mmm, only a little, you see im new to all of this, ive been using Gnutella for like 3-4 years, like started with napster, then KaZaA, then 2 years ago LimeWire, anyway, to asnwer your questions, the virus checker isnt really built in, the program works with your anti-virus and scans the file before completion or execution.
The IP blocks were on GnucDNA and the child mode is a mode where it only lets certain words to be used, which can be defined in word filter, it also only allows connection to G2.
umm, if you are using it at the moment post some screenshots of it like while downloading stuff, thanks!
