Trend Micro slows down Canon scanning to o much

Hello, in the last 4 weeks my Canon flatbed scanner (Lide 400) has been unbearably slow (took 40 secs to display the scanned image). After trying EVERYTHING I solved the problem instantly after I switched off Micro Trend (Maximum) Security. 

Is this a known issue? ARe you able to solve it or should I continuing disconnecting Micro Tren each time?

I want to stress that my PDF scans are average size and the problem has never occurred before in my past 10 years and more Trend Micro subscription
