A dancing girl has installed herself on my desktop and I am not laughing. Tried to download some music but got her instead! I scanned the file before opening it and no threats were detected but obviously it wasn't the music. She tried to change my homepage too, but I blocked that. I went in programs and uninstalled the new program, but she's still here! My malware and anti-virus aren't coming up with any infections. So what's she doing here and how do I get rid of her? She's not even my type. I'm not into blondes.
Geek squad, please help!

press (windows key)+R to get the run dialog and type msconfig (click ok)

go to the startup tab and disable anything funny looking (this is non permanent in case you screw up)
can kill it with task manager if you know the app name (right click task bar, task manager, or control+alt+delete and click open task manager if prompted) by right clicking the app and selecting end process

Let me know if you are still having problems.

Flan's process will work to kill the running program, but may leave the software installed.  I'll need a little bit more information to do a proper search.  Is there a program name you can identify?  Do you know where you downloaded it from, when it tries to reset your homepage, where is it trying to send you to?  That sort of thing.

I did a quick search for virus/malware that had dancing girls on the desktop and I didn't come up with anything really solid.  It might be a version of that pseudo virus kill software that gets into your machine and says you are infected with dozens of viri when in fact you aren't but it is trying to get you to buy the software so you can turn it off. 

Let me know.

Have you run Malwarebytes?

If not I'd give that a go. Depending on whatever flavor of nasty you got, you may have to download it on another machine and transfer it over via some storage media.

Thanks all. She left after I rebooted, as did her icon in the tray. I'm still a little nervous though.
