There is no such thing as the "best antivirus". It is all based upon your personal preference. Also, since new viruses are coming out every day, antivirus companies are struggling to stay one step ahead of malware authors. No one antivirus program is going to detect every virus, partly due to human error in analyzing the virus and software bugs.
If you need an antivirus program and don't want to spend money, I recommend downloading MalwareBytes, which is a free anti-malware program and it is VERY effective.
