Recommended next steps

Keep your operating system, browser, and security tools updated. Review alerts carefully and do not disable protection just to make an unfamiliar download run.

Frequently asked questions

Should I use two antivirus products at once?

Usually, one active real-time antivirus product is the better choice. Multiple products can conflict or affect performance. A separate on-demand scanner may be used when compatible.

Where should I download security software?

Use the official publisher website or a trusted app store. Check the publisher name and avoid unfamiliar download buttons.
