Malwarebytes: "Exploit code executing from Heap memory blocked" - MX5


Recommended Posts

MX v5.3.8.2100
Windows 10 Pro

Hello

Installed Malwarebytes (MBAM) yesterday.

Today, when I open MX5, it is blocked and closed by MBAM around the time the "Last Session" page opens. 

It is necessary to End Task in Task Manager after it is blocked. (Maxthon is consuming "High power".)

The report is pasted below. 

The report appears to be the same one reported on September 5 in the Maxthon Francophone section here https://www.maxthon-fr.com/forum/index.php?/forums/topic/12582-connexion-compte-google-impossible/ (French language).

Hi TheWhippinpost, you could try to add Maxthon to the whitelist. 😊

Thank you. Didn't work unfortunately.

I whitelisted:

maxthon.exe
mxStart.exe
mxAppLoader.exe

And I tried excluding the whole Maxthon folder.

Another tactic I tried was to instruct MX to open four web-pages using the command-line. It began loading the web-pages in turn but again, around the time it opened the Last Session page it was closed by MBAM.

I am having the same problem. The suggestion to uninstall Malwarebytes is crazy. You should not not have to uninstall a security program to run a browser. That should be fixed at the Browser level. What I did was whitelist 43.242.73.253 which appears to be a link that provides the Favicons on the Start page. Maxthon should contact Malwarebytes to let them know that the site is safe so they remove it from the blacklisted ones. A lot of people use Malwarebytes and many are likely to uninstall the browser, not Malwarebytes. That program is an essential safety tool.
