Does anyone here having an adware spike going to

Our ZS risk score is spiking going to which is classified as an adware/spyware advanced threat, our current AV solution doesn’t detect any on the machine. Tried Malwarebytes as well and machine is clean. We submitted a ticket to Zscaler support and verified it’s true positive.

Is there anyone here having the same issue, and resolved this annoying incident?

Thanks in advance!
