I have over 30 years experience. I have one year contracts with doctors, lawyers, churches, etc. and I get one fee annually. I can’t be running out to remove viruses. I won’t get paid. For Win7 use Microsoft Security Essential and Windows 10 use the built-in Windows Defender and that’s all. Remove all others. Not that Malwarebytes, Trend, Kaspersky are bad products, they aren’t. Just unnecessary and they hog system resources and make your computer slow. Also, get a 2 terabyte, external if you have a laptop, hard drive, buy Acronis True Image 2017 and make a daily backup of your entire hard drive. Problem solved. You’re bullet proof.
Microsoft is only 96% effective on identification of recent malware:
