With so much of our personal information stored on our computers and smartphones, internet security should be a top priority. Hackers and malicious programmers have made accessing that information their priority, so knowing how to protect yourself is vital. Installing good anti-virus or malware detection software can save you many headaches.

A computer virus is a small program that, once installed on your computer, can gain access to your machine, use your computer to spread itself to other computers, interfere with the operation of your computer or perform any number of other unauthorized actions. Virus programmers are usually clever and disguise their viruses so that detection is not easy. Anti-virus software catalogs the identifying portions of these viruses, also called definitions, so they can be prevented from accessing your computer.

Detecting malicious code is much more difficult because computer users often authorize or install the malware unknowingly. Malware is often hidden in free software downloads on the internet and transmits your information or internet habits back to another malware application or to someone who plans to use your information to steal your identity or your money.

The best way to protect yourself and your computer is to install virus detection software that includes definitions for intrusive programs. Schedule a regular virus scan and set your software to update its definitions database often. Some of the best software available is easy to install, easy to use and can take care of most problems without your help.

One of the top virus-detection applications out there is BitDefender Antivirus Plus. It is an inexpensive antivirus application that you can purchase on a disc or download from the internet. Installation is quick and simple. BitDefender prioritizes your computer's resources so there is very little loss of performance during scans.

Another solid antivirus application is Kaspersky Antivirus. Kaspersky costs a bit more but has a near 100 percent detection rate for new threats. It also includes licenses for up to three users, allowing you to protect all the computers in your home with fewer purchases.

Webroot is a combination pack that uses Sophos virus detection and Spy Sweeper Antispyware to monitor your computer system. It is easy to use, offers several layers of protection and requires very little supervision to operate.

Symantec's Norton Antivirus 2012 is a new version of an old classic and keeps on providing superior detection features. Although there were past performance issues, Norton has resolved many of the conflicts it had with other software. The price is reasonable and the protection is better than much of the competition.

ESET Nod32 is another excellent antivirus application that uses heuristic detection techniques to identify new threats in addition to known or previously identified threats. It doesn't have all the features of other available antivirus software, but it is perfect for beginners and can keep up with the competition when it comes to identifying threats.

Protecting your computer means protecting your personal information and your identity. Reliable security software for your computer is like a top-notch security system in your home. Protect your valuable information and keep your computer clean.
