Scanning the computer for viruses and vulnerabilities is one of the most important tasks in ensuring the computer's security. The virus scan detects the spreading of malicious code, which has not been detected by the malware protection for some reasons. Vulnerability scan detects software vulnerabilities that can be used by intruders to spread malicious objects and obtain access to personal information.
Kaspersky Lab's specialists distinguish the virus scan tasks:
- Full Scan. A thorough scan of the entire system. The following objects are scanned by default: system memory, programs loaded on startup, system backup, email databases, hard drives, removable storage media and network drives.
- Critical areas scan. Virus scan of operating system startup objects.
- System's and applications' vulnerability scan. Vulnerability scan is a special tool which helps to search and eliminate security vulnerabilities of applications, installed on your computer, and in operating system settings.
- Custom Scan allows scanning any object on your computer.
