Hello,
I hope this is the right forum for this question. I am sorry to bother you all but I've been working on my computer all day. It is a windows XP machine that has a virus. I made a knoppix live cd to boot with. I ran a f-prot virus scan and it found viruses but didnt clean them because I didnt have write permission set. It was in read only. That is what wasted most of the day.

I followed more instructions to mount the drive which is located at /dev/hda1 then I right clicked to change read/write permission but it says "the command failed, maybe there is another process accessing the file system".
