Just installed Avast! home edition 4.6 yesterday. Everything worked fine until I restarted. After restart I was unable to connect to the 'net. If I disconect my wireless router (Netgear 802.11g) and connect directly to the modem everything works fine, but as soon as the router is connected it kills my connection.
Athlon 2800
XP sp2
no other anti-virus running as I uninstalled the memory/process hog Norton.
