Alternate Data Streams (used in NTFS file system) provides virus coders with a method of hiding rootkits (malware) on an infected machine and allows them to be executed without being detected by virus scanners. Normally ADS are not malicious, but some malware has been designed to leverage ADS to conceal itself.
StreamArmor comes with fast multi threaded ADS scanner which can recursively scan over entire system and quickly uncover all hidden streams.
With advanced auto analysis coupled with online threat verification mechanism makes StreamArmor the best tool available in the market for eradicating the evil streams.
StreamArmor (portable, freeware) is very simple to use. Just rum, select a drive and click Scan button. It can be downloaded from here.
