Many people think that antivirus software and internet security program are two similar things. While they safeguard your computer and prevents it from being infected and attacked by threats, they have specific functions in terms of delivering protection and security for your computer.
Antivirus software can be installed on your computer to protect it against invaders including viruses, worms, Trojan horse and other threats. With a number of antivirus software available in the market today it is sometimes confusing which among them can offer the best protection. It is very important to select one that is equipped to provide protection from wide range of viruses and malicious software. Antivirus applications are the oldest forms of protection from viruses and malicious programs. It scans for signatures of any virus it knows. Unfortunately in the past, it cannot stop any virus it does not recognize.
But more advanced features were added such as heuristic, a method that monitors the activities of specific program and deciding if it behaves like a virus. Then it would alert the user and suggest for the best course of action. While it may not be the most accurate, it provides better security than the older method.
On the other hand, internet security is not a single program but is made up of more than one application aiming to provide the user with total protection. But its core is antivirus program. Aside from that, other applications in the suite offer more security against threats the come along with the internet age. Another application essential in it is firewall. This will restrict other people on the internet from accessing your computer or networking by denying requests and other communications from the outside and applications that run on your computer.
There are other applications that you can provide protection against spyware programs which send your personal information to entities and other types of malware.
If you are not adept into these things, an Internet Security program is an excellent choice as it combines everything that you need in a neat single package. While it is a bit expensive, the fact that it can provide you sufficient protection makes the cost well worth it. But since there are some software in the package that are worse than what you can acquire from another. For this reason, advanced users prefer to choose each application separately. Others would not require everything included in the Internet Security suite since they already have alternative solution such as Firewall.
