Is there any AV tool I can use on a USB and clean infected computers?

[slicksilver]

I gotta take care of 8 computers. All of them are in retail locations and do not have internet. Almost all the users copy files to usb drives and back to the PC. Is there a AV tool I can send to them to clean their computers every now and then?

Thanks

If the computers can boot from USB, then you could make a bootable USB device using Kaspersky Rescue CD: http://support.kaspersky.com/us/viruses/rescuedisk/main?qid=208286083

If they have Admin privileges on the systems in question, then you could also use Kaspersky's virus-removal tool from within Windows: http://www.kaspersky.com/free-virus-removal-tool


For a system with no Internet access, also consider addressing the likely infection methods proactively.

1. arbitrarily disable AutoRun completely. http://www.mechbgon.com/build/autoplay.html

2. enable the Windows Firewall if it isn't already.

3. lock down the Admin privileges. Anyone using the computer should be on a Standard User (non-Admin) user account.

4. lock down the execution of executables using either Family Safety, or Software Restriction Policy: http://www.mechbgon.com/srp

5. it wouldn't hurt to install EMET 4.0, a free utility from Microsoft that makes it harder to exploit vulnerabilities in Windows and other software.

Kaspersky rescue disk is for CDs. You would need to make the USB boottable in order for you to use it.

Edit, just seen Mech's post. LOL!

I wonder if you can use kaspersky's Rescue2USB.exe to create a boottable USB stick of Avira AntiVir Rescue System? I shall try it and report back.

Kaspersky's Rescue2USB.exe wouldn't work with Avira as it said the destination was too small but it was a 4GB drive so not sure what to make of that I tried FAT 16 as well as NTFS and got the same error.

I did however find instructions to create an Avira USB stick.

Thank you all.

Gotta be careful with USB sticks for this. Make sure you're going the bootable route and not just sticking AV/malware software on a USB. It's entirely possible to have your "Rescue Tools" usb get infected itself just by plugging it into a live infected system.
