Endpoint Security Agent High CPU After Update

- CPU usage remains high for extended periods after security update. - Device becomes sluggish and user productivity drops. - Issue may affect a cohort on same agent/signature version.

- Post-update scanning backlog or repeated scan loop. - Conflict between agent module and specific application workload. - Corrupt local cache/signature state.

Document whether the issue affects one user, multiple users, or multiple devices. Confirm exact error messages, recent changes (password reset, update, network change), and whether the same issue reproduces in web vs desktop workflows where applicable.

Confirm the user is signed in with the correct corporate account, system time is accurate, network/VPN connectivity is stable, and the application is not running in offline or limited mode.

Use the command snippets below to collect non-destructive diagnostics. Capture output in the ticket when escalation may be required. Avoid deleting profiles, cached credentials, or managed app data unless the runbook or admin approval explicitly allows it.

- Capture process CPU trend, agent version, and definition/signature timestamp. - Confirm whether CPU stabilizes after expected initial scan window. - Collect agent logs using approved support workflow. - Escalate to endpoint security team for policy/module tuning.
