I was recently infected by "Backdoor:Win32/Cycbot.B". I followed another guide here which involved first running a program called "Dr. Web" in safe mode, then another program called "Malwarebytes Anti-Malware" in normal mode. I followed the guide to the letter, and both pieces of software found many trojans and malware, etc., but the browsers still didn't work. I scanned once again with Dr. Web, and it found nothing. I used the previously mentioned thumbdrive to get software called "SuperAntiSpyware" onto the computer, installed it, and ran the full scan. I found yet more Trojands, Adware, Spyware, etc., and removed them all. The browsers still didn't work, so I ran it again, and it found nothing but a little bit of adware.
I'd prefer not to do a system restore, if I can help it, as I have not ever manually created a restore point, and I've heard from a friend that alot of software stopped working after he did a system restore.
EDIT: I have discovered that the websites that won't connect are only those starting with "www". For example: "www.google.com" and "www.gmail.com" don't work, however, "mail.google.com" does.
