A suggestion; in your original post, it would have helped had you stated 
what you have already done to debug the problem.  This will save 
other's time as well by not suggesting what you have already tried.

In your postings, you have not stated whether your pc is behind a NAT 
router or it's NIC is bridged to the modem's WAN iface.  In bridged 
mode, nasty things can happen if you have not secured your OS and the 
net apps.

A good sys admin practice would be to: Install aide or tripwire for 
signatures of your files systems.  Each time you upgrade/install 
anything, get a fresh sig. db. and transfer it to a "safe" place.  This 
will give an audit trail of what/when things went wrong.
