To paraphrase a recent TV commercial, we all do dumb things, but doing them with your computer doesn't have to be one of them.
Most of us know that our computers work better when they are plugged into an active electrical outlet, but ask any service technician how many times he or she has encountered that situation, and you may be surprised at the answer. Every one of us, no matter how experienced, has done at least one dumb thing with our computers. Maybe you pressed a wrong combination of keys and changed a setting you didn't mean to disturb. Maybe nothing much happened or you ended up crashing your system.
Whatever does or doesn't happen, paying attention to what you're doing combined with a dash of forethought can prevent most dumb mistakes.
David Letterman has his top ten lists. I offer my top six. My list will do little to entertain you, but it will help you to be smarter about using your system.
Dumb Computer Mistake # 6: Failing to install or keep your anti-virus and anti-spyware programs up-to-date.
Some people think that keeping these programs current is too much trouble. Others quibble because sometimes they have to disable their anti-virus program to install another application.
Don't be misguided. Viruses and spyware can gum up your system to a point where your machine can be rendered useless and inoperable. You could be a victim of fraud or risk turning your machine into a "zombie" where a third party can use your computer for criminal activities. Innocent people have been arrested and charged with downloading child pornography. They had no idea that their machines were compromised for illegal purposes, yet they found themselves in deep trouble.
Dumb Computer Mistake # 5: Indiscriminately installing freeware and shareware you find on the internet.
If you are guilty of this it's only a matter of time before you get infected with a piece of sloppily written software that will cause your system to behave erratically or crash. If you follow dumb with dumber by installing pirated software, don't ask me for help.
Dumb Computer Mistake # 4: Share your files and peripherals with the immediate world.
Turn off file and printer sharing. Unless you do this you could open your computer to access by using a public wireless hotspot with your laptop. Even if you don't use a laptop be aware that Windows, by default, has administrative sharing for the root of each drive. You can turn this feature off in the Systems Administration portion of the Control Panel.
Dumb Computer Mistake # 3: Browse through the internet without a firewall.
People new to computers are most likely to make this mistake. They tend to be entirely unaware that they need a firewall because nobody told them what a firewall is or why they need one. This lack of knowledge exposes them to every virus, worm or malicious hacker in the computer universe. Fortunately, this exposure can be easily corrected. Many modems and routers have built-in firewall protection. Personal firewalls can easily be downloaded from the web. Go to www.avast.com and download one of the best all around network security programs in existence. The best part is that this excellent program is free to the general public.
Dumb Computer Mistake # 2: Picking weak passwords.
Every hacker in the known universe understands that many people use their children's or grandchildren's name as a password. Cracking that kind of security is as easy as breathing. Don't use a family member's birthday or social security number as a password either. It's the kind of information that is all too easy to obtain. Don't create passwords from a dictionary. Hackers have programs which automatically compare passwords against dictionary entries.
Passwords should be at least 8 characters long, and be a combination of upper and lower case characters and numbers. The common objection is that they are hard to remember. That also makes them hard to crack. Create a phrase that you can easily remember and use the first letter of each word along with logical numbers. For example, "Our vacation in Jamaica begins on the fifth day of August" becomes OviJbot5do8. A password like that is impossible to guess and is not found in any dictionary.
Dumb Computer Mistake # 1: Never backing up your data or system files.
Even if you never do any other dumb thing while computing, failure to back up your data can negate everything else if you lose important information. There are too many things that can go wrong for you not to be backing up your data. Hard disk crashes, fire or water damage, tornados, hurricanes, magnetic interference, and theft are just a few of the many things that can damage or destroy data.
Backing up data can be time consuming and inconvenient, but losing your data could be catastrophic. There are many strategies you can use to protect your data, but any strategy is better than none. Don't think that merely copying your data files to an external disk constitutes backing up. Make copies of your essential data to three CDs or three sets of CDs. Keep one set at home, but in a different room than where the computer is housed. Keep another set at the office if you work for a living. If you're retired ask a friend to keep a set for you. Do the same for your friend. The third set of disks should be kept in a secure place like a safe deposit box.
Data is the only irreplaceable thing on your computer. You can replace hardware, operating systems and application software, but you can't go to a store and buy a replacement copy of your data.
The dumbest thing I can remember doing is backing up my data files to a RAM disk.
