Should I change folder permissions: Possible dangers?
Greetings TechSupport friends,
[note: this is not a question about virus/trojan etc.]
Just to give some background to my problem:
I have an infected hard drive. The only way for me to remove the infection is to take out the drive, connect it as a slave to a clean computer and remove the offending files manually.
The reason I have to do this is because the infection (a ransomware) has taken over the whole screen; even when I boot up in 'safe mode with command-prompt' I cannot access the command-prompt window, and therefore cannot get into regedit or anything else for that matter to remove the offending files.
I am the only user on that system, so I can't log off (and the ransomware doesn't allow me to anyway).
Now, when I connect the infected drive to a clean system, I am unable to access the folder [*drive*\Documents and Settings\*user folder*\], as I am confronted with an 'access denied' message.
I understand that it is possible to change the permissions pertaining to this folder, so that I can access it from my other system and then be able to delete the offending files and restore functionality to that user area.
My question, then, is: If I change the folder permissions and remove the infection, upon reconnecting the drive to its original system will I still be able to log on to that user area (seeing as the permissions of the folder have now been changed)?
Thanks in advance for any suggestions you may be able to offer.
