Ahh, how to get rid of this virus/spyware?
 

I downloaded a game from this Chinese site; I scanned for viruses and everything (all the directories, files, etc.) seemed ok, but when clicked Setup...
- My Anti-Virus (AVG Free) found some viruses
- My IE had these weird Chinese toolbars
- My IE homepage was changed to http://www.kzdh.com
- My computer was noticeably slower

I uninstalled the things it added through Control Panel Add/Remove Programs, but one still remains (I disabled it) and I don't know how to remove it. Even when I reset my homepage, it keeps reverting back to kzdh.com.

Scanning with Spybot and AVG again picks up nothing anymore.

What should I do? >_< Thanks for any help.

Since it looks like you just have some spyware issues, running AVG isn't going to help matters. The best thing to do is use some other anti-spyware programs, like Spyware Doctor or Ewido or Trend-Micro Anti-Spyware or Ad-aware. Victory by volume is the simplest route for stubborn malware.

I also recommend Ad-aware, it has served me well in the past. I also recommend changing your browser to Firefox. I did this a while back, and haven't had half the trouble that I used to with Explorer, but I did also ditch Norton around the same time, so this may have been a factor too.
