Step 6: Keep Viruses at Bay


What is a virus?

A computer virus is a program that can make copies of itself. Most computer viruses do nothing more than this and are more of an annoyance than a danger. Some computer viruses, though, may also harm data and programs stored on a computer.

What types of viruses are there?PC VIRUS

  • Program viruses infect computer programs and become active when the infected program is run. 
  • Boot sector viruses infect diskettes and hard disks and become active when an infected disk is used to start the computer. (On a Macintosh, merely inserting an infected disk can activate a virus.) 
  • Macro viruses infect documents (files) through the macro programming capabilities of some newer programs. Macro viruses become active when an infected document is opened, and the program opening the document has its macro capabilities turned on (enabled).What is not a virus?

Trojan horse programs are designed to do something (usually something malicious) other than their supposed purpose. Trojan horse programs are sometimes classified with viruses. However, because they don’t make copies of themselves, they are not true viruses.

 

Some programs are designed as a joke, or prank, but are not viruses. For instance, warnings of a virus incorporated in a mail message with the phrase “Good Times,” “Join the Crew,” or “Penpal Greetings” in the header have, at times, been rampant. The only thing that spreads, however, with these “viruses,” is the messages warning people to look out for the supposed virus in their e-mail. And, it’s the person sending the message, not the computer, that causes the message to be copied and spread.

Step 5: Back up your Data

Backup ImageBacking up your files simply means making a copy of them so that if the original is lost or damaged, you can use the copy. You can back up your hard disk to floppies, to a Zip disk, or to a tape drive. For under $100.00 you can purchase an external drive to do all you backups. There are many backup programs to use so select your software carefully.

 

How often you back up depends on how valuable your time is. If you’re working on an important file, save it to a floppy as well as to your hard disk. If you’re running a home-based business, you should invest in a tape backup drive and back up on a daily basis.

 

Most families can get by with a less rigorous backup schedule. Back up the files in your data folders (see Step 4) once a week, and perform a complete system backup every six months. You can back up your data files simply by dragging their folders to the icon for your floppy disk, CD or DVD.

 

If you’re a Windows 95/98/ME/2000/XP/Vista user, you can use the Backup program in Programs/Accessories/System tools. This lets you check off the folders you want to back up.

 

High-capacity removable disks, such as those DVD’s, are great for backing up a hard disk, and they can help keep down the clutter on your disk. A tape drive that can store from 400MB to 2GB of data is even better for backup, as it will keep media-swapping to a minimum. All tape drives also come with their own backup software.

 

For centuries patients have tried all sorts of medicines for erectile dysfunction – the repeated inability to maintain an erection firm enough for sexual intercourse. Sought-after are remedies which are used to reduce fever caused by inflammation of the skeletal muscle etc. Sometimes folk need remedies to resolution sexual disfunction.

All kinds of remedies, from those that are elaborate ‘all natural’ to those that are chemically produced in a laboratory, carry some dangerous side effects. Preparatory to using the treatment, tell your dispenser if you are allergic to anything.

Step 4: Store with a Plan

You have lots of reasons to keep the files on your hard disk organized.

 

First, it makes it easier to do “housecleaning” — deleting files you no longer need.

 

Second, keeping data files in their own well-labeled folders reduces the risk that you will inadvertently delete an important program or data file.

 

Finally, a well-organized hard drive is easier and faster to back up.

 

Create folders for each program and place only the appropriate data files in them.

 

Alternately, create folders for each member of the family. Give files and folders names that will make sense even after you’ve forgotten why you created them.

 

In addition to organizing your files, at least every two months you should delete files you no longer need. A disk filled to within 5 percent of capacity is more prone to errors — and a lot slower — than one that is not so chock-full.

Step 3:Tune Your Hard Disk Regularly

Because it is the place where you permanently store your applications and, more important, the data files you create with those applications, your hard disk requires special attention to keep it operating at peak efficiency. Disk scans for “lost” files and bad sectors will prevent most disk problems before they occur, while running a DISK DEFRAGMENTATION utility will improve the performance of your system.

 

Every day, you create new files, delete unwanted ones, and write updated versions of current files to your computer’s hard disk. Because of the way Windows and the Mac OS assign disk space to files, your hard disk can become fragmented over time (i.e., your files get placed in pieces all over the hard disk, because there is no contiguous space large enough to hold them). A fragmented hard disk slows disk access and makes it harder to recover from disk errors.

 

To DEFRAGEMENT a Windows 95/98/ME/XP/Vista hard disk, use the Disk Defragmenter program in Programs/Accessories/System Tools. On a Mac, use a utility such as the Speed Disk tool that comes with Norton Utilities for the Macintosh. You should defrag your hard disk every six months. You should also defrag it after you have created or deleted a lot of files in a short span of time.

 

Occasionally, a storage area called a sector on your hard disk goes bad. A utility called a disk scanner detects such “hard” errors and keeps a table of such sectors so that your operating system doesn’t try to use them to store files. In addition, a disk scanner detects “soft” errors, where the operating system has lost track of pieces of one or more files. ScanDisk (found in Programs/Accessories/System tools) is Windows 95/98/ME/XP built-in disk scanner, and it detects both hard and soft errors.

 

On the Mac, you can use the Disk First Aid program that comes with your system or the more powerful Disk Doctor utility included in the ubiquitous Norton Utilities for Macintosh. You should run a hard disk scan at least every month. In addition, if your computer crashes or you accidentally shut down without going through the proper shutdown procedure, run a disk scan as soon as you reboot.
