Hi Folks, Hope I am posting in the correct forum, else please direct me and I will post in the correct one. I ran MBAM on my home desktop yesterday and it found several infected objects. I quarantined all the infected objects (the list was too huge to browse through, but it had some System32 entries). After the quanrantine, I restarted my machine and it failed to boot with the message saying - Windows XP could not start because the following file is missing or corrupt: Winnt_root\System32\Hal.dll missing or corrupt: Please re-install a copy of the above file. Any help on this? The computer was running Windows XP Home Edition. Thanks Soumak
