They all delete and block and show no way to restore, and make it extremely antagonistic for users to keep keygen type files usable or they hide them so they don't even show up in some antivirus quarantine lists! They must be getting some deal from the RIAA or some other sacks of what is found below outhouses in the software corporate world to do this, thinking that the base of people this would bother will just be a small percentage of their sales targets.
WRONG....
Why not just buy the software for big bucks? Because when you discover the software doesn't perform as advertised, you wouldn't have bought it anyways, but would have lost the money you spent for it.
When I find software that actually works, and doesn't bluescreen or crash and It is something I really want or need for the value it delivers, I'll then gladly buy it. These companies that can't understand this anyway because they have 250,000 dollar a year marketing execs who can't even peel a potato making these retarded decisions, but find they can make more money for the company by writing off the falsely acquired projected losses from so called infringers on their yearly taxes!
This is the true reason for anti virus programs all doing the same thing and making their programs difficult to "reacquire" the files it gets rid of or hides all the ways to restore them, and, or, makes you go through lots of menus to find the file it took from most forms of system visibility, think most people won't care anyway. WRONG
