I have recently suffered from a virus attack (despite having up to date virus software installed) which I believe entered through a weakness in IE (May have been either or both of Blaster Worm and Welchia Worm) and as a result I am having problems using the internet.
I have a broadband connection (although I also have the same problem using a dial-up connection) and whilst I can get a connection no web pages are brought up to my browser and I cannot locate my server to retrieve email. Its like I have a connection but my computer cannot see (or talk to) any other computers on the internet.
I have tried my connection on another computer and have no problems. It appears it is something to do with the setup on the problem computer. Any ideas where to start looking for problems?
