Free antivirus software can be an excellent choice for those who only require basic protection. However they do not provide the same level protection that paid-for solutions. The best free AV software will often offer the highest levels of malware detection and are endorsed by independent labs like AV-TEST or AV Comparatives, but they won’t come with the added extras that are typically found in premium products. These extras, which include threat protection for networks user profiles, VPN, password managers and parental controls are crucial to full online security.
The free antivirus programs aren’t regularly updated like paid-for solutions. This leaves a gap for spick and span malicious software to escape detection. The majority of free antivirus software rely on signature detection which consists of checking malware samples against strings of characters associated with known attacks. This method is successful when attackers utilize the same patterns. However sophisticated hackers are using techniques which are unique enough to defy detection.
You should also take into consideration the terms of use of a particular antivirus software. The majority of free programs are licensed for personal use and may not be suitable to business users. Furthermore, some free software may include software that could be classified as spyware or adware which is why they should be downloaded with care. Paid solutions are more likely to include warranties and guarantees that outline what the user can expect in the case of an attack.
