Yesterday my desktop computer running Windows XP Home kept
`freezing,' forcing me `hard-boot' it, i.e. to turn it off at the switch and then turn it on again. I could use the computer, but if I left it for a short time, when I came back I found it was `frozen'. It was as though the computer would not `wake up' from sleep mode, with the screen turned off, and not responding to the mouse or keyboard.
After a couple of hard-boots, with the same problem recurring, I decided to go into Control Panel: Power Options and set System standby and Turn off monitor to Never. But even then, when I came back after a short time from using it, I found the computer again frozen, unresponsive to the mouse or keyboard, but this time with the screen turned on and applications running.
I rang the company that I bought the computer from a couple of years ago and described the problem to a technical support person. He said right away that the cause of the problem was probably either: 1) Norton Antivirus, 2) a faulty power supply; or 3) a faulty motherboard, in that order. Then I remembered that Norton Antivirus had that morning updated itself and that the first time my computer froze was while it was running a Norton Antivirus full-system scan. So I removed Norton Antivirus in Control Panel: Add or Remove Programs and for good measure downloaded and ran the Norton Removal Tool.
I already had a copy of AVG Anti-Virus Free Edition on my laptop (which I had installed earlier in the year when I was having problems with Norton Antivirus update repeatedly saying my copy was not licensed and then deciding, correctly, that it was). I have had no problems with AVG, so I installed it also on my desktop computer and the problem of the computer freezing ceased. So the problem was Norton Antivirus. An added bonus is that Excel spreadsheets now load much faster.
There is however a downside to the free edition of AVG, which is that it does not have all the features of a paid full version. In particular, AVG Free Edition will only do scheduled full system scans, not scheduled quick scans of only key parts of a computer system as Norton Antivirus (and I presume AVG's paid edition) does. However, AVG Free Edition can still do manual scans of selected areas and the scheduled full scans run in the background and can be paused or stopped.
I have decided to share this my experience so that it might help others who have similar problems. I am not claiming that Norton Antivirus has a general problem but just that, after working fine for several years, it suddenly became a problem on my system (although the technical support person was obviously aware of similar problems on other computers). Nor am I claiming that AVG has no problems, although I am not aware of any, and this review of AVG Anti-virus Free Edition, described it as, "the best free anti-virus solution available today":
"AVG Anti-virus Free Edition, by Grisoft, is in our books, the best free anti-virus solution available today. It even out-performs many of the well-known commercial anti-virus packages in terms of effectiveness and ease of use. Its no-nonsense resident shield, low resource usage and thorough scanning engine make AVG Free Edition a must for every home user."
PS: See `tagline' quote below by Christian biologist Dr. R. Gary Chiang that what "Evolution Creation debate" and science and the Shroud of Turin have in common is, that "scientists who have based their faith in Naturalism" (i.e. nature is all there is = there is no supernatural = there is no God) "will never admit to the possibility that the Shroud could have wrapped the body of Christ," i.e. if that entails "a supernatural explanation" since "supernatural explanations are ruled out a priori by those scientists who believe that all of nature must be explained in purely materialistic terms."

"What do science and scientists have to do with the Shroud of Turin, an old piece of cloth which folklore describes as being the very linen that wrapped the body of Jesus as it laid in the tomb over 2000 years ago? According to the Roman Catholic Church, which is the current owner of this cloth, the answer is `Nothing.' Science had its chance; now it is time for scientists to leave the cloth alone. Why has the church placed a moratorium on scientific study of this cloth? Could it be that the church is afraid that modern technology will prove the Shroud a fake, and hence, seriously harm the faith of millions of Shroud believers? That is unlikely. Instead, the church has come to the very same conclusion about scientists that this book is attempting to illustrate - the prejudices of a scientist determine how that scientist interprets the scientific facts, more so than any overwhelming scientific evidence that points to one theory being more valid than another. Authorities in the church realize that science and scientists who have based their faith in Naturalism will never admit to the possibility that the Shroud could have wrapped the body of Christ. To admit to this possibility is to also support the conclusion that this cloth was touched by a God who became a real human being for a very short period of time in earth's history. That would be a supernatural explanation, and supernatural explanations are ruled out a priori by those scientists who believe that all of nature must be explained in purely materialistic terms."
