That one is medium-security I suggest you use the Kaspersky total which is the premium one. It has a 30 days trial but before you scan the whole PC make sure to update the database first so that it has all possible threats. It will also disable any autorun unknown program
and add a new plugin extension in your browser to protect your browser from any attack. I'm using it for almost 11 years never had any issue except on auto-delete and blocked infected files you can't easily revert it if it was deleted/blocked automatically if it detects any possible threats in your system.

To make sure no malware/keylogger in your system also scans it with malwarebytes combination of these two is powerful.
