Inactive Virus, Malware, Trojans

[Inactive] Virus, Malware, Trojans

Hi, I am here to get some help and advice about removing annoying and hidden problems with my computer.
I am running an ASUS with Vista and having difficulty.
Since this weekend we got infected with trojans which somehow got past Spyware Doctor. We've tried alot to remove them, and most have been killed, but there is still one (or two) which is annoying but has not been detected by any antivirus programs we have tried. So I cant really tell you what it is, but what it does:
1. Doing a search on google on anything (happens more with computer related things), it redirects me to a irrelevent site, I have to go back and reclick the link multiple times over to get to where I want.
2. A recent problem my mum noticed, we cannot get Windows updates
Error Code: 80072EFF
And trying to access the windows update site doesn't work with just and INSTANT error message saying "The connection was reset ", even when I tried posting the link here, it was the same message.

My IPT teacher told me to download a few programs to help, including:

• Super Antivirus (to run with full scan)
• Malwarebytes (To run with a full scan again)
• Ccleaner
• and to buy ESET instead of Spyware Doctor but my mum doesn't have the money

Please help

 

back again with more info, sometimes periodically a new tab will open whenever i am using a browser, first it went to this christian religious site, but before anything downloads it get reREdirected to http://rc12.overture.com, this is strange finding that that searching the link and finding this (http://forums.techguy.org/web-email/711573-what-rc12-overture-com.html) that it's something to do with yahoo, even stranger is that it's blocked by Spyware Doctor
Curiouser and Curiouser...
