Can you start by doing a check for Windows updates first? We have identified an issue that can prevent drivers from loading, but if you have all the available Windows Updates it should not be an issue

Make sure you're downloading the proper installer for Windows XP, which can be found here: https://downloads.malwarebytes.com/file/mb3_legacy 

You have our servers blocked in your hosts file. Please remove the following two entries from your hosts file and then try to activate again
Host data: 0.0.0.0 serius.mwbsys.com Host data: 0.0.0.0 keystone.mwbsys.com  

The Malwarebytes license server is being blocked in your hosts file, you will need to remove the following entry to allow the product to work properly.
Hosts: 127.0.0.1                   keystone.mwbsys.com  

As answered, any legal queries should be sent to legal@malwarebytes.com. Locking this thread as that's the best answer.

Ok, so this looks to be working as expected. Let's break this down into two issues
Blocked category is different:
If you look at the notification, you'll actually notice that the website being blocked is different. When the category is Malware, the URL being blocked is j.gs. But when the block is for Fraud, the URL being blocked is files.iqoption.com. This happens when the page you're visiting is trying to load different scripts or assets from multiple websites, so this is expected.
Notification not showing up:
This is due to browser caching. When you go to a site, and then that site doesn't load for some reason (IE: the site doesn't exist, or your antivirus blocked the site) your browser will remember this and cache that response. The next time you try to go to the site, your browser looks in the cache first, and if it has a recent copy of that site, it will try to load that. Since the last time you went to the site, it was blocked, Firefox loads the blocked version. When you click the refresh button, you're telling Firefox to skip it's cache and load the site new, which is why the block then shows up properly. This is a feature of browsers, and is unfortunately not something we can easily bypass without forcing your browser to empty it's cache occasionally. 
Let me know if you have any questions.

It looks like you have a broken install of Avast that might be causing some issues. Let's start by using their removal tool and see if that helps the situation at all.

A few people have reported that the information on the map is working as intended, so the issue definitely seems to be with your setup. Without logs though, there's not much we can tell you in terms of why it's not working for your setup. You are welcome to send the logs to me directly if you wish and I can move our conversation to PM to make sure the information isn't released publicly, but at this point, that's our only option.

This block was removed a week ago, please make sure to update your databases to the latest version

That log wasn't ran in safe mode, it was ran in normal mode, but I do see a few things jumping out.
For starters, please right click the desktop icon for Malwarebytes and then choose Properties. Click the Compatibility tab on the top and then uncheck all the boxes on this page and click Ok. Then try to launch Malwarebytes again.
If that doesn't work, please reboot into Safe Mode and try to open Malwarebytes. If it launches, please run a full scan with rootkit scanning enabled on your machine.

This sounds like a different issue. But to rule out Malwarebytes, you can boot into Safe Mode and then uninstall Malwarebytes. Then reboot back to normal mode and see if your computer works properly. If it does, try installing the latest Malwarebytes.

Can you try disabling Windows Fast Startup to see if that makes a difference: https://www.tenforums.com/tutorials/4189-turn-off-fast-startup-windows-10-a.html

That version is not supported on Windows XP. You will want to download this version: https://downloads.malwarebytes.com/file/mb3_legacy. Note that 3.5.1 with component update 1.0.365 is the last supported version on XP, and no updates past that are supported on XP

Thanks for the information everyone. As mentioned, we have been able to reproduce this issue. There doesn't seem to be any negative impact from this issue that we've identified other than the error message in the log, so you should be ok to leave things as normal. If you want to remove the error though, you can disable Self-Protection in the meantime.
We are currently looking at how many people are being impacted to understand if we need to release an emergency hotfix for this issue, or if we will wait for our next scheduled release. Feel free to each out with any questinos.

Nothing jumps out malicious, but I do see that you installed some free video editing software recently. A lot of times these types of software come bundled with additional software, such as the Mcafee Scanner, and install it alongside. This seems like the most logical explanation of where that came from.

This issue is now confirmed fixed by a large percentage of our user base. If you're still having issues, please make sure you on the latest version of Malwarebytes (at the time of this article, it's Malwarebytes 3.5.1.2522 with Component Package Version 1.0.441).

If you continue to have issues after that, please make a new post using the following as a guideline
 

What's happening is that the Kaspersky Rootkit scan is preventing our Web Protection driver from reloading after a database update. This is why the error only happens sometimes (you have to be running a rootkit scan, and a database update for Malwarebytes has to happen at the same time). Unfortunately the only current workaround is to disable the rootkit scanning in Kaspersky.

It looks like you have some exclusions setup for your network drives, which most likely aren't mounted when Malwarebytes starts. We have a fix for this coming soon, but for now, you'll need to remove these exclusions and then restart Malwarebytes.

Thanks for the logs, it looks like your upgrade process didn't complete successfully. You should be able to download the latest version from https://downloads.malwarebytes.com/file/mb3 and install it over top of your current installation.

We do not support scanning network drives. There was a bug earlier when network drives could be selected to scan, but no files were actually scanned on the drive. Now the drives are not selectable for scanning.

To reduce confusion, I'm going to lock this thread and make sure this post here is the last one. At this point, there is nothing that can be done to solve this issue. We are working with Google to try and come up with a quick resolution. Once we have more information, I'll follow up in this thread.
Update
I have unlocked this thread so we can use this as a single point of information and discussion for this topic

This should be fixed as of database 5705, thanks for letting us know

Ok, let's try this then please:
Download and run the Malwarebytes Support Tool. Accept the EULA and click Advanced Options on the main page. Click the Clean button and let the process finish, which will include rebooting your computer. After rebooting, the application should launch again and allow you to reinstall. If that fails, please run the Gather Logs option again and upload a new set of log files as it will contain some details around why the upgrade is failing.

Thanks. This is a known issue that should be resolved in an upcoming release.

It looks like your installation has become corrupted. I would recommend using the Clean process in the support tool above to do a clean install. Clean is under the Advanced Options section, similar to how you ran the gather logs
