Hi. Today I downloaded Mackeeper thinking that it was a legit software. I ran a scan, and clicked 'fix' or whatever it comes up with. I then realised the program was dodgy, so uninstalled it following the instructions on their website. I am just wondering whether this program would have done any harm to my computer, and if so would there be a way to reverse it? Also, is there a way for me to make sure it is completely removed from my computer?... I have also been using another program called 'macbooster' and AVG antivirus.. and am wondering whether this is a good idea. It seems like they are good programs, however it is hard to tell. Is anybody able to shed some light? Thanks
