Hard Disk CRASH...

This was the day which I never forget, D day starts with a horrible feeling that something is going on.. After waiking up in the morning I start my computer with internet connection, I start donwloading some stuff.. while using AVG internet security, I m from Tripura where original verson of apps are hard to find, so the internet security from AVG that I'was using uses a pirated serial number for activation & also for downloading the updates, whatever bofore D day everything was fine, but on that day I dont know why but my license expaire.. I lost the updates even my AVG I-Security fails - its DEACTIVATED! I was not infront of my PC for atleast 3 hours doing some home-stuff, So the computer running without a anti-virus for three hours with active internet connection, when I got time I came & sit, U know what I see! I saw the AVG-Inactive & the computer filled with lots lots of Virus, I immediatly re-activate AVG by using another pirated serial & shutdown the computer, thats the mistake I have done, when I restart PC in evening I found out my AVG is corrupt! It can still detect the Viruses but cant kill or heal them.. I tried with kaspersky, Avast, NOD32 & by all populer antivirus (as the publisher calling they are the best) but I f***ed up! the whole computer lots & lots virus like If I collect & burn them all I need a 700MB CD for them... ;) My whole pictures, musics, apps, games - everything acts like *.exe files, The main virus name something "Inveder.worm", I lost my 238GB of data in a minute... Even I tried with re-install of XP, but just before I install any Anti-virus the system was got infected by *.worm & *.trj from Other drvs. So there was nothing I cant do... I have to wiped out my whole 3.5 years collection of DATA... Thats the sadiest day in my whole F***ing Life...! what a mess.. what a day.. What A loss.. Now I have a whole new partioned HDD with nothing but of 238GB of EMPTY SPACES........ I still cant belive that this kind-a things happened with me..
