Password guessing on a PC

What happened

Many wrong Windows passwords were tried on this PC. Someone at the keyboard, or a program on the network, is trying to get in.

How serious

Serious: deal with it today.

Steps: Windows PC

  1. Ask the person at that PC what they were doing at that time (installing something, a link in an email, a USB stick).

  2. Change the passwords used on that PC (Windows, Microsoft 365 or Google, banking) from ANOTHER, clean device.

  3. Run a deep scan: Windows Security → Virus & threat protection → Scan options → Microsoft Defender Antivirus (offline scan) → Scan now. The PC restarts.

How to check it’s fixed

Fixed when the deep scan finds nothing, protection is on again and Ojava shows the PC as healthy for 24 hours.

When to call your IT provider

Call your IT provider today, before using the PC again for work.
