1 - Most of these methods are avaliable online, mainly on torrents for FREE.
2- There is no such thing as LIFE-TIME.
3- MOST methods contain malware/viruses or/and phishing activities.
For an example getting a working method to activate and update Kaspersky for an instance. there only 2 reasons why would it work.
A- The devs know about it and they are allowing it for some "Not so great" reasons !
B- it is really a loophole found by somebody that does work but will soon be busted !
Unless you are too naive, you do not think that these multi billion companies with the best and most experienced IT people working for them are too stupid to allow pirated copies of their software to be used !.
be careful on what you try to save on ! there are things in life that you just need to PAY for. do not be stingy ! buy the freaking software.
