Also maybe add a time frame to how long it will take to scan the external hard drive which is huge, might have given me better idea of how long it will take. My only advice for the software company is to display the entire folder link that is infected in a display so I didn’t have to take a pic of the extended link with my camera and trace it back to infected files. I was very surprised at how fast, easy and uncomplicated this process was. I couldn't figure out how to delete from Time Machine so I wrote tech support and they gave me easy instructions and they were very quick to respond. Led me to buy this Virus software and through a VERY EASY and CLEAN interface, it found all 6 viruses! I checked on my Time machine backup and it found the virus on that external hard drive too. Had a glitch on my MBP and knew it was from downloading one of those stupid Adobe Flash updates without really examining it.
