Good is a subjective term; nevertheless, some free antivirus programs (depending on the user's wants and needs) include, but are not limited to: AVG (considered by some to be the best), Avast!, ClamWin, Comodo, Panda Cloud, and digital-defender.
I would recommend Avast or AVG. They are both good programs (with free, lite versions).
Some free antivirus programs include: NOD32 and Kaspersky. The cheapest antivirus programs are the free ones but the protection may not be as great as the paid versions. Some free antivirus programs include: Avast Free, AVG Free, Avira, Bitdefender, Comodo, Immunet, Kingsoft, Microsoft Security Essentials and Panda Cloud Antivirus.
There are many sites that allow someone to download an antivirus application for their mobile phone. Sites like kaspersky, avast, nairaland and antivirus are all sites that offer free antivirus downloads.
Choosing an online antivirus can be difficult at times because there are so many out there offered. Some of the best free online anti virus programs include; AVG, Microsoft Security, Comodo, McAfee and Avast.
Some programs aimed to increase perfomance of computers are not compatible with antivirus software.
It depends if the program comes from a reliable vendor if they do then NO however free AV programs are not a refined as paid programs so they may produce false positives more often. But a some free anti-virus programs are actually a virus/trojan and they will fake viruses and try to get you to pay to remove them. and steal your credit card number if you want some free good reliable anti-virus programs i would recommend: Avira, Avast, Trendmicro, IObit, AVG, and Malwarebytes

According to consumer reviews, Microsoft's free antivirus software performs better than some paid antivirus programs in studies. In one such report by ZDnet, Microsoft's antivirus software detected malicious scripts that other software programs did not. In addition, most users have reported the software to be convenient due to its auto-pilot features and ability to run unnoticed without using too much of the computer's resources.
