- To move multiple files to Quarantine, use the check boxes to select each file, then click Resolve Selected.
- To move all files to Quarantine, click the check box at the top of the list, then click Resolve Selected.
- After resolving the detected threats, or if no threats are found, click Done to return to Scan Central. Alternatively, click the back arrow, then Ignore, to ignore detected threats and return to Scan Central.
