Sorry this is complicated but I’ll try to be brief.

About 4 weeks ago I restored my computer to an earlier date , this resulted in the loss of McAfee Security & the need to re-install my virus protection.
I could not re-install McAfee because my Dial-Up connection was beyond slow & repeatedly dropped the connection.
At around the same time Internet Explorer 8 was installed , not sure of the exact date , but I think it was after the problems first started.
So I took my computer to the local Internet Café & re-installed McAfee using their broadband connection (same ISP) the owner set it up so quickly I don‘t know which settings he changed , but I noticed he reset Internet Explorer to the default settings.
I later discovered that about this time my ISP had suffered “Cache Poisoning ” attacks on two occasions , resulting in service disruption over a period of 2 weeks.
Since all this happened I’ve had escalating problems with my computer system as detailed below:

1) Non - communication between my Dial-Up connection , Internet Explorer & Outlook Express.
I have been able to re-set my custom configuration for browsing & email but my settings keep reverting back to non-communication status.

2) My “Paint” program (which I use a lot) is now un-useable & reports the following:
“There is not enough Memory or Resources to complete operation.
Close some programs & then try again”
N.B. No other programs were open at the time

3) Computer performance has become exceptionally slow & is frequently freezing.

McAfee Security is up to date & no threats have been detected.
I have performed a “Quick Clean” & apparently I do not need to perform a disc de-frag.
I have also checked my Modem , Network Connections & other areas I thought might be causing the problem using “Help & Support” … no problems were reported (as far as my untrained eye can tell).
By the way this is my personal computer & no-one else uses it.

Can someone please advise me what I need to do to sort this out , bearing in mind that I am not at all technically knowledgeable.

Thank you for your patience in reading my long tale of woe !
