I finally got broadband yesterday from TalkTalk. On the CD you get a free trial for firewall and so on (you have to start paying after a while). I didn't want to do this since I knew I could get Sygate's free firewall as soon as I was online...
... BIG mistake. The MOMENT the system connected a flood of crap started arriving. On my 2.2Mbps connection I was downloading the firewall at about 4K per second, purely because the connection was being saturated by rubbish - .exes started appearing and popups all over the place; the whole PC slowed to a crawl.
Luckily i have a 2nd PC using dialup which already has a firewall. I installed the broadband on this PC and was able to dowload the firewall installer at 200K per second and then copy it to the first PC.
But my concern is, how did the adware find the PC so fast. My dialup PC lasted ages with no protection until one day it got 'found'. I wondered if my broadband IP had somehow been broadcast - is this likely? Perhaps TalkTalk want to show how much you need protection software by ensuring you get attacked?
