Ok 12 antivirus programs is definitely over the top and in the majority they will be working against each other rather than making you safer. It is far better to chose one reliable program and stick with it.
Once you are using the one you like do not be complacent and assume because you have a program running you are safe, or in Glen's case assume because IOS does rarely gets viruses you are safe, it only needs one to penetrate the system!! Keep aware of how your phone/computer/tablet is performing if it slows down or starts acting oddly check it out, do regular scans, keep it backed up so you can recover the system if necessary. Don't believe the hype out there that IOS cannot get viruses as Del stated it has happened, and as Apple gets more users and makes more money there will be more incentives for those people that like to make your life h*&l out there to write the code to attack IOS
You should also remember that Viruses are not the only problems out there, your phone/tablet/computer can be hacked to obtain passwords personal information and banking details, this is probably far worst than having a virus. IOS is just as vulnerable as any of the other operating systems to this.
So in short stay aware, ensure you have secure passwords (no using PASSWORD or 123456 or 98764, or your birthday etc are not secure options for passwords)
Love is better than anger. Hope is better than fear. Optimism is better than despair. So let us be loving, hopeful, and optimistic. And we will change the world. - Jack Layton (1950-2011)
