Thanks Pupudada, i have Hijackthis and i think i will post the log where it can be analysed. I am too new to analyse that log myself. just for comparison, check out the statistics now after the sp2 has been completely installed: total traffic 2MB in an an hour and 17 minutes! I have been browsing all that while. Windows firewall definitely is working now.. i got a lot of permission requests from the firewall.
