Does System Restore occasionally solve viruses?

Hi, so I got a virus, when I accessed a website, and something was added to my Roaming folder. I immediately ended the process it started in task manager, and deleted the folder, but afterwards my computer lost its firewall and Microsoft Security Essentials went kablooey. After completely screwing up my computer using all this antivirus and virus deletion software (I scanned multiple times, It found the virus and *said* it deleted it, but another scan again would say otherwise. So after I screwed up my computer to the point that it wouldn't go into the loading screen for Windows, I did a System Restore.

I restored back 4 days before the virus incident had been downloaded, and despite people saying system restore won't fix it, my internet is back online, and I'm having no problems. Firewall and Windows update is back and working, and even Microsoft Security Essentials is back online. I'm scanning for viruses right now, so I want an honest opinion from T.H, and if you guys have a proper virus deletion thing that will actually delete it, not to come back several minutes later. Also, how do I stop websites automatically downloading things to my roaming folder (%appdata%)?
 
Yes system restore will remove a virus completely. However most viruses disable system restore by deleting previous restore points so this method rarely works. Malwarebytes is the best anti-virus software at actually removing viruses in my experience and you can download the free version which is not resident for this purpose.

I think the reason it worked was because I actually system restored it BEFORE I logged on because I screwed up my computer. It gave me the option to system restore, and I didn't try it at first because when I was at desktop it didn't work, and there was an error code. Many thanks! I'll try get other people's opinions as well.

Ok, Area51, would anything cause it to re start itself? I'm running Security Essentials, and later ill run malwarebytes which I used previously before Restoring it, as deletion of the viruses just meant they came back on restart of the computer.

Well thankgod I didn't get that. What turned out for me thinking it was just 1 virus, it was several malware and trojans as well, so I'm guessing the first virus opened the floodgates for the rest of the viruses or something.
