is really small; in this case you can look for the files suggested by Drean: sprT.exe, alpha.exe, Xinstall.exe, drsmartload.exe. I'm almost sure the name of the first file is not always the same; I think the 4° letter is random. If they are running kill these processes.
Kill msnmsgr.exe (which is the worm...), delete it and make a copy of msgs.exe renaming to msnmsgr.exe.

You should have solved the problem; someone who did a deeper analysis can confirm it?


That sound correct, also, remember to reset the Internet Explorer settings, because the worm changes them so every website can execute code on your system.

Also, since the worm install a shitload of spyware, so you should run a few tools that can detect and remove spyware and virus, tools like ewido, drweb cureit and superantispyware.
