How do I remove this unknown malware?

[LukeNukesEm]

So ever since dec 12, my computer would have slowdowns and the malware would attempt to redirect me to sites. Kaspersky blocks the redirect, and its a different website almost every time. I remember installing ummy youtube video downloader (suspicious I know), but when looking at the site and after successfully installing a youtube video, it seemed legit. After getting computer slowdowns I deleted ummy. I am still getting slowdowns and the malware is always trying to redirect me to another site. I've scanned with kaspersky, hmp, and malwarebytes all up to date and no threats found. Note I took a snapshot with voodoo shield before installing ummy just to be safe, but I want that to be my last resort. If I can remove the malware without losing the video I installed, that would be great. Thanks for the help! In the meantime I set voodoo shield to paranoid to keep my compute on lockdown.
