AlternateStreamView is a small and portable application by NirSoft which can detect and locate alternate data streams on your system.
What an alternate stream is, is a part of the NTFS filesystem. While most of them are harmless, some malicious applications can take advantage of them and execute them without the knowledge of the owner.
This program will scan your system for them and allow you to delete them or export them to an external file like HTML, XML or CSV. What it doesn't do is detect whether they are malware, so that is up to the administrator.
AlternateStreamView is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from file search software without restrictions. AlternateStreamView 1.54 is available to all software users as a free download (Freeware).
Compatibility with this alternate stream finder software may vary, but will generally run fine under Microsoft Windows 10, 8, 8.1, 7, Vista and XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from NirSoft Freeware.
We have tested AlternateStreamView 1.54 against malware with several different programs. We certify that this program is clean of viruses, malware and trojans. [Read more]
