I have recently ran the freeware version of avast. After running a quick scan it recommended I do a boot scan. I must have allowed it to delete a file I shouldn't have, because since running I can no longer connect to the internet or my router. The system cannot get an IP address and even when I manually set the IP it still will not connect. Any help would be appreciated or else I am going to have to purchase Windows 7 and kill my xp install.
