It is generally recommended to have an antivirus program installed on your computer to help protect against malware and other malicious software. Antivirus software can help detect and remove viruses, trojans, worms, and other types of malware that can harm your computer and steal personal information. It can also help prevent these types of software from being installed on your computer in the first place. However, it is important to note that no antivirus program can provide 100% protection against all types of malware, and it is also important to practice safe browsing habits and keep your operating system and other software up to date to help prevent infections.
