3. How does antivirus software work?

 Antivirus software acts as an important layer of defense for your computers and mobile devices, helping to detect, block, and remove malware. Here's how antivirus software works:

3.1. Scan and detect

Antivirus software scans your system for malicious files and code. This usually happens in two ways:Real-time scanning: The software automatically scans all files and applications as they are opened or downloaded, to detect threats immediately.
Periodic Scans: Users can schedule full system scans to ensure no malicious files are missed.

3.2. Comparison with virus database

Antivirus software uses a large database of known viruses. When it scans, it compares files to virus patterns in this database. If a match is found, the software identifies the file as malicious.

3.3. Identifying suspicious behavior

In addition to comparing against virus samples, many modern antivirus software also use behavioral recognition technology to detect unusual file actions. If a file tries to perform virus-like actions (for example, copying itself or overwriting system files), the software will warn and block this action.

3.4. Isolation and removal

When malware is detected, the antivirus software moves the file into quarantine, where it cannot cause harm to the system. The user can review it and decide whether to delete or restore the file.

3.5. Network Traffic Monitoring

Some antivirus software also has the ability to monitor network traffic to detect any suspicious activity, such as the transmission of data out without the user's permission.
