If you run a business in Austin or anywhere across Central Texas, you have probably seen it happen.
An employee calls in a panic. Their screen is flashing. A warning says their system is infected. There is a loud alert sound. A phone number is displayed telling them to call immediately.
They cannot close the browser window.
Some employees call the number before anyone in IT gets involved.
This is not a rare event. At CTTS, we see it regularly. In fact, we average about one call per week from a business leader dealing with this exact scenario.
Most of the time, the machine is not yet infected.
But it is dangerously close.
This tactic is called malvertising. It is one of the fastest growing entry points for cybercriminals targeting small and mid sized businesses.
What Is Malvertising
Malvertising happens when attackers use online advertising networks to deliver malicious code or deceptive pop ups through legitimate websites.
Your employee could be reading the news, researching a vendor, or even searching Google. A sponsored link or display ad appears. When clicked, it redirects to a fake warning page designed to create urgency and fear.
The goal is simple:
Get the user to download remote access software
Convince them to call a scammer
Steal login credentials
Deploy malware
The ad may appear on a well known site. That is what makes it so effective.
The Real Risk for Austin Businesses
Business owners in Austin, Round Rock, Georgetown, New Braunfels, and Temple often assume their firewall and antivirus are enough.
Here is the hard truth.
Malvertising preys on human behavior, not just technical vulnerabilities.
The risk is not just one infected device. It is:
Stolen Microsoft 365 credentials
Financial fraud through compromised email
Ransomware deployment
Data exfiltration
Operational downtime
In growth focused companies, distraction is expensive. A single compromised workstation can turn into days of recovery.
For professional service firms, manufacturers, construction companies, and nonprofits across Central Texas, trust is everything. A breach erodes that trust quickly.
Why Panic Is the Real Problem
When that pop up appears, the employee is not thinking strategically. They are reacting emotionally.
That is exactly what the attacker wants.
If your team does not have a clear playbook, they improvise.
Improvisation is where breaches happen.
As a Managed IT Services provider in Austin, we coach leadership teams to treat these events as inevitable moments that require preparation, not surprise.
How Managed IT Services Austin Providers Should Address Malvertising
At CTTS, we approach malvertising protection from a business leadership perspective, not just a technical one.
Five CEO Level Best Practices
1. Establish a Clear Employee Response Plan
Every employee should know exactly what to do if a suspicious pop up appears:
Do not call the number
Do not click additional buttons
Disconnect from Wi Fi if instructed
Call internal IT support immediately
Simple, repeatable instructions reduce panic.
2. Implement DNS Filtering and Web Protection
DNS filtering blocks malicious domains before the browser fully loads the page. This stops many malicious redirects at the network level.
Layered protection matters.
3. Deploy Endpoint Detection and Response
Modern endpoint protection looks for suspicious behavior, not just known viruses. This is critical when dealing with obfuscated threats delivered through ads.
4. Use Ad Blocking and Browser Hardening
Properly configured browsers reduce exposure to malicious scripts and ad networks. This is often overlooked in business environments.
5. Conduct Ongoing Security Awareness Training
Annual training is not enough.
Short, recurring training sessions keep threats like malvertising top of mind. When your team has seen the tactic before, they are less likely to fall for it.

Frequently Asked Questions
Is malvertising the same as a virus?
No. Malvertising is a delivery mechanism. It uses ads to redirect users to malicious sites or trick them into installing malware.
Can a firewall alone stop malvertising?
Not always. While firewalls help, layered protection including DNS filtering, endpoint detection, and user training is far more effective.
Why do we see so many fake virus warnings?
Because they work. Fear based pop ups are highly effective at getting users to call scammers or grant remote access. Training and preparation are the best defense.
