I have a windows XP professional sp1 comp, just recently i found out i have a virus from the program mIRC, i would like to reformat because i cannot locate this file (tried many scans from this and other sites) none of which can locate this file. The other problem i have is that this computer is very old and i have no idea where the CD for this comp with the windows on it has gone. I do have a windows Media Edition cd for my other PC. I'm not sure if this would work, or there is another way to reformat without the cd. Please help me with a response. Thanks in advance.
