There are free security suite applications available. They are really free to download. However, installing free antivirus programs has its disadvantages. Not all free antivirus products are updated. Thus, most of the time, free antivirus software cannot recognize, detect, and identify new viruses and malware. The databases are not updated in some of the free versions of antivirus products.

Aside from free versions of antivirus and security applications, there is also the trial version of antivirus products. Trial versions are made so that users can evaluate the products. Trial versions of antivirus products are more updated than free versions of antivirus software. However, trial versions of antivirus software usually last for 30 days only. Thus, you need to download another antivirus product or purchase the licensed version of that malware protection software.

On the other hand, licensed versions of malware prevention programs are considered the most effective of the three versions. Although they are effective, they come with a price. There are people, though, who cannot purchase the licensed version so they stick with the free and trial versions. Licensed versions entail more complete protection and are easy to update. They have more benefits than the other two versions like updated databases and strict security. Moreover, licensed versions have more tools for protecting your computer than free versions and trial versions have.
