Tyrael, to further help you. I will recommend a couple programs to you.
When it comes to spyware and adware, the top program I recommend is. Spyware Doctor. This baby costs $30, BUT you can download the free scanner. Now, it won't remove the spyware and adware it finds, but who cares? If you're good enough with computers, just look at the log and remove each one manually. If not, then maybe just download it to see how many you REALLY have. LOL.
Here's a link:
http://www.pctools.com/spyware-doctor/I actually have the fully registered version of Spyware Begone, but I would recommend the doc over that. And they cost the same too, the doc is better though.
For Antivirus, I would recommend avast! This also costs money, IF you use the professional version. In fact, they offer the home version free. And trust me when I say, it's as good as any paid for one, actually I would recommend it over paid for ones. I uninstalled Norton for this! (Norton sucks balls anyway) =P
