trojan horse downloader.agent.bf, HELP!

Hello, i am new to these forums and i would really appreciate it if i got some help with this trojan horse. This trojan horse is called downloader.agent.bf. i have no idea how to get rid of it, i run AVG and ad-aware and my AVG still tells me that this virus is infecting my computer. Everytime i open a browser or go to a new page on a website, another thing gets infected. I will attach a screenshot to this message. Also i have a hijack log. I hope this helps too.

Another thing.. My home page is re-directed to other links, and there is a major amount of pop-ups, as you can see in the screenshot! Thanks!
