The most annoying bloatware I found on a laptop is HP Analytics. Its only purpose is to get data from you and sell it. It works in the background and you only notice it because the laptop is slow for unknown reasons. To “delete it”, you must disable its service. If you want, you can change its folders permissions so you can delete them as admin. But it will install itself again in a few weeks and you will have to remove it once more, unless you never update Windows and drivers. HP Analytics works like a malware, but antivirus won’t detect it. And you can find this on every HP modern laptop, so it’s very common.


I think it all depends on your PC usage and if you have money to pay for an AV.
I learned all of this using Windows, and you can adapt it to any OS. All of my recommendations are meant exclusively for security, keep in mind that some of them are not the best for privacy.
But the only way to get full and annoying real time protection with all the typical antivirus tools on Linux, is paying an AV subscription. Most AV suites for Linux are developed for servers, I’m not sure if an active plan for home users exists. Just remember, it all depends on your PC usage.
