Any info on this?

Attached is the screenshot

Sometimes when I copy installers from system to USB, I get the window in the screenshot.

Any info?

 

What filesystem is the USB device? Also does it happen with any file or just executables?

 

Do you have a anti-virus program that uses a cache system to speed up scans? I get this sometimes with BitDefender, it basically means the security app uses NTFS ADS (Alternate Data Streams) tags on files it has already scanned to speed up scanning, when then copying the files over to USB stick formatted in FAT32 you get that message, it just means that it can't copy over the ADS tags.

Safe to ignore, your files are ok

 

I didn't know BitDefender is using ADS. Does it remove them when uninstalled? I remember Kaspersky was using them also years ago and it has caused a lot of users angry when they realized that ADS remained after KAV uninstall.

 

Maybe some restriction on external devices because of settings in apps like SpyShelter, AG or similar?

 

Yes, Bitdefender Free is installed on the system.

So files are ok.

The original file properties shows 6 tabs but the copied file properties shows 4 tabs, thats fine?
But yes the digital signtaure is ok.

 

I'm not 100% sure but they do have a scan cache functionality in the AV engine, only times I got the message that narenbisht gets was with Bitdefender AV+ 2013-2014 installed & copying software installers to USB stick.

Maybe the separate Bitdefender uninstall tool removes them, it certainly takes it time

 

Yeah your files are fine, just the ADS tags can't be copied to a FAT32 formatted USB drive as FAT32 doesn't support them.

 

Streams (http://technet.microsoft.com/en-gb/sysinternals/bb897440) can be used to check if those files have ADS attached. It enables you to delete those streams also
