I just installed Eset NOD32 antivirus on a Toshiba running Windows XP and it killed my connection. After 4 hours of trying to figure out what went wrong, I was able to re-establish the connection in IE and send email via Outlook Express. BUT, when I installed NOD32 again, it did the same thing... my wireless shows I'm connected to the internet, but I can't get email to send or receive, or get any web pages to come up. Any suggestions? I'd love to use this product, but if it keeps killing my connections, I can't justify spending much more time fighting with it.
