When you purchase a PC almost every unit comes with an antivirus program preinstalled to provide protection against viruses and malware. Most of the antivirus programs that are installed on PCs are reputable however, it is important to note that an antivirus program is only as efficient as its capability to provide antivirus definition updates.
Although you do not have to be tech savvy to determine the quality of an antivirus program it does help to understand a little about antivirus definitions, how the updates work, and why they are important. Here is some background information to help you determine how much an antivirus program will be capable of protecting your PC.
Antivirus Definition Databases
Viruses are created using a programming code which is known as a signature. New viruses and threats are released on a daily basis which is a primary reason why definition updates are important.
Most antivirus definition databases are updated with the latest viruses on a daily basis. The higher quality databases are comprehensive which means that they contain the largest number of virus definitions that are updated on a daily basis. Other databases are not as comprehensive and do not update as often.
Antivirus Definition Updates
The higher quality antivirus programs are connected with definition databases that are comprehensive and are updated on a daily basis. When you update your antivirus program the latest definitions are loaded into the program which provides better virus protection for your PC.
If a virus is present on your PC, being connected with a quality definition database means that the antivirus program will be more capable of identifying and removing the virus. If the definition database is not complete when you update your antivirus program from the database, there is a larger possibility that a virus which is present in your computer will go undetected by the antivirus program.
Antivirus Update Methods
Quality antivirus programs will use a variety of approaches for detecting the presence of viruses on your PC. One approach involves identification of the virus by signature which means the antivirus software detects a possible virus on your PC and then compares it with a virus signature from the database. If there is a match, then the software proceeds to quarantine the virus before removing it from your PC.
Another approach involves identification of any type of behavior in your PC that looks potentially dangerous and may pose a risk to your PC. This is known as heuristic identification and monitors the behavior of all of the programs on your PC for any suspicious activity. If a program is launched in your PC’s operating system the antivirus program will log the activity of the program to determine whether or not it is a threat to your PC.
Hopefully this information will provide you with a general understanding of how antivirus definition updates work, why they are important, and how they determine the quality of an antivirus program.
