I have a macbook pro and have downloaded a free version of mackeeper. (I know. You get what you pay for usually. I'm really poor. I will be buying antivirus software as soon as I can afford it.)
This is probably a stupid question, but I don't know much about computers beyond the basics.
When a free antivirus program (in this case, mackeeper) says the system is critical, does that mean my computer is in danger of crashing any minute and I should buy the better version even though I can't really afford to at the moment? Or is it an exaggeration to encourage me to buy the better version?
