It has some strengths and weaknesses. But I won't upgrading to the paid version. Why not? Well, every day the same nag message comes up:
F-Secure would like to have your phone number for the purposes of possible product information and marketing related messaging. The cost of approval is that of one-stime standard SMS to Finland. Do you agree?There are two buttons.. Yes and No. Click "No" and the message seems to go away.. until the next day. And the day after that. And the day after that. You get the picture. Either this is a bug or it is a very aggressive attempt to get you to agree to SMS marketing. Either way it's a big turnoff and I'll be looking for another product to protect my Android..
