I have the same problem as another user on this forum but they never finished replying to the thread, and the moderator closed it.
He stopped replying as the fix was almost complete for everyone to see but the link to the txt file the moderator said needed to be used to fix the problem is no longer working.
This is the original thread:
https://forums.malwarebytes.com/topic/234870-chrome-extension-coming-back-after-fresh-install-of-chrome/
Since we most likely have different setups and in order to save some time I'd be willing to try the fix the moderator suggested for that user without needing him to go through my log files and setup (also saving me the time of creating them).
The only extra info I can offer is that I use IOBit Uninstaller to remove the plug-in as well since when you remove it from Chrome via the settings/Extensions menu you won't see it in Chrome any longer but it shows up in IOBit under Plug-Ins. No matter what though, some mysterious "other program" always re-installs the extension whether I use IOBit or Chrome Extension settings page to remove it.
A terrible and deceitful plug-in that clearly operates in extreme bad faith/taste, no idea how Chrome still allows this extension in their store. Thanks in advance for the help, it's appreciated.
