- Windows Security
Microsoft’s built-in security solution, formerly Windows Defender and now Windows Security, has evolved to match its competitors in third-party testing results, offering commendable protection for Windows 10 and 11 users.

However, for users seeking basic yet effective antivirus protection without additional costs, the aforementioned free suites offer comprehensive security solutions tailored to varying preferences and needs.
FAQ
-
Will antivirus software slow down my computer?
Antivirus software might affect computer speed marginally, depending on the frequency of scans and system specifications. Other factors like background programs and insufficient RAM can influence computer performance more significantly than antivirus scans. -
What should I do if my antivirus detects a threat?
In the event of a detected threat, antivirus software typically quarantines and cleans infected files. Users can choose to remove or delete infected files, ensuring the threat is contained to prevent further spread. - What is the difference between a full scan and a quick scan?
A full scan comprehensively checks the entire system, including memory, startup programs, and backup drives, while a quick scan focuses on key areas like memory and boot sectors. Full scans are recommended weekly, ideally during inactive periods, while quick scans are suitable for periodic checks prompted by suspicious activity.
