USB storage connected

What happened

A USB stick or disk was connected. Usually harmless; it can bring in malware or carry data out.

How serious

Low to serious, depending on who plugged it in and what was copied.

Steps: Windows PC

  1. Find out who plugged in the USB storage and why. If nobody knows, keep the stick away from other PCs and give it to your IT provider.

  2. 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.
