Question about Windows operating system?

[closebys]

Hello Friends,

A few months ago our computer was infected by a virus and Windows XP needed to be re-installed. Now there are 2 operating systems on the computer, which the old one I do not use. Now in the hard drive there are 2 system folders: WINDOWS (Old OS) and WINDOWS1 (New OS). Can I delete the old windows system folders? If so, do I need to run any backups? All answers are appreciated....

Noooo don't touch it, I made this mistake and I couldn't boot the OS, you need to do a full clean fresh format install rather than wipe over the old on, and if you had a virus I wouldnt even dream of just re-installingm, you need a clean OS and format.

Boot from disc, format partitions, re-install.
