Please find I have updated.

Hi,

       In this case the issue seems to be with the Network Threat Protection feature on these clients, we would request you to uninstall the Network Threat Protection feature and then check for the performance of the system. Please keep us updated about the status after the uninstall of NTP.

Try by reinstalling NTP....

Sandeep,

We are using NTP since a year and from yesterday we face the issue.

You may also check for any recent policy
changes...

Aravind..,

We have not done any kind of changes in SEPM.

 Is a a known feature of SEP. If you have any Firewall Policy applied for applications it will allow the applications but once the application has changed ( updated ) the hash changes so again it will ask you whether you want to allow it or not.

Do you have set the firewall policy in ASK mode?
or are these clients in Client Mode

Vikram,

Thanks for your comments,

This all policy of firewall are default and we are not using application blocking.

I know this could be asked if you add any fingerprints to block application but we have not added anything.

Can u try by uninstalling any recently
installed os patches...

Also check any version change
happens for your applications...

 This is not due to application control but the Firewall policy for Application.
And also are your clients in Client Mode--as then local firewall policy will overrule and there is a default firewall policy to ask before allowing a application.

I am talking about these two policies as show in the pic.

I have attached my current policy of my SEPM.

Please suggest if need to change anything.

 Are you clients in Client Control mode ir Server Control Mode?

Client Control Mode.
