Free antivirus software is readily available on the internet. Basically, companies who create this antivirus software give a free basic version available for public usage. This is actually to convince consumers to buy the full version so that their computer could be fully protected.
This free antivirus review will discuss upon some specifications to determine whether the software really detects threats or simply false positive. The first test the free software has to undergo is the detection of zoo virus. Basically, the products have to detect some 'control viruses and the higher the number of detections, the better is the antivirus software.
The antivirus software should also be able to detect new virus that appear on the internet. Therefore, the vendor that releases the information of the newest virus the earliest is the most reliable. However, some virus creators deliberately trick the signature-based scanners by repackaging a known virus using a different compression or archive type. So, the antivirus software has to be able to decompress the file to scan it for virus.
Usually, free antivirus software fares badly in the adware and spyware category. This is because this specification is not available in the free version; instead you would have to buy the full version to enjoy this service. The software is also tested on the footprint they leave behind because this is a gauge on how much memory the full version will take. On average, they take up 40MB of the disk space which is quite little.
As a conclusion on this free antivirus review, the software is tested on how well it could remove a stubborn infector. This is because some of the free solution could not remove it because this service only comes in the full version. To remove it manually, one has to go to the vendor's database to look for the infector and remove it by themselves.
