Why You Need an Antivirus Program

The Internet is an amazing thing. You can go online to find out just about anything you can think of as well as talk to all your friends and download some great programs. However, there is a darker side to the Internet and that is the side of the hacker. Hackers love to create viruses and spread them across the Internet. Without an antivirus program, your computer and personal information are at risk.

A virus is a malicious program whose intentions can range from interrupting your Internet access to causing your computer to stop working and even stealing your personal information. No matter the reason for the virus, you need to be protected from them and there are a lot of different antivirus programs available for your protection.

There are some big names in antivirus protection, McAfee and Norton are the two most well known antivirus software suites; however, there are also a lot of free antivirus programs whose features and functionality are just as impressive. Most of these programs are offered for free because they also have more in-depth solutions, which you purchase.

Antivirus programs work by scanning your hard drive as well as anything coming into your system from the net against a virus database. When it detects something questionable it stops everything to deal with the threat. Most programs will have a pop up box warning you about the possible virus and ask what you want to do.

Modern antivirus programs also use a heuristic search and, simply put, this is an advanced way to look for viruses that is based on pattern recognition. Viruses tend to follow predictable layouts in their programming and through this an antivirus program can detect possible brand new viruses. This is especially important because new viruses are popping up every day.

There is no question you need to have a reliable antivirus program on your computer otherwise you are leaving your personal information open to attack or theft from a virus. A virus can be hidden in just about anything including a regular webpage and you don’t even have to download anything except for a good antivirus program.
