Appologies if this is the wrong place to ask this question.
I have/had a computer infected with ransomware. I have just used a linux live cd and used the command
dd if=/dev/zero of=/dev/sda bs=1MB to wipe the hard drive (I have backups of my work). When that command completes, it outputs:
dd: error writing '/dev/sda': No space left on device 238476+0 records in 238475+0 records out 250059350016 bytes (250 GB, 233 GiB) copied, 2193.65 s 114 MB/s
Is that enough to ensure the ransomware has been removed, or do I need to look elsewhere too to ensure all traces of it have gone?
The computer was a Windows 7 machine.
