Computer Virus Removal Dundee

Your computer is running slowly, pop-ups keep appearing, your browser has been hijacked, or you’ve clicked something you shouldn’t have. Whatever happened, something isn’t right and you’re worried about what’s on your machine and what it might be doing with your data.

Sometimes it’s a genuine infection. Sometimes it’s notification spam pretending to be a virus. Sometimes it’s a scam designed to trick you into paying for a problem that doesn’t exist. We see all three at our Perth Road workshop, and the first job is always figuring out which one you’re dealing with before doing anything else.

We remove viruses, malware, ransomware, spyware, and adware from laptops and desktops. We also clean up the mess left by tech support scams and fake alert schemes. If your computer is acting strange, bring it in and we’ll tell you exactly what’s going on.

Signs Your Computer Is Infected

Slow performance. Your computer used to boot in seconds, now it takes ages. Programs that opened instantly sit there loading. Viruses run in the background consuming processor power, memory, and disk activity while your machine struggles to keep up with normal tasks.

Pop-ups and browser changes. Your homepage has changed to something you didn’t set. Search results redirect to unfamiliar sites. Toolbars you never installed have appeared. Pop-ups appear even when your browser is closed.

Missing files or new programs. Files disappearing is always worrying, especially if it’s followed by a message demanding payment to get them back. Programs appearing that you didn’t install (fake antivirus, system cleaners, cryptocurrency miners) are a clear sign something has got onto your machine.

Unusual network activity. If you’re on a limited data plan and suddenly going over your allowance, malware could be sending your data to whoever created it. Passwords, files, browsing history. Some infections mine cryptocurrency using your hardware, which shows up as high CPU usage and overheating even when you’re not doing anything demanding.

Fake Virus Alerts vs Real Infections

This is the single most common thing we deal with, and most virus removal pages don’t even mention it.

You’re browsing the web and suddenly a full-screen alert appears: “Your computer is infected! Call this number immediately!” or “Windows has detected a critical error!” with flashing warnings and urgent language. It looks terrifying. It looks official. And it’s almost always completely fake.

These are fake virus alerts. They’re either browser pop-ups from dodgy websites or, increasingly, browser notification spam. At some point you visited a site that asked “Allow notifications?” and you clicked Allow. Now that site pushes fake virus warnings to your desktop that look like real Windows alerts.

How to tell the difference:

• Real antivirus warnings come from your antivirus software (Windows Defender, Norton, etc.), not from your browser
• Real warnings never ask you to call a phone number
• Real warnings never demand immediate payment
• If closing the browser makes the alert go away, it was a fake
• If you can’t close it, press Ctrl+Alt+Delete, open Task Manager, and end your browser process

If you’ve got notification spam, we can clear it in minutes. It’s not a virus, it’s just annoying. If you’ve actually called the number or downloaded something they told you to, that’s a different situation and you should bring it in immediately.

Types of Malware We Remove

Viruses and trojans. Viruses spread by attaching to other files. Trojans pretend to be legitimate software but open a back door for other malware once installed. We see plenty of both from folk downloading software from unofficial sources. A common route is cracked software or free download sites offering paid applications for nothing. The “free” version comes bundled with something you definitely didn’t want.

Spyware. Tracks your browsing, records what you type (including passwords), and monitors your activity. The dangerous kind records banking credentials and can access your webcam. If you suspect spyware, change your passwords from a different device until yours is cleaned. Keylogger-style spyware in particular can sit quietly for weeks before you notice anything wrong.

Adware and browser hijackers. Floods you with adverts, redirects your searches, installs toolbars. More annoying than dangerous, but it slows everything down and some adware crosses the line into spyware territory. Browser hijackers are especially irritating because even after you change your homepage back, they reinstall themselves on the next restart unless you remove the underlying program first.

PUPs (potentially unwanted programs). Programs that aren’t technically malware but behave like it. They install themselves alongside legitimate software, collect data, display ads, and are designed to be difficult to remove. We strip these out as part of any cleanup.

Rootkits. These dig deep into the operating system and hide themselves from standard scans. A rootkit can conceal other malware, meaning your antivirus reports a clean machine while infections are still active underneath. Removing them properly requires booting from external media so the rootkit can’t defend itself. This is one case where a professional scan is almost always the right call.

Tech Support Scams

You get a phone call from “Microsoft” or “Windows Technical Support” telling you your computer has a virus and they need remote access to fix it. Or a pop-up appears with a phone number to call for “urgent technical support.”

These are scams. Every single one. Microsoft will never call you about your computer. Neither will any legitimate tech company. These scammers want remote access to your machine so they can install actual malware, steal your data, or charge you for fake repairs.

If you get one of these calls, hang up. If you’ve already given someone remote access, bring your computer to us immediately. We’ll check what they’ve installed, remove anything malicious, change your passwords, and make sure your machine is clean. The sooner we see it after a scam, the less damage can be done.

What a lot of folk dinnae realise is that scammers often install a remote access tool (something like AnyDesk or TeamViewer) and then leave themselves a way back in even after the call ends. They’ll return days or weeks later when you’ve forgotten about it. If you gave anyone remote access and aren’t certain who they were, assume the access is still there and get it checked.

We see this regularly from folk across Dundee, Broughty Ferry, and the surrounding area. It’s not embarrassing and it doesn’t mean you did anything wrong. These scams are designed to be convincing. Just bring it in and we’ll sort it.

DIY vs Professional Removal

You might manage it yourself if: the infection seems minor (computer still works, just slower or showing odd pop-ups), and you’re comfortable running Malwarebytes or similar tools in safe mode. Simple adware and browser hijackers often respond to a good scan.

Bring it to a professional if:

• Your computer won’t start properly or keeps crashing
• You’re getting ransomware messages demanding payment
• You suspect banking or email passwords have been compromised
• You’ve given remote access to someone you now suspect was a scammer
• Your files have been encrypted or are missing
• You’ve already tried removing it yourself and things got worse

We’ve seen computers where someone manually deleted system files they thought were viruses, breaking Windows in the process. Incorrect removal can make things worse. If there’s any doubt, bring it in.

There’s also the question of what you don’t know. A DIY scan might find and remove the obvious infection while missing a secondary payload that was dropped at the same time. Professional tools check places that consumer software doesn’t touch: registry run keys, scheduled tasks, WMI subscriptions, service entries. It takes about ten minutes to run a thorough audit; it can take days to recover from a missed infection that carries on in the background.

Our Removal Process

We don’t just run one scan and hope for the best. Our process uses multiple specialist tools because no single scanner catches everything.

Step one: diagnosis. We boot into safe mode to prevent the infection from interfering with the cleaning process. We identify exactly what’s on your machine: viruses, trojans, spyware, PUPs, browser hijackers, notification spam, or a combination.

Step two: removal. We run multiple professional-grade scanning tools sequentially. Each one catches things the others miss. We also check the hardware (hard drive health, temperatures) to make sure the infection hasn’t been masking a hardware problem underneath.

Step three: verification. After removal, we run a fresh set of scans with different tools to confirm the machine is clean. We check browser settings, startup programs, scheduled tasks, and system services for anything suspicious that survived the cleanup.

Step four: protection. We make sure your antivirus is active, updated, and configured properly. We clear any browser notification permissions that were allowing fake alerts. We check Windows Update is working. Your machine leaves the workshop clean and protected.

Ransomware

Ransomware encrypts your files and demands payment (usually in Bitcoin) to unlock them. It’s the worst type of infection because it directly threatens your data.

Don’t pay. Paying doesn’t guarantee you’ll get your files back. Many ransomware operators take the money and disappear, or come back demanding more. Some provide decryption keys that don’t work.

What we can do depends on the specific ransomware variant. Some older variants have known decryption keys available. For others, we remove the ransomware, assess what’s recoverable, and restore from backups if you have them. If your files are critical and you don’t have backups, we’ll discuss data recovery options honestly, including what’s realistic and what isn’t.

The real protection against ransomware is backups. If your files exist in two places, ransomware becomes an inconvenience rather than a disaster. We can set up a proper backup system as part of any virus removal job.

Preventing Future Infections

Windows Defender is good enough for most people. It comes built into Windows 10 and 11, it’s free, it updates automatically, and it doesn’t slow your computer down the way some commercial antivirus products do. Keep it turned on, keep Windows updated, and you’re covered for the basics.

Most infections come from clicking things you shouldn’t. Suspicious email attachments, fake download buttons on websites, “you’ve won a prize” pop-ups, and links in text messages pretending to be from your bank or Royal Mail. If something feels off, it probably is.

Download software from official sources only. The developer’s own website, the Microsoft Store, or a well-known platform like Steam. Third-party download sites that offer paid software for free are one of the most consistent ways folk end up infected. If you’re nae sure whether a download site is legitimate, gee’z a shout and we’ll point you in the right direction.

Check your browser notification settings. Go to your browser settings and review which sites you’ve allowed to send notifications. Remove any you don’t recognise. This alone stops most fake virus alert pop-ups.

Back up your files. A simple external hard drive running automatic backups means that even if ransomware hits, you’ve got copies of everything. We set up backup systems for folk who want that peace of mind. For more detail, see our computer hardware repair page.
