welcome to MT there are a few vendors out there that seem to be consistant in getting high scores from testing labs , like kaspersky , emsisoft , gdata , bitdefender eset. or free avast , AVG , qihoo 360. but their is no product that can provide 100% detection. the weakest link in the chain is the end user , if the user screws up by visting crack and ware sites or surf porn or other shady sites you will enventually end up infected , no matter what product you use! just use the product you are most comfortable with and most importantely you brain , intuition and heart!
