What comes to mind when you are thinking about a powerful and handy antivirus program? A well-known name and brand? A trusted and reliable service? A wide array of features? The simplicity in operating or managing the task? When it comes to choosing the right antivirus, things can be complicated and confusing. You need to realize that there is no such a thing as a perfect antivirus. The right antivirus exists but it depends on personal preference and needs. That’s why you need to understand the basic function of such a program before making a decision.
The Functions of an Antivirus
Basically, the antivirus program will be your first defense against threats and attacks. If you have a solid and very good antivirus, then you won’t have to worry about a thing. The program basically will filter out everything that comes to your computer. It will filter the contents and track the sources, and then it will record the data. All the information will be collected inside the database to make sorting out process easier.
The program will monitor your computer system all the time – basically 24/7. If there is something suspicious (whether it is an activity or a file), then the program will filter it out, record the data, and keep it in the database. It will index the suspicious file or folder, catalog it, and store the information. Once it is kept in the database, it will set up the basic info for further activities. When it is updated, you can get the most benefits out of it.
There are two major operational types of the antivirus: the active one and the passive one. Passive antivirus requires the users to perform the manual scan or have a scheduled checking of the virus. The active one runs automatically. It usually detects in a real-time manner and immediately fights threats.
Virus Handle and Treatment
In most cases, the antivirus program will have 3 basic options when it finds any suspicious activity or files.
- Deletion. In most cases, antivirus software will automatically delete the file. After all, deleting it will be the best choice because you generally remove the threat for once and for all. However, some viruses are pretty ‘clever’ and they make themselves unable to be deleted. If this happens to you, then your only option is the second one.
- Quarantine. The antivirus software will quarantine the virus –separating it from the others. By isolating the threat, it is expected that the file or folder won’t be able to spread and infect other files. By isolating it, it is expected that further damage can be prevented or at least minimized.
- Ignorance. This is the least favorable option because your antivirus will basically do nothing. Such a program usually tries to come up with a solution first. But when it is helpless, it simply ignores the threat. Such a thing can also happen when the antivirus is pretty weak and lame.
This is a common thing that usually happens in the antivirus program. Such a program like Smadav can provide an extra benefit, especially if you want to scan external devices. It doesn’t hurt to use an additional antivirus program besides the main one.
