can’t judge, but I tell you it’s a high chance nobody ever though about hacking you. If you had something valuable lost then you could say they had targeted it. But deleting Blueprints, moving files around and such isn’t something a hacker would put time and effort to do so.
If you are after a security software, I have KIS and I’m happy with it. It notifies me whenever it blocks a possible hack, key logger, etc etc. The protection is strong compared to whatever other security software I have used.
Hope that helps.
