It helps us to help you with suggestions if you provide more details, such as what you have for real time security, on demands and privacy, what you use to block ads, trackers, ect.
First of all you must have a backup and recovery plan: Windows default or third party apps like Paragon B&R or Aomei (both free).
The protection offered by Windows Defender is sufficient for normal use.
In addition you should at least use Malwarebytes and Emsisoft Emergency Kit as on demand scanners.
Alternatives: Avast (free), Bitdefender, Kasperky, Norton (paid) that may have an impact on your system performance.
Please refrain from using all caps
Consider some on demand scanners
Consider using just CCleaner or Privazer in place of AVG Tune Up
Consider some type of back up solution
Consider using a Password manger
Consider using uBlock origin in place of ABD and HTTPS Everywhere in Chrome & FF
Please reference the following thread to edit your config [MUST READ] How to update your security config without creating a new thread!
As much as possible if you are going to test phishing site or possible malware samples rest assure to test them on a isolated environment like Virtual Machine or another computer.
Take an extra precaution since Windows Defender holds the protection within baseline, so with enough common sense and guide through awareness then it shouldn't easily infected again.
Nice little configuration, unless you specifically use this configuration to test malwares you should get a better protection. for instance AVAST has a free version. Or add to Windows defender malwarebyteantimalware pro, or superanispyware pro for their realtime protection.
@ABHINAV RAO: Rest assure that Kaspersky daily updates on their beta stages that will apply on the stable version should lessen the problems on Windows 10 although you can use it on primetime as their effectiveness is brought already to be matured enough.
