How Does Antivirus Offer Protection?
Via scanning and detection. These are the two main techniques which antivirus(es) heavily rely on to protect PC(s). They keep scanning the systems constantly in the background, looking for malware existence, as PC users go about doing their activities. Modern-day antiviruses are so good that they don't even slow down the system or affect its performance in any way.
Types of Virus Scanning
- On Access Scans
- Full System Scans
Antivirus software typically scans PC(s) in two different ways: via on-access scans and full system scans. Full system scans are usually performed when antivirus is first installed on PC(s). Whereas on access scanning usually happens when PC users try accessing a file or program. It's a real-time scanning option, widely employed today by antiviruses, which ensures malware is detected real-time. Then there's the heuristics scanning option which looks for unusual behavior and blocks them.
Antivirus software(s) usually keep a list of virus definitions aka signature definitions – the pattern associated with a specific virus or malware – and keep updating them regularly in order become aware against the latest malware signature which surfaces from the malware community.
So every time a computer is up against a malware, the antivirus package refers to these list of antivirus signatures and takes the appropriate action.
