ErrorSmart – a bogus security tool that should not be trusted
ErrorSmart is not an antispyware software as it says but a smart new scam lurking online for potential victims.
Usually, this fake security tool must be downloaded and installed manually from promotional websites, but sometimes it is distributed by Trojans, software bundles, and sneaky techniques alike.
Error Smart is presented as a reputable security tool, but the facts speak differently: it compromises the system by disabling firewalls and other security applications. It displays large numbers of fabricated security reports that are partially true because the rogue antispyware is able to download additional computer parasites on the infected device. Do not trust this software!
Rogue antispyware software shows predetermined virus scan results to scare you into believing that your device is infected with lots of hazardous malware. In addition, it shows notifications of various imaginary intrusions or cyberattacks. As a solution, such software offers to buy its licensed version to fix all bogus issues.
Please don't believe this scam as there's nothing wrong with your computer apart from ErrorSmart being installed on it. Remove it by scanning your device with a reliable anti-malware tool. Afterward, perform system diagnostics with compatible software to ensure that your device runs smoothly.

How to remove ErrorSmart
Nothing it reports is real.
These steps remove it and undo a payment if you made one.
Step 1: Do not pay, and undo a payment if you made one
ErrorSmart reports problems to sell a licence: the "threats" or "errors" it lists are invented or harmless leftovers. If you already paid, ask your card issuer to dispute the charge and cancel the subscription both in the seller's account and through your bank.
If you called a phone number it showed and let someone connect, treat the PC as remotely accessed and remove the remote tool. Uninstalling it from Windows 11 or Windows 10 does not cancel a subscription by itself.

Step 2: Uninstall ErrorSmart
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10. Sort the list by install date and find ErrorSmart, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).
Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

Step 3: Remove it from startup
Whatever ErrorSmart installed usually starts with Windows. Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.
Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

Step 4: Delete the folders left behind
What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through
%LocalAppData%,%AppData%, %ProgramData% and the two Program Files folders.Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold
.exe,.dll, .js or .ps1 files are the strongest sign.Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 5: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

Protect your privacy - employ a VPN

In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. is one of the leading file recovery solutions you can find on the market - it is likely to restore even lost emails or data located on an external device.
Questions about ErrorSmart
What is ErrorSmart and why is it on my PC?
ErrorSmart is a program that was installed on the PC, most likely together with something else you downloaded. Free software sites and many installers add extra programs on setup pages with pre-ticked boxes, so the extra install looks like your choice even though nobody read the page.
Check the install date in Settings, Apps, Installed apps: the program you installed that day is the probable carrier. If you do not need ErrorSmart, uninstall it. If it belongs to your hardware or to a program you use, search its exact name and publisher first, because drivers and their tools can have unfamiliar names.
ErrorSmart will not uninstall. What can I do?
First restart the PC and try again, because the program may have been running and locked its own files. If the uninstaller is missing or fails, start Windows in Safe Mode, where most third-party programs do not start, and remove ErrorSmart from Installed apps there.
If it still refuses, delete its startup entry and its scheduled task, restart, and try once more. A program that actively prevents removal is behaving like malware, so finish with a Microsoft Defender offline scan. Avoid third-party uninstallers offered on search ads; several of them are unwanted programs themselves.
Should I reset my PC because of ErrorSmart?
Only if the signs point to deeper access. Reset when you see errorSmart in the list of installed apps again after removal, when Windows Security cannot start or update, when remote access tools you did not install keep appearing, or when you simply cannot trust the PC any more.
Otherwise, the plan in this guide plus an offline scan is enough. If you do reset, choose Remove everything and Cloud download for a fresh copy of Windows, restore only documents and photos, and reinstall programs from their official sites. Change important passwords from the clean system afterwards.
Do I need to buy antivirus after removing ErrorSmart?
No. Windows 11 and Windows 10 include Microsoft Defender in Windows Security, which provides real-time protection, scheduled scans, the offline scan and protection against unwanted apps at no cost. Keep it switched on and updated, and turn on Reputation-based protection under App & browser control.
If you prefer a third-party product, buy it from the vendor's own site after reading independent test results, never from a pop-up or a phone call. The lesson of ErrorSmart is that security offers which arrive unasked are the ones to avoid.
ErrorSmart has no uninstaller. How do I get rid of it?
Some scareware does not register an uninstaller, or its uninstaller only opens another sales page. In that case, end the program in Task Manager, then go to Task Manager > Startup apps, right-click its entry and choose Open file location to find its folder. Disable the startup entry, restart in Safe Mode and delete the folder.
Check Task Scheduler for tasks with the same name. Finally, run the Microsoft Defender offline scan, which removes remaining files that Microsoft knows about. Restart afterwards and check that nothing named after ErrorSmart starts again.
I entered my card number in ErrorSmart. What should I do?
Call your card issuer using the number on the back of the card, report the purchase as fraud and ask for a new card. Ask them to block further charges from the same merchant. Watch your statements for small test charges, which often come before larger ones.
If you used a password on the order page or the same e-mail for the purchase, change that password and expect phishing e-mails that mention the purchase. Your bank can also tell you whether the merchant is linked to other fraud reports.
I called the number from ErrorSmart. What now?
End the call and do not let them reconnect. If they installed a remote-access tool, disconnect the PC from the internet and uninstall that tool from Installed apps. Change passwords for e-mail, banking and anything you typed during the call, using another device.
If you paid, contact the bank today for a chargeback. Report the number to the authorities in your country. The program behind errorSmart in the list of installed apps still needs removing: follow the plan in this guide, then run a full scan in Windows Security.
Will the seller of ErrorSmart refund me if I ask?
Sometimes, but do not depend on it and do not let them steer the process. If you contact the seller, do it in writing and keep the replies. Never install software, share your screen or give banking details to get a refund.
The more reliable route is your card issuer or PayPal: a chargeback or dispute for a product sold with false claims. If the seller or anyone claiming to represent them calls you first about a refund, treat it as a scam and hang up.
I let a technician connect to my PC because of ErrorSmart. Is it safe now?
Not until you check. While connected, the caller could install other programs, create a user account or look at saved passwords. Disconnect from the internet, uninstall the remote access program and anything else installed during the call, and run a full scan and the Microsoft Defender offline scan.
From another device, change your e-mail and banking passwords and turn on two-step verification. If the caller opened your online banking, call the bank today. A reset of Windows is the safest option if you cannot tell what was done.
Will Fortect remove ErrorSmart?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For ErrorSmart, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
