Understanding and Preventing Computer Viruses

When it comes to threats to computers, the computer virus is very serious. Computer viruses can have ramifications that affect many aspects of your computer use, as well as creating a number of security risks.

A computer virus is a term used to describe a type of software that executes malicious code on your computer. There are many types of computer viruses. Some computer viruses are designed to serve advertisements on the affected computer, some steal information that the users types, such as user names and passwords, and some send spam email and are used as bots to attack other computer systems.

One of the most common types of viruses is the scare-ware virus, which refers to a type of computer virus that informs locks the user’s computer down and informs them that the computer has been infected. Then, they present the option to buy their own “anti-virus software,” which in many cases doesn’t even reverse the damage they have done.

Since computer viruses are so very serious and can result in stolen identities and other personal information loss, it is very important to take measures to prevent them.

The first step should involve using an anti-virus software, which will use a database of known threats to scan the computer and files that are in-use, as well as downloads. Most quality anti-virus software will also perform a Heuristic analysis, which is a special check designed to analyze new files, so that unknown threats can be detected.

However, using an anti-virus alone will not always prevent viruses. It is very important to be conscious about what websites you visit and emails you view. There is a saying that a computer is only as smart as the person behind it and in many cases, virus makers count on being able to fool the user. There are a number of scams, which often involve forging email addresses from well known businesses and then attempting to get people to open attached files.

It is also common to see images and banner ads that indicate that a computer is infected or that the user needs to perform a virus check, with these linking to malicious pages that can infect the computer.

In addition to being cautious, it is also very important to turn on automatic updates. Whether you use Windows, Linux, or Mac OSX, viruses can affect your system through un-patched security holes. This is true not only of your computer’s operating system, but also individual software like your web browser, Adobe Flash Player, and Adobe Reader. The last two products by Adobe, Reader and Flash Player, are very commonly exploited.

Many vendors, like Microsoft, actively update their software on a regular basis, so it is important to regularly check for and download updates. Generally, once an update has been released, the issue is known widely and will then be exploited by virus makers.

While viruses are very serious, by maintaining a multi-pronged defense system, which involves keeping your software updated, being very conscious about what types of websites and emails you view, and using a quality anti-virus software, most threats can be largely minimized.
