When i connect to the internet on my other pc, the computer turns off as soon as its made a connection, Im using windows xp sp1 and avg antivirus with zonealarm pro firewall, ive never had the problem before and i cant think of anything ive done to create it. I feel it may be a worm or virus bus my viri checker wont find it, im unable to update it because i cant connect to the net. im on dial up with both pc's and use the same account so its not the isp. Im not sure but feel its somthing to do with the kernel32.dll file, what does this dynamic link libary file actually do? im unable to read the source code because its encrypted. please try to help. thanks in advance.
