on a phone, it's impossible to tell which folder it is in, but on a windows computer, they usually install some software onto either System32, or SysWOW64, to monitor it. delete those two folders, and you should be safe. And just to be extra careful, don't use any proprietary antivirus or firewall, they carry monitoring software too. And, final tip, Internet explorer is probably your safest browser option. either that or google chrome. They don't get monitored, or exploited. Very safe!
