Pear Guardian fails to load packet filtering driver
I have been using Pear Guardian 2 on my computer since am a peer to peer user. It protects my computer just the same way a firewall does. When I run it, I get an error message as shown in the image below.
PeerGuardian is unable to load the packet filtering driver. This could happen if PeerGuardian crashed and didn’t have a chance to unload the driver, or if the pgfilter.sys can’t be found.
