Why do Trend Micro Housecall and Malwarebytes finish scanning so quickly?

Hi everyone,


I suspect that my Macbook Pro has been compromised and infected. I ran Trend Micro Housecall and Malwarebytes, and both scans indicated that my computer wasn't infected with the malicious code they're designed to look for. However, they both also finished scanning incredibly quickly - so quickly that it made me wonder


The Housecall scan finished in about 35 seconds, and the Malwarebytes scan finished in under 10. Is it normal for these scans to finish so quickly? I'm using about 206 of 500 GB


Thanks for your help

Malwarebytes Anti-Malware for Mac is not designed to look at every file on your hard drive and compare it to every rule in the signature database, like traditional anti-virus scanners. It is looking for specific patterns in specific places to find and remove any installed malware, adware or PUPs (Potentially Unwanted Programs). Because of this, scans are quick and efficient, but that doesn't mean they're ineffective.


I can't speak for the TrendMicro product.

I apologize for the late response to this thread.


I have reason to believe that someone may intentionally be trying to monitor me. They may've had direct access to my computer and/or router


I have been seeing suspicious code in the console. Code such as:

Any insight as to what this code means would be greatly appreciated

Thank you for your reply. I have two questions:


1. Are you sure I should uninstall Avast? I was told that it was the best Anti-Virus for Mac, and that despite common thought, Macs are susceptible to infiltration and do need protection


2. Do you notice anything suspicious with the code? Or just Avast interfering with my computer's functioning


Thanks again
