Configuring firewall

lukaswrites · 14 Apr 2010

hi guys, recently i have been attacked by a new kind of virus which couldn't be handled by any antivirus in this world, even i have submitted the suspicious file to microsoft, they said that it's not a malware, the virus has 'injected' some codes or libraries into a process called 'svchost.exe' and as we know, svchost controls whole networking system in windows 7.

Also, after took over the network, this virus trying to donwload and access some files over the net ( i believe that the files are the real malware) Question is how can i configure windows firewall so that it will block any programs which trying to access an unknown website? Note : the virus also gains access to the web through all of my web browser-firefox,opera,IE,chrome , it means that they all have been 'injected' too. please help

You can set up your firewall to only let access to trusted websites, but that list is going to be so long that it'll take forever to set it up. You could do it on demand, i.e. allowing requests individually but then you'd have to differentiate between bad and good requests. What you should really do is clean install. Since you're infected and none of the av programs are picking it up you can't rely on any backups.

Just format and start over, it sucks but if you're actually infected with no way to identify the corrupted files you have to just get rid of everything.
