What RegGenie does on an infected PC

From our report of Dec 2017 · not reviewed since

RegGenie is a bogus PC optimization software that might be installed without your knowledge

RegGenie is a potentially unwanted program (PUP) that is presented as a registry cleaner and PC optimization tool.

On the official website, it offers to optimize computer's screen and fix computer errors. However, security experts warn about its questionable functionality.

The so-called RegGenie virus might infiltrate the system in a software bundle. As soon as it gets inside, it typically modifies the system and starts showing ads.

Therefore, RegGenie works as a scareware that wants to trick users into buying the paid version of the program by showing fake scan results. However, we can assure that this tool is not worth spending any cent.

After testing RegGenie on our computers, we discovered that this program detects unimportant registry errors that can hardly help people to make their machines run faster. Of course, after "scanning" computer, this program reports about a long list of PC-related issues that can be only fixed after purchasing the license.

No matter how trustworthy RegGenie ads look, beware that they are set only to push the user into purchasing the fake licensed version of this questionable program. Please, do NOT do that because this is a straight way to identity theft and similar issues that can be initiated after revealing credit card information, full name, and other sensitive data.

Additionally, RegGenie malware is reported of triggering redirects to promotional websites and displaying ads on each website user visits. What is more, instead of improving computer's performance, it may even slow down its work.

Therefore, you should not keep this program installed on your PC. If it has started showing you misleading pop-up warnings that are reporting about tens of different issues, you should remove RegGenie with the help of or another anti-malware.

All major security programs identify this cyber under the name of PUA.RegGenie. Thus, you shouldn't encounter any difficulties with automatic RegGenie removal.

Questionable PC optimization program might be installed without your permission

Nevertheless, the program has an official website RegGenie.com and is available on various free file-sharing sites; it still might end up on the computers without user's knowledge.

RegGenie is mostly spread on the Internet just like any other potentially unwanted program. If you want to avoid it, try to ignore these advertisements that offer checking computers for free. Typically, once you click on such alert, you can easily agree to download the trial version of PC optimization software.

However, this program might also be promoted in software packages, so it might sneak inside the system during the installation of freeware or shareware. Security researchers from No Virus report that majority of computer users fail with installation and unintentionally download PUPs.

To avoid installation of questionable security or computer repair programs, you should use Advanced/Custom instead of Quick/Recommended settings and remove ticks for all pre-selected third-party applications.

How to remove RegGenie

A loader's job is to install other malware, so treat the PC as infected with more than one program until the scans are clean.

  1. Step 1: Delete scheduled tasks that bring it back

    Open Task Scheduler from the Start menu and click Task Scheduler Library. Select each task you do not recognise and read the Actions tab:

    • a task that starts a file in %AppData% or %Temp%
    • runs powershell with a long encoded line
    • opens a web address belongs to RegGenie or a similar program

    Right-click such a task and choose Delete, and check the subfolders too. Leave tasks from Microsoft, your PC's maker and programs you use. Task Scheduler is the same in Windows 11 and Windows 10.

  2. Step 2: Remove it from startup

    Whatever RegGenie 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.

  3. Step 3: 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.

  4. Step 4: 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.

  5. Step 5: Change passwords from another device and sign out other sessions

    Assume that the passwords saved in this PC's browsers, and the accounts that were open in them, are known to the attacker. From a phone or a clean computer, change the e-mail password first, then banking, shopping, social and gaming accounts.

    Use each service's option to sign out of all other sessions, because stolen cookies keep a session open even after a password change. Turn on two-step verification on each account. Wait with the infected Windows 11 or Windows 10 PC until the scans are clean.

Uninstall RegGenie from the computer

If you want to remove RegGenie from your computer, you should waste no time and follow these steps:

If these instructions failed to help you to get rid of this program and haven't eliminated its annoying alerts from your browsing routine, you should think about automatic RegGenie removal.

  • Click Start -> Control Panel -> Programs (or Add/Remove Programs) -> Uninstall a Program.
  • Here, look for RegGenie and other unknown entries, and select "Uninstall."
  • Click OK to save the changes.

After removal: passwords, accounts and prevention

Accounts come next

Because the PC showed regGenie in the list of installed apps, a sign of a program that could read browser data, the clean-up is only half of the work.

The other half happens in your online accounts.

Change passwords from a clean device, beginning with e-mail; sign out of all sessions; check forwarding rules and recovery phone numbers; and turn on two-step verification with an authenticator app or a passkey. Ask your bank to replace cards saved in the browser.

Why the order matters and what to check in each account: secure your accounts after malware.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files.

More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.

Questions about RegGenie

Can I safely uninstall RegGenie?

If you did not install RegGenie yourself and it is not part of your hardware or a program you rely on, yes. Uninstalling an unwanted program does not harm Windows. Before you do, search the exact name and publisher to be sure it is not a driver tool, a printer utility or a game launcher with an odd name.

Then remove it from Settings, Apps, Installed apps. Ignore any offers or warnings in its uninstaller about losing protection or performance. Afterwards check Startup apps and your browsers for leftovers, and restart once to confirm that it does not reinstall itself.

RegGenie 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 RegGenie 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.

Why didn't my antivirus stop RegGenie?

New trojan builds are packed and changed often so that signatures do not match, and some are signed with stolen or bought certificates. Many arrive inside password-protected archives, which scanners cannot open until you extract them.

Some downloads also tell the user to turn off the antivirus "because it gives false alarms", a common line in cracked software instructions. Keep real-time protection on, never disable it for an installer, and run the offline scan whenever you suspect something slipped through.

What are the signs of a trojan infection?

Most trojans try to leave no visible signs, so look for side effects. Common ones:

  • Windows Security turned off or unable to update
  • new entries in Startup apps or Task Scheduler
  • programs in Installed apps you did not install
  • browser settings that changed by themselves
  • unusual network activity while the PC is idle
  • password-reset or login-alert e-mails you did not trigger

None of these proves an infection on its own. Together with an antivirus alert naming RegGenie, they are a strong reason to follow the full plan.

Is it safe to do online banking after seeing regGenie in the list of installed apps?

Not on that PC until it is clean. A program that produces regGenie in the list of installed apps runs with your rights and could read what you type or what the browser shows. Use a phone or another computer for banking and for changing passwords.

When the offline scan of the affected PC is clean and nothing suspicious starts with Windows any more, you can go back to using it. Check your bank statements for the past weeks either way, and call the bank if anything looks unfamiliar; banks can block cards and reset access quickly.

Can a normal remote support program be a backdoor?

Yes. Tools such as AnyDesk, TeamViewer and ScreenConnect are legitimate, but whoever controls the account behind them controls the PC. Scammers install them during fake support calls, and some trojan campaigns install them silently because antivirus programs do not flag a genuine, signed product.

If you find one you did not set up, uninstall it, check Startup apps for related entries and change passwords from another device. If money or accounts were involved, call your bank and report the incident.

Should I reset my PC because of RegGenie?

Only if the signs point to deeper access. Reset when you see regGenie 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.

Why can't I find RegGenie in antivirus databases?

Because it is new or because it is listed under a different name. Antivirus companies name threats after the family they belong to, and a program that appears as RegGenie on your PC may carry a generic or unrelated label in their databases.

Many new samples are first detected only by behaviour, without a family name. What you saw, regGenie in the list of installed apps, is enough to act on:

  • end the program
  • remove its startup entry
  • run a Microsoft Defender offline scan
  • secure your accounts

A detection name from a scan is worth noting for later.

Can RegGenie spread to other devices on my network?

Most trojans aimed at home users stay on the PC they infected, but an attacker with remote access can look at the network, open shared folders and try passwords on other devices. Loaders sometimes deliver worms or ransomware that do spread.

Disconnect the PC while cleaning, run a full scan on other Windows PCs, change the router's admin password and the Wi-Fi password if they were saved on the infected PC, and update the router's firmware. If other PCs show the same detection, treat them as infected too.

Will Fortect remove RegGenie?

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 RegGenie, 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.
