Smart UAC is a clever program developed by Security Stronghold company which automatically replaces UAC (User Account Control) from Windows Vista with a much more powerful and intellectual one.
Unlike standard UAC, Smart UAC Replacement will not disturb you with numerous alerts of the good programs you use everyday over and over again. Smart UAC remembers your choice for a given program and will allow or deny it automatically unless you haven't changed your mind or unless the program's executable has changed.
The second great thing about Smart UAC is that it has a large and regularly updated database of more than 400,000 known threats including viruses, trojans, spyware, adware, keyloggers, privacy breakers and even rootkits. Smart UAC will scan each run program and automatically determine in milliseconds if it is known malicious program or a good one without requiring you to decide it yourself as it was with standard UAC... This way you should just let Smart UAC kill programs which were identified as malicious ones - and the threat will be eliminated.
