netscape, arena etc in root

[Antonio Rodriguez]

After installing the system from zero for the 4th time, I made the
mistake of running a few browsers as root from root, so I ended up with
a few arena. lynx and so on directories there, which I deleted thinking
contained only cache or so. Any way, now they run with trouble, i.e.,
don't run good.
1. What exactly shoud I do, and how?
Thanks,
Antonio
