Frequently Asked Questions

Does a home computer really need an additional third-party antivirus?

For the vast majority of users, the built-in Microsoft Defender on Windows 10 and 11 provides excellent and sufficient protection, provided it is kept updated and active. Third-party options can offer extra features, but the built-in tools are highly robust.

How often should I back up my home computer files?

It is best practice to automate your backups so they occur continuously or daily via a secure cloud service. Additionally, keeping a weekly offline backup on an external hard drive provides extra protection against advanced ransomware.

Why should I use a standard account instead of an administrator account for daily use?

Running a standard account prevents unapproved software, including malware and viruses, from making system-wide changes without your explicit permission. This significantly reduces the damage if you accidentally click a malicious link.

How can I easily tell if an email link or attachment is a security risk?

Always verify the sender's actual email address (not just the display name), avoid opening unsolicited attachments, hover over hyperlinks to inspect the destination URL before clicking, and trust your email provider's built-in spam filtering warnings.
