On-Access Scan

On-Access Scan prompt out this few days with the same threat detected. which is the Windows App that been set in policy define as potentially unwanted program. My question is why we did not access the App and yet it still prompt detected a threat at On-Access Scan ? Thank you, William

Re: On-Access Scan

@nwchong I assume that you are using ENS and if that is the cause I would like you to set exclusions for that particular application. Check if the policy is set correctly for the PUP.

On the other hand, I would like you to submit the sample to McAfee and obtain a negative extra DAT.

I would also like you to go through the KB article KB88482#OAS

Re: On-Access Scan

yes, I am using ENS and we have set the policy at EPO to restrict most of the Windows default App.  I don't want them to use the Windows App.

My question is why we did not access or open the App, the On-Access Scan still will prompt it detected ?

Second question is after ENS detected yesterday, why it still detect it today again ?

 

Thank you,

Re: On-Access Scan

@nwchong Can you please ensure that proper exclusions are set for that particular Windows Application, if not I would recommend you to set exclusions for the Windows App related process and if required exclude the path as well.

Re: On-Access Scan

Hi @nwchong 

In regards to: "My question is why we did not access the App and yet it still prompt detected a threat at On-Access Scan?"

Something on the system will have triggered a read/ write activity on the app causing it to be picked up by OAS.

Re: On-Access Scan

@nwchong As mentioned by @chealey  unless there is no trigger during I/O read write operations there will not be any issue.

I would suggest you to see if you have set any exclusions to that particular application, if so what sort of exclusion that you have added.

My personal suggestion would be to add the application related process to low risk so that you can un-check the scan during read write options. Also I would like you to exclude the complete path of the application.

Re: On-Access Scan

Hi ,

I have given few files/process exclusion in low risk process policy. I notice that these processes are still showing up when i run the profiler tool.

 

Please suggest
