One of the common method that virus use to spread themselves is through USB flash drives. All they need to do is create an autorun.inf file at the root of the USB flash drive and points it to a malicious executable file. When the USB flash drive is plugged in to a computer that is running Windows, double clicking the drive letter from My Computer will immediately process the autorun.inf file and launching the virus…
People are advised NOT to access the USB flash drive from My Computer. Use the shortcut key [Win + E] to open up Windows Explorer then go to the USB flash drive letter to scan the USB flash drive right after plugging in. It’s not perfect, but at least an updated antivirus program will protect you from most viruses.
VirusScan Enterprise 8.7i and later allows you to take action when using a right-click Scan. VirusScan 8.5i and 8.0i do not have an option to configure the default VirusScan Enterprise right-click Scan for threats... settings.
When the scan starts, there is an option to click Properties, but changing the Primary Action from Continue scanning to another option such as Clean or Delete will not affect the action taken by the right-click scan. After changing the properties, these can only be saved as a new On-Demand Scan task.
In Windows Explorer, select one or more of the following:
Use the shortcut key [Win + E] to open up Windows Explorer
Specific drives (eg - F: My_USB_drive)
... or specific directories
... or individual files
Right-click and select Scan for threats... to scan the relevant object(s) using the default scan settings.
Note: You only need one suitable updated antivirus product, at least two anti-spyware products. Some suitable free anti-spyware software include Spybot S&D, Ad-Aware Free Anti-Malware and Malwarebytes. Malwarebytes should be run in an emergency, generally. The other two products should be run on a regular basis.
