today all sorts of crazy crap started happening in windowsXP, first off \nthe (default) firewall stopped working, and other probs, including AVG \nupdater won't work and reports bad install.\n\ntrying to enable the firewall reports:\n"firewall settings cannot be displayed because the assocaited service is \nnot running. do you want to enable the firewall/ics?"\n\nclicking yes just reports "can't enable firewall/ics". (yay!).\n\nwhen i right click on my computer\n"the application or DLL C:\windows\system32\esent.dll is not a valid \nwindows image. please check this against your installation date."\n\nwhat the hell does that mean...?? it is a legitimate windows licence, \nabout 2 months old. i did a full virus scan with AVG and couldn't find \nanything.\n\n?
