teens and endless viruses

hello. i was just wondering if someone could tell me if the following files are ligit or not. i'm having a hard time trying to get a decent search on the entire file, which leads me to believe they are spyware.
ocsetup_cbs_instal_netfx3.dpx
.perf
.etl

vista 32 bit os. i don't think its part of netframework 3 but i don't wanna delete it just in case and i'm so hoping to prevent another reload :cry

thanx

 

i'm replying to myself. i have so many computers in my house with so many different os that it gets confusing. i looked for those files in my laptop which is os 7rc 64 bit and they were not there. but.... in my main pc, 7rc 32 bit there they were. which leads me to believe that the 32 and 64 have different file names. sorry for your time. i was comparing apples and oranges.

so off i go to track down the rest of those lovely endless viruses:-o
