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.
Any better? If so follow the guidelines in the top post of the Malware Removal forum http://www.geekstogo...uide-t2852.html
and post your logs. If not try:
Start, All Programs, Accessories, Command Prompt (Vista or Win 7 => Right click and Run As Administrator). Type with an Enter after each line in the code box:
netsh winsock reset catalog
netsh int ip reset reset.log
If it still doesn't work:
1. Click "Start," click "Control Panel," click "Network and Internet Connections," and then click "Network Connections."
2. Right-click the network connection that you want to configure (the one you use to connect to the Internet), and then click Properties.
3. On the General tab (for a local area connection), or the Networking tab (for all other connections), click "Internet Protocol (TCP/IP)", and then click "Properties."
4. Click "Use the following DNS server addresses," and then type 184.108.40.206 in the Preferred DNS server and 220.127.116.11 in the Alternate DNS server boxes.
5. Click "OK"
Reboot and test. If it still doesn't work:
(Start) Right click on My Computer, select Manage then Device Manager. Find the Network Adapters and click on the + in front to open up the sub entries. Right click on each sub-entry under Network Adapters and Uninstall. (Doesn't hurt to write down the names in case you need to download the drivers from the PC Maker's website. Normally you don't but with malware you never know.) Reboot and test.
If that doesn't help, please explain exactly how you connect to the internet (wireless or wired, router (make and model), DSL or Cable or dialup modem?)
