Apologies for the late reply. I had internet problems.

Is there any possible way to know if this new machine will have it? How i can check it before buying it? And let's just said that i bought it, where i can see or with what way i can search test my machine to see if this thing is installed?
There's only one way to make sure if a Lenovo laptop has Superfish before buying it. Look up the model and see when it was officially released by Lenovo. If it's
not between October 2014 and June 2015 (December 2015, for example), it should be safe. Otherwise, you need to actually have the laptop first with Windows installed. Go to C:\Windows\System32 and see if there's any file named LenovoUpdate.exe or LenovoCheck.exe. If you find them, that means the laptop has Superfish.
If you have advanced networking knowledge (or are willing to try things out), you can use tools like
Wireshark to monitor and analyse your network connections for anything suspicious. You can also use a tool called Resource Monitor that already comes with Windows by opening start menu, typing
perfmon /res in the search bar, then pressing enter. Resource Monitor has a network monitoring tab that you can use to see if anything tries to connect to Lenovo's servers.
If i will buy this Lenovo, can i do a clean install of Windows 7; I kind don't like the Windows 10 and i hate even more the Windows 8-8.1
Provided you know how to install Windows from scratch, yes, you should be able to. Make sure to do an actual clean install: boot into BIOS, wipe out the entire hard drive partition, repartition it as you need, then install your Windows of choice. If you can get an empty laptop (with no OS whatsoever installed; they're usually kind of grey area items) that's even better as you can save some money.
My price range was restricted to 500 euros total. But if there is a chance to buy a good machine with a bit higher price like those 2 i can do something and buy them.
But i want you both from your hearts are those two machine worth those extra money? Or i should stick with Shishou's Lenovo suggestion?
I personally think the Lenovo laptops DA linked earlier are better. As DA mentioned in his post, the graphics cards in those HP and ASUS laptops you linked use shared memory, and as far as I know, AMD Radeon R5/R6 is integrated graphics instead of a dedicated GPU. That's probably what makes the prices relatively cheap, but on the other hand, the HP laptop has a 256GB SSD and the AMD one has a 512GB one.
In other words, the cost distribution is stupid. You get a large SSD, which jacks up the price considerably, but
not a dedicated GPU and only integrated graphics, which makes the price lower. This means that the bulk of what you'll pay goes to the SSD. Since you have a limited budget, if you want an SSD but you don't game, 128GB should be enough to put programmes you use everyday. The rest of the money can be allocated for a laptop with a dedicated GPU.
Oh, lastly, avoid buying computers with "up to" claims, especially with regards to CPUs. They can be misleading by referring to "burst" (short periods in which a CPU executes instructions) or even overclocking. If a seller says the speed of a CPU they're selling is "2 GHz up to 3 GHz", that likely means you won't get close to 3 GHz most of the time.

It's interesting but i don't believe the most tests from many sites. My real life experience seems a bit different but i can't also deny the tests. In my experience many times while working with a specific laptop i see a small difference of only 10 - 15 not big deal compare to the mechanical drive that it used to have, but even so those 10 - 15 minutes minutes where crucial.
Fair enough, but the methods are explained. Your experience is valid, of course, but also anecdotal and may differ from others. That's the thing about benchmarking: you try to get results are as accurate as possible by making sure that every test is done in an identical environment and conditions. If computer A with a 7200 RPM HDD is used for browsing the internet, and computer B with an SSD is used for gaming, the SSD in computer B may be hotter.
Is this because SSDs are inherently easier to get hot than conventional HDDs? Maybe yes, maybe no. It could mean that, or it could mean that in computer B, gaming heats up the CPU and GPU, making the motherboard hotter and by extension the SSD. In other words, anecdotal measurements are likely inaccurate. (That's the short version of it, anyway. But your post provides a range of nice citations. :))
@Ignis; I don't know if i am wrong but for safety reasons isn't there any possible way to upgrade the bios of this Laptop with a hacked version that it's clean from superfish and it doesn't allowed the system to connect at lenovo's servers?
But there is also and a chance that this laptop is definitely a newer model 2016, so it might also not to have anything "weird" installed at it's bios...?
Yes, but it's by no means simple. Unless you can afford the time, skill and risk, it's much better to just avoid Lenovo altogether if you're worried about Superfish. Check out
Libreboot. I'll admit that I've never used it myself, though, so I can't help much with that.
But yes, as I mentioned, according to Lenovo itself, Superfish only existed on laptops released between October 2014 and June 2015. Newer laptops are hopefully safe.
