View Full Version : Uknown ADS - Do I need to worry about JPEGs and PDFs?

2013-03-19, 15:02
Hi all,

Please have a look at my scan log below. It's coming up with Unknown ADS for several items, most of which are JPEG images and PDFs.

Do I need to worry about these files?

There's also a hidden file D":\WINDOWS\system32\termcap" which seems a bit more suspicious...

Would you say that there is anything suspicious looking in these results?

That is nothing to worry.

termcap is a software library which enables programs to send control strings to terminals.

The other found items are only pictures.

If you get ‘No admin in ACL’ this threads in our forum should help explaining:
Unknown ADS and no Admn in ACL what is good and what is bad??? (http://forums.spybot.info/showthread.php?t=27446)

Malware sometimes uses rootkit technology to hide itself at system level.
This makes it undetectable by standard tools. Our plugins help Spybot – Search & Destroy to detect this form of malware.
Our Rootkit Scanner tool shows anything that uses certain rootkit technologies. But items with rootkit properties detected here are not necessarily malware. Sometimes, legit software uses rootkit technologies to hide registration data or other things it does not want the user to see in any case. So please keep in mind that the Rootkit Scanner only flags suspicious stuff, not identifying just bad stuff.

Best regards

Thanks for your prompt reply Sandra.

I did check out the two threads you mentioned before posting my question and I thought you might like to know why I didn't find them that useful:

"Unknown ADS and no Admn in ACL what is good and what is bad???"
I scanned through both pages of this but struggled to find a simple answer to what "Unknown ADS" and "No admin in ACL" mean.

PepiMK's response probably said it best but it was still too technical for me. I take it that "Unknown ADS" simply means that its a stream that Spybot doesn't recognise, which is not uncommon since there are so many. I still don't know what a stream actually does though :)

"2 Simple, Quick Questions"
I get a "Jimbo010101, you do not have permission to access this page." error on the second link.

Anyway, I got my answer promptly and eloquently so thanks again! :)

Sorry, the second link - which also should have helped to clarify - was to the Business forum, which you can't access.

ADS means unknown Alternate Data Streams (ADS).
In Microsoft's NTFS file system forks (http://en.wikipedia.org/wiki/Fork_%28file_system%29) are known as Alternate Data Streams (ADS) (http://en.wikipedia.org/wiki/NTFS#Alternate_data_streams_.28ADS.29).
Alternate data streams allow more than one data stream to be associated with a filename, using the filename format "filename:streamname" (e.g., "text.txt:extrastream"). Alternate streams are not listed in Windows Explorer, and their size is not included in the file's size.

That's why they have been found in the RootAlyzer scan, as they do not have the usual format or size as a normal file, plus they are hidden.

But nothing to worry, your's are OK. ;)
