Firstly - thanks for advice on cleaning out Lycos sidebar & Adware! Next problem...
Since installing SP2 I cannot download anything. This is now getting worrying because of course Symantec is continually reminding me about updating virus definitions but this never works. Also, cannot download Microsoft Windows updates.
When I try to download the regular graphic comes up (the "flying file") but progress bar does not action. When trying to download Symantec updates it recognises the updates I need, starts to download that stops. I have followed the Symantec advise page on this with no luck.
