hi,
i am sorry to hear that,but i think that your harddisk is damage from that resistence virus !!
I guess you need to buy a new harddisk and install everything again or maybe you can do one thing.....
is your pc always direct connected or not?
if it is,you must first plug your modem off from your pc and try then a rebootscan first,and later when xp is running a thorough scan,i don't know if it will work but you must tryn everything before you buy another HD is it??
see ya,
Micho.
