Some customers report that their printer stops working after installing or enabling Trend Micro Security or Trend Micro VPN.
This post explains why this happens, when it is expected behavior, and how to restore printing safely.

Why Printing Can Stop When Trend Micro Is Enabled

Most printer issues fall into two categories:

1. Local network security controls (Firewall / Network Protection)
2. VPN‑related network isolation

These are not random bugs—they are usually the result of how operating systems and networks handle security and traffic isolation.

Scenario 1: Printer Blocked by Trend Micro Security (Firewall / Network Protection)

✅ This is expected security behavior, not a product defect
Trend Micro Security monitors local network traffic to prevent:

• Unauthorized device access
• Lateral movement by malware
• Exploits using open network ports

Many printers:

• Use open or legacy ports
• Broadcast via network discovery
• Do not authenticate traffic

Because of this, the firewall may:

• Block printer discovery
• Block print jobs
• Mark the printer as an unknown device

Common Symptoms:

• Printer appears offline
• Printer not detected on the network
• Print jobs get stuck or fail
• Printing works when Trend Micro is disabled

How Users Can Fix It Safely

1. Add the printer to the trusted network
• Ensure the network is set to Private / Home
• Avoid using Public network mode
2. Allow printer communication
• Add printer IP or application to the Exception / Allowed list
• Allow inbound/outbound local network traffic for the printer
3. Temporarily test (for diagnosis only)
• Disable Firewall briefly
• If printing works, re‑enable Firewall and configure exceptions (Do not leave protection disabled)

Scenario 2: Printer Not Working When VPN Is Enabled

⚠️ This is a known VPN limitation, not a Trend Micro bug
When a VPN is active:

• Your device traffic is routed through an encrypted tunnel
• Local network devices (like printers) may become unreachable

Common Symptoms:

• Printer works when VPN is OFF
• Printer disappears when VPN is ON
• Network printer cannot be found
• Wireless printing fails during VPN connection

How Users Can Fix It Safely

• Turn off VPN when printing to a local printer
• Use USB printing instead of network printing
• Enable split tunneling (if available) so local network traffic bypasses VPN
• Use cloud‑based printing features (if supported by the printer)

What Trend Micro Is Doing

• Improving device detection and trust flows
• Reducing false positives for common printer software
• Enhancing VPN handling during network changes
• Updating guidance so customers can configure printers safely

Trend Micro offers several apps with VPN or VPN‑based protection. However, using multiple Trend Micro apps with VPN features on the same device may cause connection or stability issues. This is because most operating systems allow only one active VPN connection at a time.

Why Issues May Occur

When more than one app tries to control a VPN, the system may disconnect the VPN, toggle it on and off, show “connected” with no internet access, or block another VPN from connecting. This behavior is controlled by the operating system and is not unique to Trend Micro.

Trend Micro Apps That Use VPN Technology

Full VPN apps:

• Trend Micro VPN
• Trend Micro Mobile Security (Web Guard feature)

VPN‑based protection apps:

• Mobile Security (iOS Web Guard / Safe Browsing)
• ScamCheck
• ID Protection (network‑level protection)

Best Practices

• Use only one VPN feature at a time
• Choose which app controls your VPN based on your priority (privacy, safe browsing, or identity protection)
• Check VPN permissions and remove duplicate VPN profiles (especially on mobile)
• Restart the device after changing VPN settings
• Keep all Trend Micro apps and your OS up to date

Key Takeaway

VPN issues usually happen when multiple apps compete for VPN control. Using a single VPN feature ensures better stability and performance.

Planning a trip with Cathay Pacific and want to check your baggage allowance? You’re not alone as it’s one of the most searched travel questions online. But while searching, watch out: scammers are creating fake airline websites and customer service pages to trick travelers.

Why This Matters

Scammers know that people often search for things like "Cathay Pacific baggage policy" or "how much luggage can I bring?" They create lookalike sites that ask for personal info, payment details, or even trick you into calling fake hotlines.

How to Stay Safe While Searching Travel Info

• Always go directly to the official website: For Cathay Pacific, that’s cathaypacific.com.
• Avoid clicking on ads for baggage allowance: Scammers sometimes buy ad space on search engines.
• Don’t trust “customer service” numbers from unknown sites: These could lead to phone scams.

Bonus Tip: Watch Out for Fake Email Confirmations

Some scammers send fake booking or baggage fee emails claiming to be from Cathay Pacific. If you receive one, don’t click any links — check your official booking account instead.

If you’ve recently received a call or text from 800-925-6278, you’re not alone. Many people look up this number to check if it’s really Walmart — or something more suspicious. Here’s what you need to know.

Yes, 800-925-6278 Is Walmart’s Customer Service Number

Walmart uses this toll-free number for customer support, and in many cases, calls from it are completely legitimate. But here’s the catch — scammers can spoof official numbers to make it look like they’re calling from Walmart, even when they’re not.

How to Tell If It’s a Legit Call or a Scam

• Did you recently contact Walmart? If not, a surprise call is a red flag.
• Are they asking for personal or financial info? Walmart reps don’t usually request sensitive data over the phone.
• Does the caller pressure you? Scammers often try to create urgency — real agents won’t rush you.

What You Should Do

• Hang up and call Walmart directly from their website.
• Never share your Social Security number, banking details, or one-time codes over the phone.
• Use a trusted security app like Trend Micro to scan for scam texts or phishing links.

Scammers Are Getting Smarter — Stay One Step Ahead

Unfortunately, spoofed calls are becoming more common, even using real company numbers. That’s why staying informed is your best defense.
