Help with 'Search Here'/'help.do' malware?

Hi, and thanks for taking time to read this post. Although I am yet to notice any adverse effects from this malware, I want to just get rid of it all and be able to use my computer safely again.
Alright, let me get right into the problem. I'll add now that my laptop is running Windows 7 Home Premium on a 64 bit OS, and I use Mozilla Firefox as my main browser.
The problems started when i stupidly downloaded an flv player from a dodgy-looking website. I should've known not to download from such a site, but went ahead anyway. However, after some quick reconsideration I stopped the installation process midway (after installing the setup files, which were apparently enough to infect my computer) and thought that the problem would end there.
I proceeded to re-open Firefox, and found that a 'Search Here' tab had appeared in the toolbar. Not really thinking much of it, I put Mozilla Firefox into Safe Mode which made the tab disappear, then put my laptop away and went to bed (different time zone).
I woke up this morning, got on Mozilla and found that my usual netVibes homepage had been replaced by a 'snap.do' homepage and that my default search engine had been switched to a 'snap.do' search engine. In a slight panic, I trawled the Internet looking for answers. Some sites suggested I remove the application 'snap.do' or Search Here - I couldn't find any such apps to uninstall. Other sites suggested processes on Firefox through which to remove the search engines - however, doing this only removes the visible part of the problem.
I tried to open Norton Antivirus, but an error message conveniently pops up whenever I try and open it (Error 8504, 104). The error message box looked fairly dodgy though, so it's obviously the virus.
I eventually downloaded a free antivirus program with 'Anvil' in the name,which I have forgotten the exact name of; and performed a full scan of my computer. Three threats were subsequently removed - however, the search engines were not. To be safe, I also restored my system to a previous backup.
Although the threats were apparently removed and my system 'restored', Norton continues to malfunction, I still have the 'Search Here' tab, and the Windows updates following the restoration failed to install. If anybody has encountered this virus, it would give me great pleasure to be rid of it once and for all. Thank you very much for any help and suggestions.
P.S. Am I able to add photos to my post, or do I need to reach a higher number of posts first? I have some screenshots of the errors I described.
Many thanks! Stephen
