Look up in your registry for jdbgm, its an exe file that is a serious
virus !
It gets into your registry everytime you are entering the internet and
receiving junk mail, even if you don't open the attached files !
Go to "run" and type "regedit". Then go to "edit" and using "find" type
"jdbgm" then you will probably find there some of those "exe" files,
delete them .Run regedit several times to be sure you delete them all.
If you receive daily junk mail look up very often.
