Windows Security

I’ve looked this up a lot, and I keep getting completely different results in each page I clicked.

I want to know what is the best, most secure antivirus, that’s universal (Supports Windows, MacOS, Linux, Android), that detects 100% of malware.

It doesn't need to support Linux, but I thought it would be nice.

If you think "antivirus that detects 100% of malware" doesn't exist, then the one that finds the most malware the fastest

Yes, it can be anti-malware too, but it should fit the conditions above as well.

(Disclaimer: This question and similar questions were Googled before asking here, and I did not find the answers I was looking for.)

Ok, so I'm wondering... what is the best way to encrypt a partition?

I know that Bitlocker exists, but I am unsure if that is the most secure encryption method for a partition. I want the one that is the most secure.

The method should work with [Windows, Linux], this way I can view the backups on any computer I'm using.

I'm wondering in terms of most secure encryption for a drive partition.

Are encrypted drives on Linux more secure than encrypted drives on Windows (in the sense of getting inside)?

I've just been wondering this for some time.

Hello all, I am wondering, what is the most secure method of encrypting partitions on Windows?

I know about Bitlocker, but I am wondering if there are more secure encryption methods on Windows. That is all.

It's not that specific either, so... as long as your answer fits the question, it's good.
