MBam won't delete a bad DNS cache. It might notify or pick up on a ' bad DNS entry'
Flush the DNS cache and restore MS's Hosts file... As I've posted sooo many times in this forum:
Copy and paste these lines in Note pad. @Echo on
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
Save as flush.bat
to your desktop.
Double click on the flush.bat file to run it.Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself
The problem should be resolved if you can't get your own Anti-virus program to run.
