His Laptop Was Not Infected. It Had Five Antivirus Programs Fighting Each Other.
A Toshiba laptop was drowning in pop-ups and running slow. A full malware scan found nothing. The cause was years of AVG, Avast, CCleaner, a VPN, toolbars, and update helpers all running at once. Removed with the vendors' own tools plus manual cleanup, startup cleared, Windows Defender left as the only antivirus. A second visit added a WiFi extender for the shop.
“Justin Johnson, Woodstock Computer, is an incredible Christian man, who is so experienced, that he fixed my Wi-Fi problem, Incredibly fast, he charges $100 to totally clean out your computer, he comes to your home and picks up my laptop, and speedily brings it back, I would encourage everyone to call him with computer problems/Wi-Fi issues, he’s also going to make my printer Wi-Fi accessible, incredible!”
— Larry E. · Google review · Read the full storyLarry called about a Toshiba Satellite laptop running Windows 10. Pop-ups kept taking over the screen, the machine had slowed to a crawl, and he wanted it checked for anything harmful and the junk cleared out. On the follow-up visit he also wanted real WiFi out in his shop, where the signal had always been weak or gone.
The scan came back clean
The good news came first. A full check for spyware, viruses, and browser hijackers found nothing. No infection, no hidden miner, no hijacked browser. Larry did not have a virus.
What he had was a pile of programs meant to protect him from one. Over the years the laptop had collected AVG Internet Security, the Avast, AVG, and CCleaner “Secure Browsers”, Avast SecureLine VPN, CCleaner, several update helpers, the Yahoo Toolbar, Windows PC Health Check, and a leftover advertising entry. Every one of them loaded at startup, ran in the background, and nagged him to buy an upgrade. Stack that many on a laptop of this age and you get exactly what he was seeing: constant pop-ups and a machine with no room left to do its own work.
Getting them out
Programs like these are built to resist removal. Uninstall one from the Control Panel and it leaves a browser, a scheduler, and a startup entry behind, and the pop-ups keep coming. So I went at them properly:
- Ran each vendor’s own removal tool, then a manual cleanup to catch the pieces the tools skip.
- Cleared the startup items and background services they left behind, so nothing junk loads when the laptop turns on.
- Pulled the Bing wallpaper and search add-ons that had ridden in alongside them.
- Removed the ScanSnap scanner software, which was throwing a “scanning error” message on its own every few minutes.
- Confirmed Windows Defender, the antivirus built into Windows, was active and protecting the machine. It is all the protection this laptop needs.
The shop WiFi
On the second visit I installed a WiFi range extender for the shop. Placed right, halfway between the router and the dead zone, it gives him a full, steady signal out there instead of a weak or dropped connection.
The result
The laptop is clean, the pop-ups are gone, it starts and runs noticeably lighter, and Defender is on guard. The shop has full coverage. Both visits and the extender fit inside my standard pricing, with the part billed at what it cost me, no markup. Diagnosis is free, and the rates are on the pricing page.
Two things to keep
- Stick with Windows Defender. It is free, built in, and does the job. The third-party antivirus and “PC cleaner” programs are usually the slowdown, not the cure. Please do not reinstall AVG, Avast, or anything like them.
- If you ever want a real speed jump, a solid-state drive is the single best upgrade for a machine this age. No rush. It runs well for what it is.
If your computer is drowning in pop-ups from programs you do not remember installing, book a time online or call or text 770-356-4462. Diagnosis is free, and if there is no virus, that is what you will hear.
Questions people ask
Can antivirus programs make a computer slow?
Yes. Several third-party antivirus and cleaner programs running at once use more of the machine than most infections would. They also generate the upgrade pop-ups people mistake for a virus warning.
Is Windows Defender enough protection?
For a home laptop, yes. It is built into Windows, updates itself, and does not nag or slow the machine. Adding AVG or Avast on top usually makes things worse, not safer.
Why won't AVG or Avast uninstall completely?
They leave browsers, schedulers, and startup entries behind on purpose. The vendors publish dedicated removal tools, and a manual cleanup afterward catches the rest.
