How to Protect Your Business from Phishing Emails

If there’s one scam that keeps catching UK small businesses off guard, it’s phishing emails. These sneaky messages are designed to look genuine - often pretending to be from banks, suppliers, or even colleagues - and they’re getting smarter by the day. One wrong click can expose your passwords, bank details, or customer data.

The good news? You don’t need to be a cybersecurity expert to keep your business safe. With the right mix of awareness, tools, and habits, you can dramatically reduce the risk and keep your inbox - and your business - protected.

Problem / Pain Point

Phishing is one of the biggest cybersecurity threats facing small and medium businesses in the UK. According to government reports, nearly half of all small businesses have experienced some form of phishing attempt in the past year.

The problem is that phishing emails often look convincing. They use familiar logos, professional language, and urgent messages - “Your payment failed” or “Please verify your account now”. It only takes one employee to click a malicious link or download an infected attachment for serious damage to occur.

Common issues that follow a phishing attack include:

  • Compromised email accounts (used to trick customers or suppliers).
  • Loss of sensitive data such as login details or payment information.
  • Business downtime or reputational harm.
  • Costly recovery efforts to clean up and restore systems.

For small businesses without dedicated IT teams, it’s easy to feel exposed. But you can take simple, affordable steps to defend your inbox.

Helpful Information / Solutions

What Exactly Is Phishing?

Phishing is a form of online scam where criminals send emails (or texts) pretending to be trusted sources. Their goal is to trick you into giving away personal information, login credentials, or money. Some phishing messages contain links to fake websites that capture your details. Others attach malware - harmful software that can infect your device.

Step-by-Step: How to Stay Protected

1.       Educate Your Team

Awareness is your first line of defence.

  • Hold short, informal training sessions or share examples of common phishing scams.
  • Teach staff to hover over links before clicking – if the web address looks odd or unfamiliar, don’t open it.
  • Remind everyone: banks and HMRC never ask for passwords or personal details by email.

2.       Use Multi-Factor Authentication (MFA)

MFA adds an extra step when logging in, such as a code sent to your phone. Even if a hacker gets your password, they can’t access your account without that second factor.

  • Enable MFA on all key accounts – Microsoft 365, Google Workspace, and banking apps.
  • It’s quick to set up and makes a massive difference.

3.       Keep Software Up to Date

Cyber attackers often exploit old software.

  • Turn on automatic updates for your operating system, browsers, and antivirus.
  • Use trusted tools that update in the background to save time.

4.       Install Email Filtering and Security Tools

Modern email systems like Microsoft 365 and Google Workspace have built-in spam filters – but you can go further.

  • Add advanced phishing protection or endpoint security tools that block suspicious links and attachments.
  • Consider managed IT support to proactively monitor threats.

5.       Verify Requests Before Acting

If an email asks for payment changes, login credentials, or urgent transfers – pause.

  • Call the person or company directly using a known phone number.
  • Double-check the email address – small differences (like “@paypa1.com” instead of “@paypal.com”) are red flags.

6.       Report and Remove

If you spot a phishing email:

  • Don’t click or reply.
  • Report it to your IT team or forward it to report@phishing.gov.uk (the UK’s National Cyber Security Centre).
  • Delete it from your inbox and trash folder.

Examples / Analogies / Stats

Think of phishing protection like checking ID at the door - you’re verifying that only the right people get in.

For example, one UK retailer received a fake “supplier invoice” email that looked perfectly normal. It came from a near-identical domain name, and an eager accounts assistant paid it. The result? A £2,000 loss. The same scam could have been stopped by a simple phone check or MFA on the email account.

Statistics show phishing remains the most common form of cybercrime, responsible for over 80% of reported security incidents (source: UK government cyber survey). Most victims say the scam emails were convincing, with real company logos and wording that created a sense of urgency.

Benefits (Why It Matters Now)

Phishing attacks are getting more sophisticated, but so are the defenses. By investing just a little time and attention now, you can:

  • Reduce your risk of costly data breaches.
  • Protect customer trust and your business reputation.
  • Avoid downtime caused by recovering from a cyberattack.
  • Empower your staff to spot scams confidently.

Put simply, phishing protection gives you peace of mind. It keeps your inbox safe and your business running smoothly – so you can focus on what you do best.

Actionable Tips (Do-Now Items)

Here’s how to start today:

  1.      Run a quick inbox check – delete suspicious messages and flag anything odd.
  2.      Turn on MFA for all your key accounts.
  3.      Schedule a 15-minute phishing awareness chat with your team.
  4.      Update your devices and browsers to the latest versions.
  5.      Review your email security settings or ask your IT provider to do it for you.

These small actions make a big difference - and they’re all free or low-cost.

Phishing emails aren’t going away, but with the right habits and simple safeguards, you can make your business a hard target. Most attacks rely on human error, not complex hacking – which means awareness and a few smart tools can stop them cold.

If you’ve bought a new laptop or desktop recently, chances are it came with McAfee already installed. It’s one of those “just leave it there” bits of software many businesses never question.

But here’s the honest truth - we often see McAfee causing more frustration than reassurance, especially for small UK businesses trying to keep things running smoothly. So, is it actually doing its job… or quietly slowing everything down?

Let’s break it down in plain English.

The Problem: “It Came With the Computer… So It Must Be Fine, Right?”

Let’s be honest - most business owners don’t actively choose McAfee. It’s typically:

  • Pre-installed on new machines
  • Included as a trial (often 30–90 days)
  • Renewed automatically without much thought

On paper, that sounds convenient. No setup, no decisions, job done.

But in reality, we regularly come across issues like:

  • Sluggish PCs (especially on startup)
  • Pop-ups prompting upgrades or renewals
  • Background scans affecting performance
  • Staff complaining that “the computer is just slow today”

And more often than not, McAfee is part of the picture.

What McAfee Does Well (Fair and Honest)

To give credit where it’s due, McAfee isn’t useless. It does offer:

  • Real-time virus protection – Helps block known threats
  • Web protection tools – Warns about unsafe websites
  • Firewall features – Adds an extra layer of security
  • All-in-one packages – Covers multiple devices in one licence

For home users or very light business use, it can be “good enough.”

But for businesses that rely on speed and consistency? That’s where things start to wobble.

The Reality: Performance Impact and System Slowdowns

What We See in Real Businesses

Across many of the systems we manage, McAfee tends to have a noticeably higher overhead than other antivirus solutions.

In plain terms, that means:

  • It uses more system resources (CPU and memory)
  • It runs frequent background processes
  • It can slow down boot times and general responsiveness

This is especially noticeable on:

  • Older PCs
  • Entry-level laptops
  • Machines running multiple business apps (e.g. accounting software, browsers with lots of tabs)

What Independent Testing Suggests

Independent antivirus testing organisations (like AV-Test and AV-Comparatives) regularly measure performance impact - how much security software slows a system down.

While McAfee often scores well for protection, results over the years have shown:

  • Moderate to high system load during scans
  • Slower file copying and application launching compared to lighter alternatives
  • Background activity affecting performance even when idle

(These findings vary by version and test cycle, but the trend is consistent enough to be worth noting.)

Why This Matters for Small Businesses

A slight slowdown might not sound like a big deal- but across a team, it adds up:

  • 10–15 seconds extra boot time × multiple staff = lost time daily
  • Slower apps = frustration and reduced productivity
  • “Freezing” during scans = disruption mid-task

Over weeks and months, that’s a real cost.

Why McAfee Feels Heavy (In Simple Terms)

McAfee tends to run a lot behind the scenes:

  • Continuous real-time scanning
  • Scheduled full system scans
  • Browser monitoring tools
  • Update services and background checks

Think of it like having a security guard checking every single person multiple times before letting them into the building. Safe? Yes. Efficient? Not always.

Other modern solutions aim to be smarter—checking only what’s necessary, when it’s necessary.

Common Signs McAfee Might Be Slowing You Down

If you’re unsure whether it’s affecting your systems, look out for:

  • PCs taking ages to start up
  • Fans running loudly even with light usage
  • Delays opening files or applications
  • Performance dips at the same time each day (often scheduled scans)
  • Staff regularly restarting machines to “speed things up”

We see these patterns regularly - and removing or replacing McAfee often leads to an immediate improvement.

Alternatives That Are Worth a Look

Without pushing any one vendor, there are lighter, business-friendly options available that tend to offer:

  • Lower system impact
  • Quieter operation (fewer pop-ups)
  • Central management for multiple devices
  • Better performance on older hardware

Even built-in tools like Microsoft Defender (included with Windows) have improved massively and are now a solid baseline for many small businesses.

The key is choosing something right-sized for your setup—not just sticking with what came in the box.

Benefits of Reviewing Your Antivirus Setup Now

Switching or reviewing your current setup can bring some quick wins:

  • Faster PCs – noticeable improvement straight away
  • Happier staff – fewer complaints about slow machines
  • Better value – avoid paying for something that isn’t ideal
  • Stronger security posture – when properly configured

It’s one of those small changes that can make a big day-to-day difference.

Actionable Tips: What You Can Do Today

1. Check What You’re Running

  • Go to your installed programs
  • Look for McAfee subscriptions or trials
  • Check expiry dates—you might be paying without realising

2. Monitor Performance

  • Open Task Manager (Ctrl + Shift + Esc)
  • Look for high CPU or memory usage linked to McAfee processes

3. Review Startup Impact

  • Check how long your PC takes to boot
  • Compare before and after disabling startup items (carefully)

4. Don’t Run Multiple Antivirus Tools

  • This can actually slow things down further and cause conflicts

5. Get a Second Opinion

  • A quick IT health check can confirm whether McAfee is helping or hindering

McAfee isn’t “bad”—but for many small businesses, it’s simply not the best fit. The biggest issue we see is its high system overhead, which can quietly drag down performance over time.

If your team is dealing with slow machines, it’s absolutely worth reviewing what’s running in the background—especially if it came pre-installed.
