Cisco Talos MBR Filter Driver

License: GNU General Public License v2.0
MBRFilter This is a simple disk filter based on Microsoft's diskperf and classpnp example drivers. The goal of this filter is to prevent writing to Sector 0 on disks. This is useful to prevent malware that overwrites the MBR like Petya. This driver will prevent writes to sector 0 on all drives. This can cause an issue when initializing a new disk in the Disk Management application. Hit 'Cancel' when asks you to write to the MBR/GPT and it should work as expected. Alternatively, if OK was clicked, then quitting and restarting the application will allow partitoning/formatting. To install: right click the inf file, select 'install' and reboot when prompted. To access sector 0 on drive 0: boot into Safe Mode. To compile: make sure to set: MBRFilter properties -> Configuration properties -> Driver Signing -> General Sign mode: Test Sign Test certificate: generate or select one from your store. To remove MBRFilter, follow these steps: - Remove the line MBRFilter from the UpperFilters registry key in (only remove MBRFilter, there might be other disk drivers here): HKLM\System\CurrentControlSet\Control\Class\{4d36e967-e325-11ce-bfc1-08002be10318} - Reboot AccessMBR Simple program to read sector 0 on Physical drive 0 and write that sector back. Used as a testing program for MBRFilter. This overwrites your MBR, it will restore it once it's done. Nevertheless: USE WITH CAUTION.

If I have MBRFilter running and connect an USB drive, a popup says "drive need to be scanned for errors".
When I choose "check and fix errors", the dialog says the error is fixed and I close the dialog.
After a short amount of time, the "drive need to be scanned for errors" dialog popups again.
Hi,
is there a plan to translate the few strings of MBRFilter to other languages? I could do this for German.
Best regards,
Ettore
Could you provide an up-to-date release for people that don't like having to install visual studio just to compile one app. Your last (only) release is from August.

Receiving reports that some people are having issues with startup repair running after installing this driver.
The 64-bit version of it caused the OS to freeze at the Windows Logo when starting up. I think it is an issue with it and the RAM Disk driver that I have installed (which is Ultra RAMDisk - http://www.ultraramdisk.com).
