Hi! Thanks to help those who really need to learn the bases of computer protection! My mom is using the computer to seek for houses to sell with a professional programs, could avast think that we use it to make money and stamp us as a company? How do they look if we use our compu. for lucratives activities? Can someone tell me what's the difference between avast and AVG ? is it really better ?... why does avast ask me to register ? will they send a lot of annoying e-mails?
