New Build needs AntiVirus & Cleaner
 

I am putting together a machine for engineering and business management.
SolidWorks and QuickBooks + MS Office etc. and connected to the Internet.

What AntiVirus should I go with?

What Cleaner software is good?

Thanks in advance!

Get it behind a hardware Firewall/NAT router first.

Basic software: Windows Firewall enabled, Avast, MalwareBytes, CCleaner

Router is essentially mandatory these days.

Microsoft Security Essentials (free) for basic protection, plus Malwarebytes (free edition) for doing manual scans. CCleaner (free) for maintenance.
