The real-time protection module uses our advanced heuristic scanning technology which monitors your system to keep it safe and secure.In addition, we have implemented a threats center which will allow you to keep up to date with the latest malware threats.Malwarebytes Anti-Malware is considered to be the next step in the detection and removal of malware.In our product we have compiled a number of new technologies that are designed to quickly detect, destroy, and prevent malware.The Malwarebytes' Anti-Malware Database allows you to always keep your copy of Malwarebytes' Anti-Malware up-to-date even if you don't have an internet connection available on the computer where the program is installed.Note: You can download the Mbam Setup which is an executable (.exe) which updates the file automatically or you can download the updated and just place in the directory C:\Program Data\Malwarebytes\Malwarebytes' Anti-Malware\ replacing the existing file.You mention that you are running MBAM Free; however, if any of the affected systems runs MBAM Premium, please be sure to deactivate your license before uninstalling (as explained in the sticky topic for which @qm7 provided the link).
SECOND STEP It is possible that the program has been compromised by some high-tech stealthy malware that prevents Malware Bytes from operating correctly.The behavior you describe sounds more like a possible software conflict (AV or firewall), networking issue (perhaps a proxy?I didn't say that the update fails (sorry if my english is bad). I've found a similar topic there: https://forums.malwarebytes.org/topic/174321-blue-update-bar-always-stalls-when-finished-updating/ (Ironically, installing 220.127.116.114 seems to have solved the topic starter's problem.) No malware, no firewall, no problem with time/date I just wanted to know if there are some people with that behaviour.So, if you upgrade to the current version, the problem should be resolved with updating "hanging" when a new program version is available but automatic program update checks are disabled, as explained in the 18.104.22.1683 changelog HERE.Millions of users update MBAM Consumer to the current program and database versions without incident.
For this reason they have developed a free tool called “Anti-Rootkit” that targets malware programs that are trying to block Malware Bytes.
