Hey all,

Got infected with Antivirus Suite recently, used malwarebytes (in safe mode) which found and removed several infected files, then said that a restart was necessary to completely remove the infections. Upon restart, Local Area Connection is stuck on "acquiring IP address" and never connects.

Booted up with Ubuntu Live CD and was able to connect to internet, so the problem is definitely virus-related.

Any ideas? Thanks in advance...

Yeah I've done all that. My symptom is not typical of the antivirus suite virus (AFAIK) - it is not the typical IE proxy setting issue, but rather a problem with LAN.

Hi Daedalus, click Start > Run, type services.msc and press enter.

Scroll down to the DHCP Service and check that it is started. If not, please start it and let me know what happens. If you get any error message, please list it in a next reply.

regards, Elise

Let's see if flushing your DNS cache and restoring MS's Hosts file helps:

Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0


Save as flush.bat to your desktop.
Double click on the flush.bat file to run it. Your computer will reboot itself.

** If running Vista or Windows 7, right click on the batch file and choose to run as Administrator.
