Even if you wanted to, it is still difficult to use Windows without an antivirus program. The system constantly warns you when such a guard is not active. However, a lot of security software lets everything through because it simply doesn’t fit into the categories being scanned. A typical example are cookies that register your surfing behaviour. In the distant past (2014) we already wrote about SuperAntiSpyware here, a program that detects these kinds of things and has only become more powerful since then. You simply use it alongside your existing antivirus.
