Norton 360 Smart Scan says I have an advanced issue but doesn’t tell me what it is. How do I get this information?
Norton 360 v 26.4.0
Tahoe 26.4.1
1 advanced issue found

Hello @StephenT_Mills

That screenshot is actually very revealing.

Your Smart Scan is not showing a hidden malware problem — it’s showing a UI/design flaw in Norton v26.

Notice:

• “0 malware threats found”
• “8.47 GB to free up”
• “1 advanced issue found”

But Norton provides:

• no “Fix Now”
• no expandable detail
• no category
• no drill-down link

That strongly suggests one of these:

• a missing/failed upsell module load
• a broken recommendation tile
• an unconfigured optional feature Norton considers “advanced”
• or a UI rendering bug

The important thing:
this does not look like an actual detected threat.

Also telling:
the page below immediately pivots into:

• Smart Scan reminders
• “Protect up to 48 more devices”

That’s typical of Norton’s newer “engagement” UI flow rather than a serious security alert.

The “8.47 GB to free up” line is almost certainly:

• cache files
• logs
• downloads
• local snapshots
• browser leftovers

—not dangerous.

The real clue is that the “advanced issue” line is isolated with no remediation controls. In older Norton builds, real actionable findings usually had:

• Review
• Resolve
• Fix Now
• Details

I suspect the backend recommendation object exists but the front-end tile failed to render.

Things you can try:

1. Click directly on “1 advanced issue found”
   Sometimes the text itself is clickable even when nothing visually indicates it.

2. Open Activity / History immediately after the scan
   Look for entries like:

• Recommendation generated
• Advanced issue detected
• Performance issue
• Privacy recommendation

3. Check whether any optional modules are disabled
   Common culprits:

• VPN
• Safe Web extension
• Cloud Backup
• Privacy Monitor
• Software Updater

4. Run another Smart Scan after reboot
   There’s a decent chance the phantom issue disappears.

5. Ignore it if:

• Device Security shows green
• Real-Time Protection is enabled
• Definitions are current
• No unresolved alerts elsewhere

Because based on that screenshot, I would not interpret this as evidence of compromise or malware. It looks much more like Norton v26’s increasingly opaque recommendation system/UI behavior.

There is literally no disclosure UI attached to the “1 advanced issue found” line.

No:

• chevron
• details button
• fix button
• hyperlink
• expansion pane
• category card

That makes this look even more like either:

1. a broken Smart Scan recommendation renderer, or
2. Norton intentionally abstracting a low-priority “optimization” issue without explanation.

And because:

• malware = 0
• there is no urgent red banner
• no quarantine action
• no “device at risk”
• no security module failure shown

…I would not interpret this as an actual active security problem.

My best guess from experience with recent Norton builds:

The “advanced issue” is probably one of these hidden advisory items:

• VPN not enabled
• Safe Web browser extension absent
• Cloud Backup not configured
• Privacy Monitor inactive
• Software Updater recommendation
• Device optimization recommendation
• Norton Utilities / Driver Updater marketing hook

especially since Smart Scan increasingly blends:

• security
• cleanup
• feature adoption
• subscription engagement

into one result screen.

The UI behavior here honestly resembles a partially failed web-style component load. Norton’s newer interfaces are heavily service/UI driven compared to the older native-style layouts.

What I would do personally:

• Verify Device Security shows green
• Verify Auto-Protect is enabled
• Verify definitions are current
• Ignore the Smart Scan “advanced issue” unless another module shows a concrete warning

You can also try this specific test:

Run:

• Smart Scan
• then immediately disconnect Internet
• reopen Norton History/Activity

Sometimes the missing recommendation tile suddenly appears in history because the cloud-fed advisory component already cached locally.

But overall, your screenshots do not suggest malware or compromise. They suggest Norton v26 being vague and possibly buggy.

Tahoe 26.4/26.4.1 clearly introduced a number of behavioral and interoperability regressions that affected third-party software, networking, UI components, and security-related integrations.

A few things stand out:

• Apple changed lower-level networking/security behavior in 26.4
• content filter extensions had known issues in 26.4.1
• multiple developers/users reported UI and compatibility oddities after 26.4
• several problems reportedly improved again in 26.5 betas/releases

And Norton on macOS is deeply tied into:

• network extensions
• content filtering
• browser integration
• system permissions
• background services
• cloud-fed UI modules

So if Tahoe changed:

• extension timing
• permissions behavior
• rendering frameworks
• networking APIs
• sandbox behavior

…then a weird “phantom advanced issue” in Smart Scan is very plausible.

Your screenshot especially looks like:

• the scan engine completed,
• the advisory count incremented,
• but the detail component failed to populate/render.

That is consistent with the kind of partial incompatibility bugs people have been reporting across other apps on Tahoe 26.4.x.

The reassuring part:

• Norton still reports zero malware
• the scan completed successfully
• there is no broken protection warning
• there is no “at risk” state

So this feels more like:

• UI integration trouble
• cloud recommendation fetch failure
• or unsupported/unfinished compatibility edge cases

—not evidence of infection.

Honestly, with new macOS releases, security software vendors are often playing catch-up for a while. Norton, CrowdStrike, SentinelOne, VPN vendors, audio vendors, NAS vendors — they all tend to hit rough edges after Apple changes internals. The Tahoe 26.4 cycle especially seems to have been noisy from a compatibility standpoint.
