The first thing that should be addressed: How good are you on a Computer???
Are you comfortable with going into your Windows folder???...
Or, are you one of those that like to let programs go into those areas and make the necessary changes for you...
First off that site you are going to is a BAD site!!! By the the words in the line "Anal.Oral" its obvious that this has installed some Sexually oriented software..via, popups, redirects ect...any site that installs programs, spyware, malware, or whatever is worth avoiding altogether!!!
I bet you're using Internet Explorer as well for your browser aren't you...I'm not a big fan of that either because it allows drive by downloads...Firefox or Mozilla Browser is a good alternative...(Mozilla's my favorite)...Since switching to Mozilla I haven't had any such problems...
Also, I'm not a big fan for the Yahoo toolbar, much less the (so called) antispyware scanner thats integrated into it...and if I'm not mistaken...that in and of itself is spyware... (correct me if I'm wrong)
If it were me...I'd go directly to where that file is stored...examine the contents...and if it had nothing to do with the over all Opperating System, Delete it...But that's just me..
(For the fact that I backup my Registry, and Harddrives with frequent imaging backups!!! That way, no matter what, I can put everything back to perfect in mins...)
If you don't know what you are doing in the "Windows" folder, I wouldn't recommend doing this though...you may just make your system unbootable!!!
