please help

I have a serious problem with my computer. There is an abundance of these little .t files. These are small files that appear on my desktop, in my music downloads, in windows folders, and many other places. They are files that have no known operating program. Sometimes, they even show up in my task manager on the processes tab, along with some unknown .exe files, like aaaabw.exe. What program/virus/whatever generates .t files? what can I use to get rid of them?

Another thing: in my WINDOWS folder on my C drive, there are several folders that have a strange heading: $NtUninstallKB$. there are many variations, for example:

$NtUninstallKB893756_0$

$NtServicePackUninstallNLSDownlevelMapping$

$NtUninstallKB911567-OE6SP1-20060316.165634$

Inside every one is a folder titled: Spunist, which is full of .t files.

Are these supposed to be there? They have been there for awhile, but i'm pretty sure I don't remember them always being there. Also, these are all titled in blue text, whereas everything else is in black text.

And if they are not supposed to be there, would it be okay to just delete them?

If you know anything about any of what I'm talking about, please tell me.

 

Ok, thanks very much for the help. I never followed up before, because I took the actions listed in the previously mentioned thread, and assumed I had taken care of it, because the problem seemed to disappear for awhile. However, this time, I have had enough, and will be sure to be extremely thorough, thanks for being patient. Ok, so it was a good thing that I hesitated to delete all those folders. Still, since they are only the updates, now that the updates are installed, could I delete them?
