Against what AppGuard does not protect?

Against what kind of malware or anything else AppGuard does not protect?
And is it safe to have it alone on the computer with no additional software?

 

If you assume the system in question is clean to begin with AppGuard on lockdown for example is very good at preventing drive-by style attacks because it prevents execution from any area guarded apps such as browsers can write to. It also helps prevent exploits by protecting the memory space of gaurded apps and prevents them from modifying the memory space of other apps.

It does not help with social engineering type attacks because it makes no judgement on whether a file is good or bad it simply blocks execution in user space. If you decide to reduce AppGuard's protection to install a malicious file you've been fooled into believing is legitimate it won't tell you otherwise. It is also not a firewall so wont protect against things traditinally associated with network traffic monitoring tools.

The MBR guard also does a good job as does the USB/network drive anti-execution role.

If the system is infected to begin with and that infection has escaped user space AppGuard will be of limited use. If that malicious file is executing in user space AppGuard will prevent it.

I have used it on its own successfully with on demand scanners and back-ups in place just in case. Only you will know if it is 'enough' for you.
