Thanks for all the responses, I'll go through them separately
Perhaps PHONE McAfee?
I can't access McAfee's website , US UK or any other variations (I have tried dozens of links!), so I can't get a phone number, e-mail or postal address to contact them. The only thing I have is the subscriptions e-mail address from taking out the sub. I'd be happy to phone them, but I need a number - I have tried the online directory enquiries, 192.com gave me an address in Reading, but doesn't have the number listed, neither does BT. I did e-mail the sub address last night, but no response so far. If anyone can provide a number or alternative e-mail address I'd be very grateful.
Looking at that image you posted earlier in the thread I just spotted a yellow shield in your system tray area (next to the clock, bottom right hand corner).
Was that Windows automatic updates downloading something?
The yellow shield - I've set MS to notify of downloads, but not to install automatically. Some months ago a .NET download failed & since then the yellow shield has been a fixture. (I'm assuming as this is a stand-alone PC that has never been networked I'm not missing anything important). This was also one of the ways I found out that I couldn't connect to MS - I was trying to access the updates on Wednesday as the link on the shield gave some new ones. However since the photo was taken the yellow shield disappeared & at one of the numerous re-boots we got a message that windows was installing some updates.
Today I got the yellow shield when I first switched on - clicking on it I got the message "Installing" & then %s - but no details of what was installing. I checked Task Manager - couldn't see anything other than the webpage I was on. I was rather concerned & after it had finished looked at the lists of Windows Updates etc in the Add/remove programs section of Control Panel & found none were dated today. I did wonder whether I'd get the Windows Installing message again, but didn't when I switched on again. Since then I've tried a website which had a problem apparently with Adobe 9 - as my program in the list is Adobe 8.0.1 I wonder whether there's any connection there? In the last hour the yellow shield has re-appeared & now tells me "Updates are ready for your computer. Click here to install these update" - I'm leaving well alone at the moment!
Do you have an anti-spyware program installed?
The only stuff I've got now is McAfee & Cclean - did have Ad-Aware but uninstalled it the other day (as mentioned in earlier message) - I'd tried to download updates & it got stuck & appeared corrupted - I'd had this before ages ago which I'd fixed by uninstalling & re-installing. If there's some safe download locations I can try for Ad-aware or any thing else you can recommend I'll try but I've a nasty feeling I won't be able to connect - this thing's clever!
Many thanks to all for your patience & suggestions
