Best way to remove problem Malware

Hi There,

I am trying to remove a bundle of Malware without success.

There is a bundle of listed programs which I try to uninstall through the typical Control Panel effort, but they remain listed there:

Buenosearch Toolbar
MyPC Backup
PC Performer
Speed Test 127
UnknownFile

I was looking at this weblink which provides a 5 step process for Buenosearch alone:

Not sure how much certain guides can be trusted. One of the first things I read was to download Revo Uninstaller, and I've not heard of it so I'm not sure if it's trustworthy..........
