Hi. I'm looking for some help removing spyware, and this seems to be the best method available.
I'm not very computer-proficient, so I don't know if this information helps at all, but I felt I should include it anyway. I've put the HJT log last.

- The virus/malware infected my computer on either 12/30/08 or 12/31/08 and it began as isolated non-frequent forms of annoyance (shortcuts to inappropriate stuff on my desktop, pop-ups, ect.) to continuous, seemingly unpreventable things (a flashing "WARNING" sign, clearly from the spyware or scam thing that recieved my info from the spayware, has covered my desktop; my documents folder opens up occasionally as well as pop-ups for a scam scan and antivirus pro 2008 which are always the same pop-ups, fake security alerts from my taskbar, ect.). Also, things like "related computer connection" or something similar to that (it is that connection that lets you work on a computer from a different computer) appeared in my files and programs. I removed them, but I fear that some kind of connection may have already been made.

- I downloaded and attempted to install Spybot S&D, Malwarebyte's Anti-malware, and Ad-aware 2008 (at seperate times), but whenever I tried to install them the same thing happened for each: the run/cancel window opened, I clicked "run", and for a moment a "choose language for installation" window opened, but immediately a cluster of application errors appear and prevent me from continuing installation.

- I was able to download and install Norton Antivirus and run scans. It detected trojan.vundo among other trojans and spyware-type things (there was a cookie tracker, for example). When Norton claimed to have fixed the viruses, I restarted my computer but nothing had changed. I did this multiple times, but to no avail.

I really appreciate any help that you would be able to offer . And finally, here's the HJT log:
