USB Anti-Virus?


Recommended Posts

I wonder if there is any portable Anti-Virus that can be installed on USB Flash devices,to protect it from viruses if for example plugged into PC which doesn't have Anti-Virus and probably infected,to make sure they won't infect the Flash and the files in it.

You can Scan the USB device while it's pluged-in, with all AV programs,

but I've Not seen any software that can be put on the device, to secure it.


AV programs have to be loaded into computer-memory and run constantly in background.

Activated during Data-transfers.

Just download these portable utilities and update them before use on an infected computer.

Sorry, but from what I've read None of those are a Full Virus protection software.

They protect only for simple Malware types and can not be updated regularly,

as required by good Virus protection programs. :sad:


They are similar to the Malware-Remover utility in ASC, which is also not full Virus protection.

Unfortunately, it is not. This program simply disables the autorun function so that the removable device will not be accessed and so preventing infection.


I am on Toppacks side on this one. An antivirus on a removable device would require the removable device to have an OS installed. Flash Drives and USB,s would not have the capacity to do this. An antivirus program can be loaded on to a removable device, but that antivirus program would rely on the OS of the pc into which it is plugged, to run it.
