Anyway, we got a tip-off as to Elex do Brasil Participações Ltda Technology Inc. being an affiliate company to Malwarebytes, since they suggest an affiliation in their terms of use policy. The reality is while they might claim YAC can do all the things mentioned above, how the product actually performs is an open question. It seems to have the ability to protect users from malicious web sites, cleanup junk files on their system, uninstall applications and even to block advertisements! The Bad YAC itself is a fairly sleek-looking program and very quick as well. They are located in Brazil and have a wide array of products including a speed test, alarm clock, IP lookup and of course, YAC. “Yet Another Cleaner” is owned by Elex do Brasil Participações Ltda Technology Inc. We looked deeper into their operation and found some pretty amazing and ugly things. Recently, we discovered that a relatively popular “anti-malware” product known as “Yet Another Cleaner” or YAC for short, has been claiming to be an affiliate of Malwarebytes in addition to using a lot of our detection names as their own.
