FAQs

Q: How often should I run a Windows malicious software removal tool?

You should run a full system scan at least once per week. Run quick scans daily if possible. Use on-demand scanning whenever you download files from the internet or receive email attachments. If your computer starts running slowly or acting strangely, run an immediate scan. Regular scanning helps catch threats before they cause serious damage to your system.

Q: Can I use multiple Windows malicious software removal tools together?

Yes, you can use multiple tools, but be careful with real-time protection features. Having two real-time scanners running simultaneously can slow down your computer and cause conflicts. Use one tool for real-time protection and others for periodic scanning. Many users combine Windows Defender with tools like Malwarebytes for comprehensive protection without system conflicts.

Q: What should I do if my Windows malicious software removal tool finds threats?

First, let the tool quarantine or remove the detected threats automatically. Restart your computer after the cleaning process completes. Run another scan to make sure all threats are gone. If the same threats keep appearing, try a different removal tool or boot from a rescue disk. Change all your passwords after successful malware removal to protect your online accounts.
