Uhm no? Windows Defender is by no means Spyware... By that logic Windows is spyware, might as well use Linux at that point. Honestly, never heard Webroot being formidable in any field of Cyber Security, I would go with ESET. If you are looking into different anti-virus solutions, I would recommend investigating popular alternatives as they are far better than your current options right now. And honestly, in regards to WD(Windows Defender), it works well. Because no matter what you do, no software will protect you 100% and if you are an aware user, there won't be any issues with it.
