Thank you all for your comments. I use McAfee and have deleted and reinstalled it and there is still a problem. When I set it to scan automatically, it crashes, but not usually when I scan it manually.
I have used the restore point but I have had problems for quite a long time and even going back a month has not helped. My computer man deleted conflicting malaware software before I deleted and reinstalled the latest McAfee. He thinks it is a hard drive or memory problem, but it may be more economical to get a new computer.
Unfortunately I understand Windows 7 will not support Outlook Express, so we cannot import our old emails to our new machines.
I also understand that with Windows 7, one needs a wireless router and at present for Windows XP we have a modem (with cables all over our home). Is there a way of using both computers, using our Tiscali/Talktalk provider?
Can I look up old emails on old computer, if needed, but send and receive on new computer. Do both PCs have to be physically linked; do I need two modems into wall sockets or what?
Any advice or help would be gratefully received. We need old system as my partner and I are unemployed and need our computer to job hunt/receive job alerts. Also I have a lot of ancestry research details on my Outlook Express emails, which I do not want to lose.
Thanks.
