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.
