Need to delete files.....

There's a bunch of files on this laptop running XP Home, and I mean a BUNCH! They all have the same extension and I want to delet them all. There's over 5000 of 'em, maybe 2 or 3 times that, so using the Recycle Bin, or dragging and dropping is pointless. I'd like to just type in a command at the command prompt, or in the recovery console, or boot a UBCD4Win or PECD, and delete them from there. I know the command will be something like del c:\*.*\*.zzz if zzz is the extension. The problem is, the .zzz files are everywhere, in lots of different folders from My Documents, to Program Files, and everywhere else, and they're in all the sub-folders to; like in Program Files, even the HP printer folder has over 200 of these .zzz files. Some malware got in and created hundreds and hundreds of these files and put them everywhere. They have a size of about 16k. I've removed the main malware that created all these files, now I have to get rid of the files. I'd rather not format....

 

If you have some time, just use the search feature in Windows Explorer and when it is done finding all the *.zzz files, select all (ctrl + a) and delete them.

 

Luckily the root C: only had about 150 of the zzz files and they were easy to delete after booting to a PECD... I found that if I try to delete the zzz files in Windows, they replicate to the desktop.... so I have to delete 'em from the recovery console or a PECD


UPDATE-I think I will just reformat. I ran a full scan with AntiVir, and I cancelled it after it hit 23,152 files!!! All of them are TR.Crypt.F.Gen
