VirTool:INF/Autorun.gen

Severe |Detected with Windows Defender Antivirus

Aliases: Trojan.AutorunINF.Gen (BitDefender) INF.AutoRun (Sunbelt Software)

Summary

Windows Defender detects and removes this threat.

The autorun.inffile is created by worms when they copy themselves to a local, network, or removable drive.

Some worms can spread to other PCs by infecting removable drives that you have plugged into your PC (such as USB drives or portable hard disks). If you plug those drives into another PC, the worm will infect that PC as well.

This is a common way for malware to spread. However, autorun.inf files on their own are not necessarily a sign of infection, they are also used by legitimate programs.

Use the following free Microsoft software to detect and remove this threat:

You should also run a full scan. A full scan might find other hidden malware.
