You may be asked to insert your flash drive / other USB drives.
Scan and clean will take place and program will sometimes flash
Reboot computer when program finishes
Flash_Disinfector creates a hidden folder - autorun.inf - in each partition and every USB drive that was plugged in to the program. Don’t delete this folder…it is there to help protect your drives from future infection.
You will still need to cleanyour computer if it is infected.
To prevent infections from USB drives, you can install USB Firewall before using any USB drive. I think it’s better than the changes produced by Flash Disinfector.
