MajikTom Posted October 28, 2020 ID:1416992 Share Posted October 28, 2020 This is getting very concerning. I can't open any MS Office files for the last week. Please roll out a fix as soon as possible. Link to post Share on other sites More sharing options...
exile360 Posted October 28, 2020 ID:1416993 Share Posted October 28, 2020 A new build has just been released, so if you have not installed it already, please open Malwarebytes and check for updates and install it, then restart the system once it finishes and see if the issue has been resolved or not. If it still persists, open Malwarebytes and navigate to settings by clicking the small gear icon in the upper right, then select the Security sub-tab and scroll down to the Exploit Protection section and make sure the option to block penetration testing attacks is set to Off (it should be by default, however it's a known issue that some defaults are not configured properly on some installations), then click the Advanced settings button and click on the Restore Defaults button at the bottom of the advanced settings window. Once that's done, wait approximately 30 seconds to allow the protection to refresh itself, then test to see if the issue still occurs or not. Please let us know how it goes.

Staff Arthi Posted November 2, 2020 Staff ID:1418030 Share Posted November 2, 2020 (edited) Hi MajikTom, Can you please post this file here C:\ProgramData\Malwarebytes\MBAMService\logs\mbae-default.log There were multiple Exploit protection related issues - some of it resolved with restore default settings and turning off Penetration testing protection, some of them were fixed in the last product update released, some of them we are still taking a look into. So I would really like to check this log so I can offer a workaround/resolution accordingly. Thank you. Edited November 2, 2020 by Arthi Link to post Share on other sites More sharing options...
NovaRays Posted November 7, 2020 ID:1419113 Share Posted November 7, 2020 Hello all, I'm not a tech guy but I did have the same issue. I noticed that it only affected Microsoft documents I had stored in my OneDrive. I sent a copy from OneDrive to my coworker and after downloading it to my desktop, it opened without any issue. For me anyway, it seems to be that Windows OneDrive was causing the problem. Alternatively after testing, I found I could also right click on the file in OneDrive and choose the 'Send to' option and send it to another drive or a USB and it also opens without issue. Hope this can help someone. Link to post Share on other sites More sharing options...

NovaRays Posted November 7, 2020 ID:1419115 Share Posted November 7, 2020 Yes, I have the most current version 4.2.3.96 - Update package version 1.0.32552, component package version 1.0.1104 I am looking into the OneDrive issue as this problem only seems to affect office documents in my OneDrive. If I learn more I will share. Link to post Share on other sites More sharing options...
exile360 Posted November 7, 2020 ID:1419117 Share Posted November 7, 2020 If you haven't done so already, please try opening Malwarebytes, navigating to settings by clicking the small gear icon in the upper right, then selecting the Security tab and ensuring that the option for blocking penetration testing attacks is disabled, then click the Advanced settings button and click on the Restore Defaults button at the bottom. Once that's done, wait around 30 seconds to allow the protection to refresh and settle down (or just restart the system) and test to see if the issue is now corrected or not.

NovaRays Posted November 7, 2020 ID:1419124 Share Posted November 7, 2020 Thank you exile360. That seems to resolve the issue with OneDrive. However, now my concern would be not having protection against penetrating testing attacks. For now, I think the work-around of not opening directly in OneDrive will be OK. Hopefully since the issue is known it will get resolved without the need to disable the feature. Link to post Share on other sites More sharing options...

exile360 Posted November 7, 2020 ID:1419126 Share Posted November 7, 2020 To allay your fears a bit, penetration testing attacks are just what they sound like; they're just tests performed by professionals that are hired by companies to test their security measures, not defenses against actual in-the-wild malware/hackers, so you really aren't losing any protection from anything you'd ever encounter in the real world.
