I saw in few topics that you recommend to reinstall once compromised system, so i wish to ask why is reinstall recommended solution? Sorry if asked before...
Firstly, how you describe compromised system (I assume, compromised by malware)?
- compromised by malware that instert one file (for example %appdata% location) and corresponding reg entry --- Fake AV
- middle severe malware (install process/driver, little harder to remove), for example Conficker that has advanced spreading tehniques
- top malware (zero access, necurs, tdss), that shuts down few important services, mess with drivers, install hidden partition etc.
It is not always the case that malware use exploit and sneak by undetected, infecting the system. In majority of cases, user is one that open the doors, clicking on unknow links, using infected usb drive etc.
Final word, majority of viruses are able to completely remove and to restore system like it was, so I am asking why you recommend reistall? Thanks...
