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.
