Browser connectivity loss after installation

After installation I loose complete connectivity in firefox and IE as well as significant system degradation

 

If I disable the minder - I regain connectivity (and of course after I uninstall)

 

Firefox 3.5 also crashes.

 

Running an HP laptop with XP Home - Service Pack 3

1 GIG of Ram

 Avira AntiVirus

 

Thoughts?
