My computers have been protected by anti-virus software for nearly a decade now. Originally, Dr Solomon’s but since 2003 Norton, as my latest PC came with it. I added Norton’s personal firewall when I got broadband.
I can’t say I’ve been 100 per cent happy: strange things seem to happen when you use Norton products. Now comes the coup de grace. For the last week, I’ve been unable to send and receive emails without disabling Norton anti-virus and firewall. I’ve followed the instructions given by my internet service provider, Virgin Net and the minimal advice on Norton’s website but to no avail. Given that I got the product in the first place to protect myself from email-distributed viruses, it seems crazy to have to disable its protection to receive emails!

Presumably you’ve tried rebooting the computer? I get the same thing happening at around 4pm sharp every day when Norton stops email working but rebooting tends to do the trick. Annoying though.
Jane – yes, I’ve tried rebooting but to no avail. It seems constant. I will keep trying to find a solution.
