I disagree with @Mitchelllucas,
Im working as an independent Malware Researcher and Reverse Engineer. I see the dark site of the web everyday and trust me, until nobody finds a "perfect" solution no cyber-criminal will stop trying to get your money.
There is no "best" antivirus solution out there. The "best" way to stay safe in the web for a normal consumer is not to trust anyone as yourself.
I personally don't use av stuff. Only an anti-executable and deep freeze on my home computers. But I absolutely recommend an av solution for non-professional IT users.
I would suggest you one of the av's with highest detection in combination with an alternative scanner like Malwarebytes Anti-Malware. To prevent Exploits like java-driveby's, flash or browser attacks for example take a look at Malwarebytes Anti-Exploit.
Here are some interesting sites for different perspectives of detection

False positive rates are a major issue with trainers due to the way they function in that they:
1. Activate on keypresses
2. Modify the game exe file while in memory
Both actions are enough to trigger many false positives.
