Because of the OS design, newsbin can't possibly directly cause the connection to break, it simply doesn't have the permission to interfere with it directly. It asks the OS for something, it responds back with the results. Newsbin can't somehow demand the entire network connection and lock out everything else. It might demand a *lot*, but all it can do is ask for things, like every other application.
Now, having said that, it is possible that newsbin can cause enough stress on your network infrastructure to make it break indirectly - for example if you're pushing hard over a wifi connection, your router simply may not be able to handle that and resets/locks up. The deleting of downloaded files having any impact at all on whether your browser works sounds dubious, I must say. Same with newsbin continuing to work but the network is broken(unless you just mean it's injecting already-downloaded headers into the database). All in all there's too many conflicting sounding symptoms here, I think one step at a time is useful.
Overall, it sounds like something in the network, or perhaps on your system, is fragile or broken. Things to try:
1. My favourite and constant mantra: completely disable any and all 3rd party antivirus or firewall and see if that makes a difference. AVs are insidious.
2. Don't download over wifi(you don't mention, or I missed it)
3. Try bypassing your router(not always possible). It might be having a problem when network stress gets high.
4. Try running with just a couple of connections - the point being to see if it's the speed that's related to the problem.
5. When a problem consistently happens after a certain volume is downloaded, that sometimes can be related to your ISP. They cap you after a certain initial volume. Not my first guess - this is highly unlikely to cause a network *crash*, but the volume before a problem thing might be a clue.
