Hvordan fungerer antivirus?

With cyberthreats becoming more clever and aggressive over time, Antivirus software has become an essential tool for online protection. This article will explore how antivirus software works, how it detects threats and the common misconceptions people may have.

Hva er antivirusprogramvare?

Antivirus software is a program designed to detect, prevent, and remove malicious software, also known as malware. Malware includes viruses, spyware, ransomware, and other harmful programs that can compromise your data or disrupt your device’s performance.

The primary purpose of antivirus software is to identify a threat, quarantine and remove, before it can access your computer or cell device.

Grunnleggende: Hvordan antivirusprogramvare oppdager trusler

Once installed, antivirus software works by scanning files, programs, and websites to identify potential threats. You can choose to have the software automatically run in the background, and detect threats in real-time, which is the advised setup. Real-time scanning ensures threats are detected and blocked immediately, before they can cause harm. Or you can choose to run security scans as and when you want to.

Modern antivirus solutions go beyond basic virus detection, offering comprehensive protection against ever-evolving online threats. Antivirus software checks against an existing database of known viruses, whilst also using an advanced machine learning technique to detect new and emerging cyberattacks.

Hvordan antivirusprogramvare fjerner trusler

Når en trussel er oppdaget, går antivirusprogrammet gjennom følgende trinn:

Karantene - Den ondsinnede filen isoleres for å forhindre at den sprer seg eller forårsaker ytterligere skade.
Fjerning - The infected file is deleted from your system and placed in a hidden folder so other programs can’t access it.
Varsling - Antivirusprogrammet varsler deg om den oppdagede trusselen, og gir deg informasjon om type og alvorlighetsgrad.
