Nah... I have reinstalled all the patches since and I can surf fine. I suspect a spammer used my IP once. One of the 2 sites that banned me has unbanned me without me asking anything - prolly a temporary ban. The other site still has me banned - I could always ask the webmaster to be unbanned, but it's not like a very important site.
Plus, it's useful. I'm using it now as a test bed for playing with proxies. And gee, do proxies suck. Most of the time they are slow and time out a lot. And they often don't last long. One has to get a new one - and thus testing it for workability all over again - every day.
