Hi :
If "the thing" is covering up other files, then you MAY have
a "rootkit" !? The best place to explore this possibility &
get help would be the volunteer Rootkit Experts at :

For detecting & quarantining "worms" I recommend 2
possible program(s) NOT on Eddy's link, namely :
1) FREE ver of "SUPERantispyware" from :
www.superantispyware.com ;
2) Ewido ( also FREE ) from :
www.filehippo.com/download_ewido/?1208 .
