Review unfamiliar applications and use trusted Windows tools to remove unwanted software.
If you notice unexpected pop-ups, browser changes, or unfamiliar apps, review installed programs and browser extensions. Check an application’s publisher and purpose before removing it. Run a security scan with a trusted tool.
Before you begin
- Save your work and close unnecessary applications.
- Use built-in settings or the software publisher’s official support resources.
- Avoid downloads from pop-ups, unsolicited messages, or unfamiliar file-sharing sites.
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.
