How do make sure a trojan how be 100% remove from my Macbook pro?

Question

3 days a go my Kaspersky security had found a two trojans on my Macbook pro I use Kaspersky security on my system. I all so put up a screenshot from my Kaspersky reports to show you guys where the two trojans where found on my system. But I still believe the trojans or hiding deep in my system now because every time I do a full scan every night when the scan is nearly finished a folder pops up on my desktop call boot OX stays onscreen for 2 seconds and disappears again. What can I do to make sure my Mac is 100% clean?

Answer 1

Those aren't trojans. Those are files your AV software cannot identify, so it labels them as infected. This term relates to a virus, not a trojan.

If you require anti-virus protection I recommend using VirusBarrier Express or Dr. Web Light, both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
