Cannot update

Recommended Posts

I have Malwarebytes free version set up from V1.75.0.1300.exe.

It installs OK, updates and allows scans to take place. Opening thereafter, the update panel shows that the "current database version" has reverted to zero. The date is 01/01/1601 01.00.00. The database version is V0.00.00.00 and the fingerprints loaded are 0. Checking for updates it tells me I have the latest version.

I have reinstalled a number of times and it continuous to do this, often after I have connected to the internet.

Any suggestions how I can preserve my database and update it without loosing it all and having to reinstall?

Hello and :welcome:

Sorry your having issues with Malwarebytes.... please provide the logs below so someone can review them and see if we can figure out what's going on.

Please run the tools below and ATTACH (do not copy and paste) the logs so someone can better assist you.

Please post an mbam-check log:

Sorry you are still having trouble.

Sometimes malware and other problems can prevent MBAM from installing and working correctly.

We can't do the in-depth scanning and troubleshooting for this in this particular section of the forum.
So, until noknojon returns or one of the staff has a chance to weigh in, I would suggest that you please follow his recommendations in his earlier reply, as described here: Available Assistance For Possibly Infected Computers.
A malware analyst will guide you for free through the cleanup process and will assist you with getting MBAM working properly on your system.

Thanks for your patience,
