My internet connection is getting blocked every other minute before it comes back again. I've checked with my broadband provider and everything seems ok. I have AVG (free version) and Zone Alarm (free version). Neither picked anything up. I've just installed Spy Sweeper and it found a few adware and a trojan - topconverting downloader. It appears to have removed these. But I'm still having problems.
Can anyone help me please before I find a short plank to take a long walk off!
