<<< Well again this is my personal expeirence and based on that..yes I have not found it detecting or cleaning Infected files. >>>
I think I have been misunderstood above.
When I say NPE is not detecting or cleaning infected files it does not mean it is not removing threats or Rootkits or any type of malware.
NPE WILL remove the Rootkit/Malware or any active threat file from your system. After a NPE scan it makes sure your system is no more infected.
However the side affect that a virus does like infecting exe's. It will not clean those exe's it will only removethe main threat on the system which is infecting the exe's
You have to run a Scan from SEP to clean these exe's.
NPE has been my favourite from a Long time I use it where a threat doesn't allow me to install SEP or where SEP has been corrupted because of a threat.
Last time when I used this on a machine it cleaned my machine where GMER etc had failed to clean.
Again NPE is not a Antivirus it should only be used where you are not able to Use SEP. It is not a replacement of Antivirus.
