Hi there! I am new on bleeping computer.

 

Just scanned a pc with a huge amount of infected objects (about 930). Just noticed somewhere that there are about 7 partitions on the notebook, few are hidden. Mbrcheck found non-standard or infected MBR (\\.\PhysicalDrive0 - Unknown MBR code).

What do I do now? I have a full image backup. The notebook runs on windows 8.1 so combofix is a no-go.

 

Partitions

- (no name) - recovery partition 1GB

- (no name) - EFI system partition 260MB
- (no name) - OEM partition 1GB
- (no name) - recovery partition 450MB
- (no name) - recovery partition 20GB
- Windows8 C: - startup, swap, crashdump, primary
- LENOVO D: - Primary

 

 

Scanners done:

- malwarebytes

- cureit

- norton

- norman malware cleaner

- tdsskiller

- mbrcheck

 

Thanks in advance!

Just fixed the MBR by holding shift while doing a reboot through Win8. Entered commandprompt through the advanced options. Entered 'bootrec /fixmbr'. Aswmbr and mbrcheck confirmed the mbr as valid again.
