Most of the applications discussed here can continuously check websites, file downloads, and perform other activities to protect your computer and keep it safe.
How Antivirus Apps Work
The programs discussed contain a package that protects the computer from possible threats. Most often, they contain two modules - a scanner and a monitor. The scanner monitors files on request or at specified (designated) times. Its purpose is to examine the contents of the disk. The monitor, on the other hand, checks the given files continuously and automatically. It supervises the current activities of the computer.
The antivirus application analyzes the information and assesses whether there is anything to pay attention to, whether there are any threats or dangers. When choosing a algeria b2b leads computer protection program, it is worth paying attention to whether it has the ability to update new viruses. Most of the available
applications of this type have such a function. Among the modules of antivirus programs we can distinguish: scanners, monitors, vaccines, checksum programs, auto-verification programs. If there is no antivirus application installed on a given computer, and there is a sudden need to verify a disk or file - so-called online scanners can be used. To use an online scanner, you must use a web browser.
How does an antivirus program prevent viruses from entering?
checks email attachments
monitors files opened and saved on the computer
periodically scans all files available on your computer.
What happens when antivirus detects a threat
If a threat to the computer is detected, two actions take place. The first one involves passing the cleaned information to a specific interpreting system. It passes it to the system so that it can reach its destination. Then a warning is sent to the user interface.
The most important task of an antivirus application is scanning - detecting unwanted software and allowing it to be removed.
How to choose an antivirus program
The first thing to consider is whether to choose a free or paid application. There are many programs available that can be used in a free version, but most often these are poorer versions of commercial products. It is also possible to use a trial version - which costs nothing for a specified period of time, and then involves making a purchase, i.e. the so-called trial version.
The undoubted advantage of free applications is the lack of financial expenses. However, price is not the only criterion that should be considered when buying the program in question - it should be characterized primarily by high quality, ease of configuration and good opinions from other consumers. Companies should definitely value their security and choose software designed specifically for them. Companies can also buy a license for many stations, which in turn reduces costs.
Among antivirus software providers, it is worth paying attention to:
Avast! Free Antivirus; AVG Anti-Virus Free Edition (Free Apps)
Symantec, G Data, McAfee, F-Secure, Kaspersky, Eset Nod32 Antivirus (paid applications).
Advantages of using antivirus programs
The program helps prevent data loss or identity theft.
Preventing computer function impairment - infected hardware typically runs much slower.
Minimizing the risk of various types of forgery.
Safe use of e-mail.
The ability to freely browse various types of websites (if a threat is detected, the antivirus application will inform you about it).
Antivirus software also detects some spyware. However, it is worth installing a special spyware detection application on your computer.
Disadvantages of antivirus software
Programs may slow down some computers (especially during scanning).
Intrusive alerts when entering websites or downloading files can also be considered a kind of defect of antivirus applications. Nevertheless, they show how many threats we deal with on the web.
