In recent years, computer viruses have been multiplying, increasing the risks for unprotected users. Not having an antivirus can have serious consequences, including data theft, resale or even complete destruction.

Windows has a built-in antivirus program that protects you superbly against malware, is completely free and is constantly updated to protect your computer.
