McAfee is not alone to do that.
In fact, Computer Associate (that bought the "PestPatrol" anti-spyware tool) does this too in its "eTrust" tool.

The culprit is PestPatrol, whose database of spyware signatures is notoriously outdated, and contains MANY false positive (including vital components of Windows XP's networking). PestPatrol has been completely left unmaintained for many months, probably because of lack of financial resources, which led to the company being sold and acquired by Computer Associates.

The false positive that harms LimeWire is caused by the way they detect KazaA (which is effectively a true spyware), but that cause almost all Gnutella servents to be disabled too (this includes not only LimeWire, but BearShare, GTKG or others too): they block the program names only because they share some common ports, or a handler for the Magnet protocol (that they disable too).

If you have recently updated your CA "eTrust" antivirus or security suite, and have discovered that it contained a new anti-spyware tool, you should better not enable it as it is directly based on the very bad PestPatrol signatures database (but keep its antivirus function active!), and use other more serious anti-spyware tools (Ad-Aware, Spybot Search&Destroy, SpywareBlaster), which in addition are free and supported by a large open community of users.

May be in some future, eTrust will become reliable, once CA will have cleaned up the old anti-spyware database. But for now this feature is still a beta for eTrust, and it will remain at this state for at least a full year.

It seems I spoke too soon. I had disconnected this morning and now that I'm trying to reconnect, I can't.

Every single setting is the same as it was this morning and I'm still not able to connect. It sounds like a larger issue than just a firewall at this point.

Can someone PLEASE give me instructions for Windows ME...Like a previous user has already said, the only instructions i've found have been for windows XP only....please please please, i need to know...i'm begging. It says "connecting" for like 45 seconds , but it never actually connects. Can someone please tell me of a fix for windows milenium??? pleaaaaaaaaaase

nothing is working
 

Ok I have OS X and I've tried to delete the directory and its still not working. Also, I don't have the "sharing" options in my internet preferences menu, all I have is .Mac, Network, and QuickTime options so nothing is working. I haven't been able to connect for about 2 weeks now.:(

alpha28ca, it seems that your OS is either 10.1 or 10.2 (if Jaguar didn't have a firewall). Anyway, where are you trying to connect from? Keep in mind that universities and companies tend to block P2P. Go to Limewire->Preferences->Bug Report. Click for an example and get to the part where it says "Recieved incoming this session". "False" means a firewall is prolly blocking your access. "True" is the opposite.
