Computers and Technology

Home computers are a favorite target for intruders. This is because home computers are normally not very secure and are easy to attack. With high speed Internet connection, intruders can quickly find and then attack computers. Home computer security takes top priority in this context. There are several methods to secure your home computer.

Installing and using anti-virus programs is a means to protect home computers. The anti-virus program normally provides several options on how to respond, such as removing the offending patterns or destroying the file. It is advisable to keep your system patched.

Email viruses and worms are common problems. Therefore, users should be careful when reading email. A firewall program can secure your home computer. On a computer, the firewall acts as a guard, keeps the unwanted out and permits only the appropriate to enter. Backups of important files and folders must be maintained. Strong passwords must be used not only on a home computer, but also for services utilized elsewhere on the Internet. Each password should be unique and dissimilar to all other passwords. A file encryption program to access controls for very sensitive files is ideal. Those working on laptop computers should consider purchasing a commercial file encryption program.

A number of devices are used in home computer security. Computer security cables are very effective in preventing computer losses. Secure casing options are less attractive but more secure than steel cables. Audible alarms can be affixed either inside your computer or outside, and when disturbed they produce a loud siren. Disk drive locks protect drives from misuse. There are marking systems in which the computer equipment is marked with an identity mark, such as a postcode. The marking can be in different ways, in the form of tabs that are fixed with a strong epoxy adhesive or by an etching compound.

Many computer users adopt the 'it will never happen to me' policy, but there are a number of computer viruses out there just waiting to infect and destroy the information contained on their hard-drive. This is why companies invented anti-virus software, which is a program that automatically helps to detect the presence of viruses on a computer or in a file before it is opened.

Anyone who spends a considerable amount of time surfing the internet, visiting unfamiliar websites or downloading photographs is at a higher risk for computer viruses than those who do not. Computer viruses are typically attached to word processing documents, computer programs and images which, if downloaded, may instantly affect the computer's performance.

If a computer virus infects a computer, the owner may immediately lose everything in their computer and may be forced to use the factory restore disk. This CD, which is accompanied by most new computers, will restore the computer to it's original factory settings.

Anti-virus software is quite affordable considering it's wealth of use. Without it, computer users are at constant risk for computer viruses. Anti-virus software can generally be found at any computer manufacturer's website, retail store's electronic department or online at many retailers selling computers.

Anyone who suspects that their computer may be infected with a virus should refrain from sending any e-mail messages or uploading photos to family or friends. Otherwise, the virus may spread to infect their computers as well.

Anti-virus software is available most commonly on a CD-Rom, but may also be downloaded from some manufacturers. By double clicking on the software, the anti-virus program will begin to perform a scan of your entire computer. As it progresses, it will give you an update on any potential located viruses or files that may be of concern. In addition, some anti-virus software will allow users to scan a single file before opening it. For example, if a computer user were to download an image but wanted to run a virus scan on it prior to opening the file, he/she could click on the anti-virus software and direct it toward the file in question. The anti-virus program would scan the file for potential viruses and will post the results immediately on the computer screen. This will allow the computer user to know which files are safe and which are not.

In today's world, anti-virus software is to computers as Tylenol is to headaches. It's both a preventative approach and a cure for certain ailments affecting a computer. If a user does not have anti-virus software pre-installed into their computer, it is recommended that they purchase a program immediately before logging on to the internet.
