If you follow these chapters once a month you will keep your machine running at top performance. You could also purchase the software that will help keep your protection solid but that depends on your budget. There are too many products on the market these days that can help keep your machine in top gear. As I mentioned before, I am not a big personal anti-virus user (unless in a company environment) as it has been years since I have had a virus. My problems have been exploits with malware and browsers. I know anti-virus products are into the malware protection these days, but these tools listed here have had many years of development ahead of companies like Norton. I have tried them, but they are with Windows Defender as "Software getting better but not quite there yet" category.
