While it’s great to be able to protect your computer system for free using one of these free antivirus software, there are also some disadvantages to it.
A free antivirus slows down your computer.
First of all, many free antivirus software slow down your computing system. Since these are trial versions, they are not optimized to work efficiently with your system. Thus, your computer runs slower than usual.
A free antivirus might affect the speed of other applications.
Since your free antivirus is not optimized, when you run it, this can potentially slow down your other running applications. This is a big hassle since you will need your free antivirus to always be running in the background. This results in slower computer performance.
A free antivirus has limited features for filtering and protection.
Your free antivirus software will definitely have limited protection and filtering. Since only full versions offer total computer protection, your system is at a disadvantage. You are still exposing your computer to harmful viruses and malware because of your limited antivirus protection.
