Delete the file and scan the system with up-to-date security software; do not run or distribute crack tools.

What to do now4 steps

This is a hacking tool. It is risky to keep and run, but finding it is not by itself a sign that the device is infected.

What to do

  1. Don't run it unless you got it on purpose for security testing on systems you own. Delete it, then empty the Recycle Bin.

  2. If you didn't put it on the device yourself, delete it and run a full antivirus scan: something else may have brought it.

  3. Tools like this often come with cracked or pirated software. If it came that way, treat the whole download as unsafe and scan everything it installed.

If you already ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

If you opened or installed it

Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

Threat context

How hacking tools are used

Hacking tools are programs that can switch off security software, test passwords or attack other computers. Security professionals use them on purpose; criminals also bundle them with malware.

Bottom line:Keep it only if you installed it on purpose, and check how it got onto the device if you didn't.
