Antivirus and Firewall: What Are the Differences?

If you have installed a good antivirus and think that there is nothing to be afraid of, then in vain. It's the same with a firewall: it's not a panacea. Let's take a look at how these two main types of malware protection work.

Currently, software developers provide users with two main types of protection against computer infection: antivirus and firewalls (firewalls, firewall). Today we will figure out how they differ, what are the pros and cons of each, and how to make the right choice.

How Does It Work?

The main function of the firewall is to control incoming/outgoing traffic on the local network or the Internet. When any traffic does not meet the specified conditions, the software blocks it. Thus, this kind of program protects the computer from viruses that try to enter the system without the user's knowledge. If the user downloads the malicious file himself, then the utility will obey such actions and the Internet weed will end up in his garden.

The fundamental difference between an antivirus and a firewall is that the antivirus does not control traffic, but checks executable processes/files on the computer. It compares the results with the database developers hardwired into it. And if he sees a threat to the user, then he offers him to decide the fate of the nasty found.

Antivirus and Firewall Combo

There are also combinations consisting of antivirus + firewall in one bottle. Such complex programs provide the user with comprehensive protection but are the most "difficult" solutions for the system. The use of computer resources by such a combo set can be very high, so old people with 2-core hearts often do not cope with requests.

There are many varieties of means to combat viruses. Some antiviruses have a heuristic analysis that can detect previously unknown threats. Others know how to dig into the hidden corners of the system and get evil spirits there. Some firewalls can block ads, pop-ups, etc. The list can be continued almost indefinitely. The basic principle is as follows: for each added functionality that works in real-time, you have to pay with computer resources.

What Do You Choose?

Generally choosing between firewall and antivirus, there are several cases in which either of them will have an advantage.

If you are constantly surfing the Internet and looking into the farthest corners, then a firewall is the best choice. It will protect you from scripts on fraudulent websites that can pass traffic secretly from your eyes. In addition, it will help to combat intrusive ads and banners.

If you study, basically, the same sites, then a portable version of an antivirus that does not require installation will come in handy. Once a month, run a worm scan and clean the system. Regular scanning is a good practice, however. And even if you have a firewall, do not disdain it.

Advanced users can do without an anti-virus firewall installed. This allows you to unload the system and not be distracted by the suspicious objects found. Monthly scans and backups can solve a lot of problems. For beginners, however, it is recommended to install comprehensive protection, preferably from one manufacturer, in order to avoid software conflicts.
