If a user was infected with a file altering virus is it possible that checked in code (files containing text) to the source control could contain dangerous properties.
I ask this after this got me thinking:
Installing a new version of the operating system over the compromised operating is not a good solution as files may have been altered that could affect the new system. Even copying business critical information from a compromised system is a risk as that data may have been altered in some manner by use of the backdoor.
If so how would one clean up the code base?
