P2P Programs like WINMX, possible to use them safely ?

The p2p programs like WINMX (winmx.com) are quite usefull. In the case of WINMX i had some blue screen deaths on win2k indicating someone nuking me (my assumption) by finding an open port. In adition to that i now have problems with other programs on win2k so i fear that someone was fiddling around with my files. I use Zonealarm wich is helpful but i think its a joke if i let people onto my PC to share files.
Is there any way to make a p2p program safe or must i forget these types of programs ?
I thought about a dedicated Linux server as firewall but a friend said that its easy to install but to set it up correctly is hard. If its not done well its not better than a win2k.
So is there some easy way to make p2p safe ?

Thanks
Peter

win 2k sp2?
latest version of zonealarm?

if you fear you are being attacked i do recomment using a dedicated  firewall.

you dont have to share any files with winMX. just point it to a directory,,, move files from them directory regulary.

enable packet filtering.
install snort if you like.

Winmx and other programs are made by people or small companies but they never show or disclose the source code..
who knows what is in these programs?

Never share the entire disk, set up a directory for sharing files as andydis pointed out, then try to do a quick search on security sites for winmx vulnerabilities, if Your problem is originated by a winmx vulnerability or "bug" NO firewall will protect You - in this case all You can do is avoid using winmx

To be more clear; if winmx needs to act as a server on the internet (ZA settings) and it exposes some port (say 8765), there could be a vulnerability; let's say that sending 512 Kb of data with a certain format to port 8765 will crash winmx, now there's nothing You can do as long as You run winmx since disabling the "internet server" check on ZA will render the program unusable but enabling it will expose You to "nukes"
