Hi,
I have the same kind of result on my computer:File:"Unknown ADS","SomeFileName:$CmdTcID:$DATA"
I can see it as well through the "streams.exe" tool from Sysinternals (https://technet.microsoft.com/en-au/...rnals/bb545046).
Comodo Internet Security 8 (obviously at least up to my 8.2.0.4508 installed release, but apparently not CIS 7 and previous) is indeed creating such an alternate data stream attached to some or many files, for some reason (probably a bug), see:or:or search Comodo's or Spybot's forum for "CmdTcID".
So if your ADS are effectively due to Comodo, this shouldn't be a big issue (to be confirmed: this is only my personal understanding of our situation).
(In order to be sure it's due to Comodo, you might have to find the way to create a new file that systematicaly ends with $CmdTcID in its ADS, then temporarily disable Comodo 8 or replace it with version 7, and then re-create a new file in the same way and check with streams.exe that its ADS does not contain $CmdTcID)
But as mentioned in one of the above posts:When you copy files from a NTFS file system to a USB flash-drive (FAT),
You may receive the Easter egg "The file Setup.exe has properties that can't be copied to the new location. Do you wish to continue?"
and by the time you remember it's all about last year Comodo's ADS, you spent minutes (or hours...) wondering what the hell is going on here...
Any other side effect anybody can think of?
It seems that we have to wait for a fix of Comodo IS, and even once delivered we might still have to remove these ADS through a tool such as the aforementioned streams.exe - but this one removes all the "ADS fields" (?) of a file (there might be other "ADS fields" than $CmdTcID related to a given file), unless a recent release addressed this. The first one who finds a tool that easily, automatically remove a given "field" (?) in the ADS of all the files in a directory and all its sub-directories wins the right to post its URL here. And even once found and succesfully run, according to some of these posts on Comodo's forum it might not prevent Comodo to re-create this very ADS on the very same files...
Regards.
