Hello sabrejim,
This thread is over two months old. All of the people involved have long since moved on. I only found it because ~Bee mentioned "EtreCheck".
However, I probably should correct some misinformation. It is important to differentiate true malware like the recent Transmission-hack ransomware (see http://arstechnica.com/security/2016/03/first-mac-targeting-ransomware-hits-tran smission-users-researchers-say/) and everyday adware. It is adware that is the subject of this thread. While not technically malware, adware is certainly unwanted and is reaching epidemic proportions these days.
Another contemporary and unfortunate Mac epidemic is scam-ware. There are quite a few scam-ware anti-malware programs around. But an interesting fact is that scam-ware usually is not free. Scamware only exists to scam people out of money. So if you see software that is free, or uses different methods to generate revenue, it is probably not scamware. Almost all of the popular, but legitimate, anti-malware tools, such as MalwareBytes for Mac, is free for end users and requires a paid license only for commercial use. That is how they make their money.
Adware often uses a free "bait" program, but I don't know of any bait software that takes the form of anti-malware programs. Usually they are video players, downloaders, or, alas, Oracle Java. If you are savvy, sometimes you can go deep into the advanced options on the bait's installer or preferences, turn off the adware, and then use the bait software for free.
There is little relationship between scamware and adware. Scamware is successful because they blanket the internet with ads. Since adware is a big ad delivery platform, and scamware vendors are savvy advertisers, they will use adware to market their products. But that is really the only relationship. With scamware, the end user is being ripped off. With adware, some company is ripping off some other company by putting ads in front of end-users.
