story so far:
my wife's friend has brought her laptop to me as she is 'unable to get on the internet'
os is vista home prem 32bit sp2, device manager says no issues with the wireless adapter or the wired adapter.
when i connect to my router using wired or wireless network & sharing centre shows me connected to router and internet. i can do a tracert to bbc.co.uk using cmd window, 8 hops, via cosh-core, glfd-bb, glfd-tmr, redb-ic to 212.58.224.138. So i guess i am connected.
launch IE,FF or chrome and i get 'unable to display', AV (Zonealarm) is unable to update.
I have run malwarebytes in safemode - picked up 4 items - worm.p2p, and removed them. run ccleaner inc registry scan. disabled Zonealarm completely and windows firewall but still no joy. restore not switched on so no restore point to go back to!
Any ideas please??
