Avast 8 desktop result different from Avast on Virustotal

I’ve been having a problem with a Nirsoft utility called Remote Desktop Passview found here:

http://www.nirsoft.net/utils/remote_desktop_password.html

It’s included in his Nirsoft launcher which is an all-in-one program of all of Nirsoft’s Utilities. Malwarebytes issues a message once a day stating the program is trying to start which is strange because I’m not starting it. (A message on the Malwarebytes forum indicates that this is probably because of the Superfetch service in Windows 7). Malwarebytes won’t even let me check its properties without trying to quarantine the file as it issues a “password.tool” warning. Obviously, that’s what it is as Nirsoft has a host of password tools on his site. I’m just going to have to add it to the Malwarebytes ignore list.

What’s even more puzzling is that my desktop version of Avast 8 scans it and says it’s clean, but the Avast engine on Virustotal.com has the following scan result:
Win32:PSWtool-V [PUP]

However, the Avast engine on Jotti also says it’s clean!

Many AV programs give the file it’s own password tool classification, while G-Data and F-Secure even have it classified as a Nirsoft app.

My current version is:
Avast v 8.0.1482
Engine & def v130305-1

Why does my desktop version of Avast reflect the file as clean while Virustotal’s version of Avast didn’t? The file can be download from the Nirsoft link above.

PUP = not a virus/ Possible Unwanted Program
so avast is telling you that you have a program that can be used for good or bad if abused
so you need to know what it is, who installed it, before you decide if you want it or not

PUP scan is default off in quick/full scan…but default on in boot scan

the scan engine on VT is not exactely the same as the one in your comp, you find more info about that on the VT
website

Malwarebytes also have PUP detection and one called PUM
Possible Unwanted Modification…it will warn you about firewall / windows security senter turned off. etc etc
was it you that turned off the firewall or malware? :wink:
