Per your oft-repeated recommendation, I downloaded and installed Grisoft AVG anti-virus. I disabled Norton's anti-virus program. My computer works fine on Internet applications, but Outlook Express won't connect.
Also, the computer won't always respond to commands. I removed AVG, enabled Norton and am back to normal. Any idea how to make AVG work?
Also, you say in a recent column that XP has a backup program. I can't find it.

Let's start with your anti-virus problem. Simply disabling Norton's anti-virus isn't enough. You need to totally remove the program for Grisoft's AVG to work properly. Two virus programs seldom get along.
As far as the backup problem: Windows Vista installs its backup program when you install Vista. With XP, the backup program is on the CD but has to be installed separately. It doesn't install automatically.
Here's the Microsoft Web site that explains how to set up the backup program for XP: www.microsoft.com/windowsxp/using/setup/ learnmore/bott-03july14.mspx .
I read your recent column about computer maintenance. There are a few things I would like to add, based on having been in electronics maintenance since 1964.
I recommend that computer owners who buy the air cans used to clean dust from a computer get the ones that come with a plastic nozzle extension. That way, the static electricity danger you mentioned would be eliminated.
What you said about dust harming electronic circuits is true. The dust that circulates through the area of the circuits will be attracted because of the static electricity present. Once lodged in the circuit card, the dust will also attract and retain moisture, which is always present in the air.
The moisture will build up until it will cause a short and possibly create a spark.
If there is a smoker present in the computer's home, the tar in the smoke will build up in the circuits, too.

Those are good tips. Thank you. As far as smoke, you're right. When I look at ads for used ham radio equipment, the ad will often mention that it was owned by a nonsmoker.
