Thank you for your replies, I`ve tried 3 P2P known programs, 2 of them were infesting my PC over and over again (scanned them before opening trial). The files download was very fast and ....with a lot of "goodies" in it , mind you these were not crackers or some other questionable stuff...
The one that was clean as a whistle although much slower, was e Mule, with about a week of downloading without even one detected malware, against a full load of detections with the others.
So I guess I`ll be better safe than sorry...
