I am FRUSTRATED!!! What is wrong????

Hi, All you "geeks" out there!

I am getting so frustrated with all the "stuff" going on with me trying to open pages ("Sorry! This page cannot be found" messages!)--this sometimes even includes my Home Page or trying to open a DG link in a Post--or if I am trying to open a hyperlink to something. This seems to occur more often in the morning of the day. Are the circuits more busy then???
Sometimes I opt to restart my computer, but that takes about 15 minutes to get back to "normal". That is ANOTHER problem.......

E-mails from people, whose addresses I have always had in my address book, are now coming up in my Suspect Spam folder. Like my daughters!!! They still have the same e-mail addresses, BUT--their e-mails, sometimes, are directed to my Suspect Spam folder!!! WHY???? I always click on "add to my address book and send to my inbox", and then--the next time they write me, it still is requesting permission to be added to my e-mail. What is going on?????

Regular "newsletters" I have gotten for ages, and have many times clicked on the "add to my address book and send to my inbox"--still, every time I get them, get sent to the "suspect" folder. I am glad I check it every day, or they would get automatically deleted.

For those of you that will ask the obvious...........

I have Earthling2000 professional as my server. I have Norton Systemworks protecting everything ....I hope!
I have Zone alarm and I have Spam blocker (known Spam and Suspect Spam--set on "high"). I have automatic updates and "One Button Check-Up" running on a regular basis. I have run my "Spybot Search and Destroy" regularly and keep deleting my Temporary Files.

Here are some other "weird" things going on.
If Norton wants to do an update, I have to shut off my Zone Alarm, or it cannot "Open the Program". Does the fact that they are next to each other in my bottom tool-bar have anything to do with it? Someone suggested that??? When it is done, I have to re-activate my Zone Alarm.

If there has been an automatic "Button checkup", I have to sign in all over again in my Home page and my Daves Garden web page that I live on. WHY does it not stay signed on?

Here's a really BIG weird thing!!! Sometimes, for NO reason that I am aware of, my Nortom System Works is deactivated. I only know this if I look down in the bottom task bar and there is a red "x" on my Norton Anti-Virus icon. Then, I have to reactivate it.

Does any of this give you more expert people some kind of a pattern of what is wrong?
I guess I could call Earthlink Support and talk to someone in India, but I thought I would ask the local experts first so I can understand your suggestions.

Thanks for any light you can shed on this ongoing prolem,

Gita
