On one of computers in my organization I got a strange problem. After nod32 3.0 was installed, after some time of work (usually 30 min-1 hour) computer gets problem with access to email, internet etc. All servers pings ok, but if you want to get email or browse internet it is an access error. When computer restarted, it again works ok for some time, then problem comes back. It is clearly somehow related to NOD32, because if I uninstall it problem gone. Any ideas?
