Because I was on a different computer than lowbrow users problems when installing a program, I got myself to install this software equally savvy help. After the old-virus program was uninstalled from an older laptop with Windows 8.1, this protection program could bring no problems and running, the installation worked flawlessly. When scanning, the software will take longer for it is but apparently very thorough, several threats were found. Overall, the scan took just over an hour, but can certainly be due to the cluttered PC. The user interface was clear for me to understand and easy to operate, and I had questions but with expert help at my side. Those who know a bit, should have no problems with this software. The computer has not slowed down in the performance of the protection program that runs in the background, the user gets little with. I now feel relatively well protected and have the feeling that they have done nothing wrong in this program.
