If the PC is running slowly then swap to an ethernet connected router - TW were doing an offer of a free wireless router to new and existing customers although I think it's on hold at the moment because of issues with the firmware interface and IE7.

The USB connected modem will still suffer from the same security problems as a direct ethernet connection - the PC is still presented with the same network packets as the end result.

From a performance perspective there are two things:
1. USB uses much more CPU overhead than a direct ethernet stream.
2. Assuming the PC does have a firewall that is going to have to do a lot more work with all of the extra junk received at the modem, again chewing up CPU time. Getting a router removes that workload.

This won't fix all of your problems, but it's a start.
