Hello, over a month ago this Max Security sofware and Microsoft Defender were turned off. I don't know the reason why. I can manually turn on Defender but it goes back to being off. Could my laptop be infected with a virus that turns off anti-virus software?
Thank you for posting your concern here and welcome to the community!
Based on your concern, you want to know why your Maximum Security and your Windows Defender was turned off, and if your computer is infected by a virus that turns off anti-virus software, right? Please allow me to help you with this.
Your Windows Defender and your Trend Micro Maximum Security can't run on your computer at the same time. Your Windows defender will automatically be switched off when you install your Maximum Security. You may open the main console of your Maximum Security program to check if your computer is protected.
You can also do a full scan if you want to verify if there is any threats on the computer. In case that your Trend Micro is not working properly, you may use our HouseCall to scan your computer for malware. Please refer to the link below on how you can use this tool.
