Most of the modern viruses/spyware use this key. And some of them create files with random names.
Try Google by file name, or use antivirus/spyware scanners to identify the infection.

hi

if u are sure that there are dll files that are unhealthy there are two things u can do that can help
1. run hijack this and try and fix the entry and then go to the misc. tools and try and delete the dll files on next boot

u can also download something called the killbox that kills processes running on the computer. and deletes the process

go to google and type killbox download and the first site that comes up will be a bleeping computers site. 
on downloading killbox u will need to type in the path and file name and then kill the process and delete the file.
make sure that u are sure that u know these dll files are the naughty ones,
u can also try a spyware scan b4 that like adaware or microsoft antispyware beta
