The scan is performed in real time, and it may take a while, depending on file size and computer configuration.
Although the software runs in the backdround, it can have little impact on system performance, but not much.

How does anti-virus software protect the system?
Antivirus software is designed to scan, detect and remove the presence of viruses on the computer system.
1. Protect the user’s computer from viruses
The main function of this software is to detect and remove viruses that cause harm to the system. Avast and Norton are two of the most popular antivirus software available on the market today.
2. Block ads and spam
Ads appear and spam emails are sent continuously is one of the signs that your device is infected. Software like Bullguard Internet Security is capable of blocking direct access to ads and websites containing malware on the computer.
3. Prevent cyber criminals from stealing data
A familiar way cybercriminals access victim computers: first send out an email containing a malicious link and a virus, trick users into clicking (or download an installation) and start spreading malicious code. Once the system is accessed, cybercriminals can delete, destroy, or even steal the victim’s data and demand ransom.
Anti-malware software like Malwarebytes performs regular scans to detect programs and “silhouettes” of cybercriminals on the computer network.
4. Speed up your computer
One of the main reasons why your PC works slowly, often freezes, hangs, … may be due to a virus. By downloading anti-virus software and installing it to prevent possible attacks.
In particular, some programs also have built-in options that allow users to delete files from unknown sources, free up hard drive space and speed up your PC to operate faster.
5. Protect the firewall from spyware
The firewall (Firewall) monitors traffic to and from the network. When combined with anti-virus software, the firewall will increase the monitoring and scrutiny of files or part of data that users send or transfer from their computer via Internet to another network.
Similarly, files and data that you receive from outside networks are more likely to include malicious links. Once you click on the link to open it, it means that you are creating opportunities for bad guys to carry out phishing attacks and steal your data and personal information.
Software like Avast comes equipped with 2-way phishing protection that blocks and deletes any email or attachment that could harm the user’s computer in any way.
6. Restricting access to some websites
Most antivirus programs have features that limit web access. This feature is designed to prevent users from visiting certain websites of unknown origin and those that contain malware.
