LesGubmit – a good fit for you might be solveiq. Full disclosure, they are a sponsor but offer many of the same type features IObit has in their software. The key difference is the support, you can call/chat them and they will help with your problems, be it a printer, computer setting etc… They also have other features to help speed up and secure your computer. As far as AV goes Windows Defender is good and keeps getting better. Let us know if we can help with anything else!
