Software That Will Remove AV Security Suite
MalwareBytes' Anti-Malware is one of the few pieces of software I know of that has drive selection. There are others out there I just grabbed this one first and it worked. Why change something that works right? Plug the external hard drive into the other computer. Start up MalwareBytes and follow the steps below. The screen shots below are from a different trojan removal. But the steps are the same. Image 7 is the quarantine and the circled infections are the AV Security Suite infections. The names will differ because it uses a random name for its executable names.
You can find the screen shots below this paragraph.
Select "Perform Full Scan" and hit the scan button.(Image 1)
Select the right drive. Click the Scan Button.(Image 2)
The progress window will pop-up and you can follow the scan real-time.(Image 3)
The scan is complete. However nothing was removed yet. Click "OK" and hit "Show Results".(Image 4)
The Results are shown. Make sure all infections are selected and click "Remove Selected".(image 5)
MalwareBytes moves the files to the quarantine and deletes files. The Log window will pop-up make sure the infections are in the log and it says: "Quarantined and Deleted Successfully".(Image 6)
Check the quarantine and make sure the infections are in there.(Image 7)
Click Exit. The Infections are now removed. Move on to the next drive if you have more then one drive to scan.(Image 8)
Now you are ready too put the hard drive(s) back in the computer or laptop.
