What usually happens is the malware sets up a proxy on your computer. Then it forces IE or Firefox to send all traffic going to the internet to the proxy. Since it's a malware proxy it picks and chooses what goes to the internet and keeps you from going to certain anti-malware sites and perhaps sends copies of interesting traffic like passwords and credit cards to another address for harvesting. MBAM or your anti-malware software knows the proxy software is malware so removes it but doesn't realize that it's also a proxy so doesn't change the proxy settings on IE and FF. So now IE or Firefox still sends traffic to the proxy but there is no proxy so it doesn't go anywhere and you have lost connectivity to the internet.
To fix it:
In IE, Tools, Internet Options, Connections, LAN Settings, then uncheck all boxes and OK. Close IE and restart IE.
In FireFox, Tools, Options, Advanced, Settings, check No Proxy then OK. Close Firefox and restart Firefox.
In Chrome, Wrench, Options, Under the Hood, Change Proxy Settings, uncheck all boxes, OK.
