Today is Personal Firewall Day. It’s not really a one-day thing, but a project. The project is to help home users understand how to protect themselves from viruses, trojans, hackers and other negative attacks as well as data loss.
It never stops amazing me that I offer classes on virus protection and avoiding data loss, and nobody signs up. Yet people lose data all the time and are surprised. I just had to reformat another friend’s computer a few days ago, because she got hit so badly (probably more than one virus or trojan) her machine would not start up. With Windows re-installed it runs perfectly. It took her since last September to realize what was up. In that period of time, her computer surely sent out messages (disguised to look like they came from someone else) that no doubt infected others she knows on the internet.
People pay me to come to their houses and fix the problems of a virus. Preventing it costs less. Here is the biggest misunderstanding: A virus checker is really two things. It is a “machine” and it is “fuel.” The machine is the program, be it Norton Antivirus or McAfee ViruScan or any other program. But a program is a dumb engine, it just checks the computer against a list to see if the things on the list are on the host machine.
The second part of the protection, the fuel, is called the data definition list or virus list. The known viruses out there change every day. In order to be protected, your engine needs the fuel which is the currently known list of viruses. If it has an old list and there is a new virus out there, you are not protected from the new virus.
When you buy a new computer or you buy a virus protection program out of a box at a store, you typically get a one-year subscription to the virus definitions. At the end of that period, your system will bring up a box (which is never written in clear English, of course) that tells you that you need to re-subscribe to the definitions. Of course, it asks for your credit card which makes most folks nervous so they tell the box no. And from that point on, their computer is not protected.
This is almost always what happens when I go to someone’s house and find a virus. They think they are protected because they “have” Norton, for example. But they merely have an engine with nearly no fuel. It is cheaper to re-subscribe than buy a new box with a virus checker, at the store. However, sometimes the method they give you for trying to pay for the new subscription is so confusing that the easiest solution is to go to the store and buy a new box, so that you can keep being protected. The box is around $55 if I remember right. (Subscriptions tend to be in the ballpark of $15Â US.) That is cheaper than hiring me by the hour to fix the problem, perhaps after losing data already.
There are other ways to lose information on your computer, of course. Remember, a computer is a machine, a gizmo. Machines break. Your machine will eventually stop running, even without a virus attack. And if that happens before you are prepared, you can lose information. There are many ways to make copies of what you do not want to lose. Some are manual processes and some can be automated. Some cost nothing, some require a computer program to “backup” the information, and some even require special equipment like a tape backup drive (it looks like a smallish cassette from a video camera).
I have a laptop and a desktop machine, connected together with wires called a network. Every night when I sleep, a program automatically starts up and copies the most important things from my laptop, to my desktop machine. This means if I take my laptop out to a client and it gets rained on or stolen, I don’t lose the important bits. I had to buy the program and had to understand how to set it up, but it works automatically and I really want that.
I have had to use my backups to restore information a few times, and it made things so that I could go on without delay. When my laptop was stolen 3 years ago, I didn’t lose a single email, not a single document. This is what I wish for everyone. No worries about data (although my heart was broken that someone would steal).
There is no time to discuss all these backup choices here. The point is to expect that your machine will stop working and make sure you don’t put your only copy of a precious digital photo or something else, on your computer’s storage (hard drive). Get it on a CD or something, so that you have at least one copy elsewhere. For text documents, printing them out is sufficient but eats space. Businesses take some of their backup materials off site, in case of a fire. Most individuals don’t find this necessary.
Sorry for the digression into seriousness. I did have a wonderful day with CityKidz Knit! I taught a 4th grader how to knit with DPNs. She was afraid it would be hard… but I told her it would only be hard if she decided it was. She ended the day saying “this is easy!” Go kid! This one took a long while to get started knitting… she had to do finger crochet and other things to build up the fine motor skills she needed. She is making up time now!
