There is software that allows you to brute-force this kind of manipulation. I've never tried it, for fear of a virus, but even if they are surely "safe", is it possible that a software finds my seed?

It depends on how much you remember from your seed. If only few words are missing (like 3 or 4 words) and you know their exact position, then recovering the seed using a good tool is possible. The more you remember the faster the tool will find your seed. Once it finds it, you can use it to recover your wallet and you will have full access to your coins.

I've seen many reputable members recommending BTCRecover, so I believe it's safe.

Most seed phrases have an entropy of (I'm not sure how many words are used for the checksum so just found the entropy of the first 10 words): 1,298,074,214,633,706,907,132,624,082,305,024 (2048¹⁰)

Given the method used by electrum for generating a seed phrase, even the last word contains 11 bits of entropy.
So, a 12 word seed phrase generated by electrum provides entropy of 2048¹².

This isn't as big as the keysize for private keys (unless you use a 256bit seed or you made your wallet a few years ago - it made different length seeds) but it's still very huge and uncrackable.

I use Electrum since many years ago, and I've always wondered how the seed is managed.

Your seed phrase actually represents a random number.

I explain, if for example I test several words in order, Can-I find the seed of my wallet?

That's impossible.

If I find it, I have access to all the funds right?

Yes, the seed phrase is all you need to access the fund.

You can brute-force the seed phrase only if you know some words. For example, if you know 10 words, you can test all combinations and find the 2 missing words.
It's not that you can brute-force any seed phrase. A 12 word seed phrase generated by electrum provides 132 bits of entropy and it's secure enough.
