The WindowsRecoveryCleaner or Iostream.exe Miner is a Trojan that uses your computer to mine for digital currency without your permission. This program is typically installed in adware bundles that pretend to game cracks, cheats, or key generators.
The Iostream.exe miner is actually renamed XMRig executable that when started will use all of the available CPU power of the computer to mine for Monero. The program is started through the Windows Scheduled Task shown below called WindowsRecoveryCleaner that is launched automatically when a user logs into the computer.
What is particularly worrisome about this infection is that it will use the entire CPU’s processing power indefinitely. This will cause your CPU to run at very hot temperatures for extended periods of time, which could shorten the life of the CPU.
As there is no outward indication that the program is running, here is a list of symptoms that a user can use to determine if they are infected with the WindowsRecoveryCleaner or Iostream.exe Miner:
- You will see the Iostream.exe process using almost 80% or more of CPU.
- A schedule task will be present called WindowsRecoveryCleaner
- Attrib.exe is running with high cpu utilization but closes the second you open Task Manager. Attrib.exe is legitimate and should not be deleted.
- Programs don’t launch as quickly.
- General slowness when using the computer.
