I am going to recommend you remove that Antivirus and use the built in one instead.
Windows Defender has come a long way from the days of Microsoft Security Essentials.
It includes a decent Antivirus scanner thats more robust and uses heuristics and the cloud to detect and remove malicious code.
There is also a built in offline scanner you can use to scan Windows outside of the installation.
Windows Defender also includes a Firewall, Network Security and protections again newer types of attacks such as Ransomware.
So, its pretty robust, especially when combined with other security features such as Windows Smart Screen Filter. I think when used with a Standard User Account, some common sense - don't just download software from suspicious websites or open strange emails with attachments.
Also, keep a regular backup of your computer, system restore points; you really can't go wrong.
You can also supplement it with third party solutions such as the ESET Sysrescue offline scanner and Malwarebytes.
