Published on:

ZeroAccess is a sophisticated kernel-mode rootkit that is rapidly becoming one of the most widespread threats in the current malware ecosystem. ZeroAccess’ ability to run on both 32-bit and 64-bit versions of Windows, resilient peer-to-peer command and control infrastructure and constant updates to its functionality over time show that ZeroAccess is a modern threat capable of thriving on modern networks and modern Operating Systems.

ZeroAccess remains hidden on an infected machine while downloading more visible components that generate revenue for the botnet owners. Currently the downloaded malware is mostly aimed at sending spam and carrying out click fraud, but previously the botnet has been instructed to download other malware and it is likely that this will be the case again in the future. ZeroAccess should be considered an advanced and dangerous threat that requires a fully featured, multi-layered protection strategy.

ZeroAccess employs mechanisms that are themselves hard to remove such as a kernel-mode rootkit and patched driver files, patched system files such as services.exe and data hidden in NTFS Extended Attributes, removal of NTFS permissions on files used; and because ZeroAccess often employs several autostart points on an infected machine and usually other files that can re-install the malware.

10 Rules to Avoid Online Scams

Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.

  1. Stop and verify before you click, log in, download, or pay.

    warning sign

    Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).

    If you already clicked: close the page, do not enter passwords, and run a malware scan.

  2. Keep your operating system, browser, and apps updated.

    updates guide

    Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.

    If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.

  3. Use layered protection: antivirus plus an ad blocker.

    shield guide

    Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.

    If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.

  4. Install apps, software, and extensions only from official sources.

    install guide

    Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.

    If you already installed something suspicious: uninstall it, restart, and scan again.

  5. Treat links and attachments as untrusted by default.

    cursor sign

    Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.

    If you entered credentials: change the password immediately and enable 2FA.

  6. Shop safely: research the store, then pay with protection.

    trojan horse

    Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.

    If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.

  7. Crypto rule: never pay a “fee” to withdraw or recover money.

    lock sign

    Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.

    If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.

  8. Secure your accounts with unique passwords and 2FA (start with email).

    lock sign

    Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.

    If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.

  9. Back up important files and keep one backup offline.

    backup sign

    Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.

    If you suspect infection: do not connect backup drives until the system is clean.

  10. If you think you are a victim: stop losses, document evidence, and escalate fast.

    warning sign

    Move quickly. Speed matters for disputes, account recovery, and limiting damage.

    • Stop payments and contact: do not send more money or respond to the scammer.
    • Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
    • Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
    • Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
    • Scan your device: remove suspicious apps or extensions, then run a full malware scan.
    • Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
    • Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.

These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.

  1. This tutorial was amazing! I though I had gotten rid of the virus ages ago, but then I realized that it was still there. Thanks for the help!

  2. Thanks for these great instructions! I have used your site previously with great results. I am struggling this time. I cannot get TDSKiller to run. I download it, rename it iexplore.exe. When I run it, the “User Access Control” window comes up and asks if I want to allow it to run, I say yes. Then I get the “hourglass” swirl and nothing happens. I’m running Windows 7 64 bit, SP1. Any help is greatly appreciated.

    • Hello Kristina,
      Can you please go ahead and perform the other steps,then please re-try to scan with TDSSKiller.

  3. I’d like to say that is tremendous advice .It would be Paranoidally Wise also to run Superantispyware, F-Secure’s Easy Clean,
    Comodo’s Cleaning Essentials,Kaspersky’s Security Scan,Norman’s Malware Cleaner ,and Microsoft’s Safety Scanner.

  4. I was infected with some unidentified malware that hijacked my yahoo-webmail and disabled the W7x64-Firewall services (error code 0x80070424).
    To my dismay, Malwarebytes, MS-Security-Essentials, AdvancedSystemCare, CCleaner we NOT able to prevent, identify or remove this infection.

    After reviewing & considering a clutch of other proposed-solutions (complicated, risky, suspect, etc.), I stumbled upon your website.

    So, I thank you so much for your efforts on this most-useful website to counter-attack such malwares.

    Your Step 2 (combofix .exe) was most effective for me and did repair that “error code”.

    If anyone suspects their PC is infected, I recommend they follow all the steps listed here. Worked for me.

  5. Thank you so much Stelian!

    There were so many conflicting guides on the internet saying to do different things but I followed yours from start to finish and my PC seems to be fine now :D

  6. Great site. 1 problem. I have disable Mcaffee but the Combofix continues to show that I have them enabled. Am I safe to run the scan or do you have another option. At this point I cannot afford unpredictable results”.
    Thanks

    • Hello Sigma,
      If you actually disabled the antivirus,firewall and other real-time protection software,than you can go ahead with the scan!

  7. Hello Stelian
    Thank you so much for your help and advice. I have been following the links you gave me to download and cure the problem with no windows update and no firewall after the SMART virus.
    Got to Combofix it found two files for deletion and rebooted, however on starting up I forgot that I have an automatic pop up of ‘Control panel’ that appears. This caused the Combofix to stall, after waiting about 10 mins I turned the computer off and restared with the Malwarebytes Anti-Malware. I have no problem now dowloading new windows updates, so that part seems to have worked. However, the next step would not allow me to complete a full Malware scan, but did let me follow a short scan. Both the Malware and the Hitmanpro did not throw up any more virus programmes.
    I am having trouble with the last part finding the link WINDOWS REPAIR ALL IN ONE DOWNLOAD LINK you recommended – I have found a Tweaking.com – Windows Repair (All in One) v1.9.1 Released 10.22.2012 would this be an updated version and should I download this one?
    Thank you.
    Jan

  8. Thanks to Stelian for another great removal guide.

    I’m not 100 % sure I had ZeroAccess Rootkit on my system. An antivirus program called Stinger identified “FakeAlert!fakealert–REP trojan” but another forum mentioned this is related to ZeroAccess, so I ran Stelian’s Removal Steps just in case.

    The symptoms were rundll32.exe showing in processes, Adobe Flash suddenly installing (even though latest is installed) and some unexpected redirects taking me to (what looked like) legitimate websites.

    Application Data\wcsuie.dll”,DestroyWindow – wcsuie.dll (was identified as malware by Hitman Pro) and there were some hidden entries just called “n” in a hidden RECYCLER directory I’ve never seen before (on XP). I removed all with Hitman Pro.

    ComboFix seemed to hang, even when I renamed it Combo-Fix before downloading it to desktop. Stelian’s guide mentions “report back here” if a problem occurs with ComboFix – So I’ve reported it in this post. I think I’m virus free now, but as ZeroAccess is a particularly persistent rootkit, any expert advice welcomed.

    Kind Regards, NB

    • Hello nbwriter,
      It should be gone from your machine,however if you want to do a double check, you can run a scan with the following tools:
      STEP 1: Run a scan with Eset Online Scanner.

      1. Download ESET Online Scanner utility.
        ESET Online Scanner Download Link (This link will automatically download ESET Online Scanner on your computer.)
      2. Double click on the Eset installer program (esetsmartinstaller_enu.exe).
      3. Check Yes, I accept the Terms of Use
      4. Click the Start button.
      5. Check Scan archives
      6. Push the Start button.
      7. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
      8. When the scan completes, push Finish

      STEP 2: Run a scan with Emsisoft Emergency Kit.

      1. Please download the latest official version of Emsisoft Emergency Kit.
        EMSISOFT EMERGENCY KIT DOWNLOAD LINK (This link will open a download page in a new window from where you can download Emsisoft Emergency Kit)
      2. After the download process will finish , you’ll need to unpack EmsisoftEmergencyKit.zip (Right click on it and select Extract all) and then double click on EmergencyKitScanner.bat
      3. A pop-up will prompt you to update Emsisoft Emergency Kit , please click the “Yes” button.After the Update process has completed , put the mouse cursor over the “Menu” tab on the left and click-on “Scan PC“.
      4. Select “Smart scan” and click-on the below “SCAN” button.When the scan will be completed , you will be presented with a screen showing you the malware infections that Emsisoft Emergency Kit has detected.Make sure that everything is Checked (ticked) and click on the ‘Quarantine selected objects‘ button.

      • Thanks for speedy feedback, Stelian. I’ll run those scans as advised.

        I’m still curious why ComboFix (appeared) to stall. It’s likely the answer is highly technical. What actually happened when I got to Step 2 in your ZeroAccess Removal Guide is ComboFix ran for 30 minutes, then appeared to freeze the machine. I uninstalled ComboFix, updated to latest version, renamed it Combo-Fix and installed the “Console” it requested.

        Some AV Sites suggest stopping ComboFix EX3 processes while its executing will speed it up. Not sure about that… I noted the EX3 process takes up a large amount of RAM while executing. My machine is only fitted with 700MB RAM, I’m wondering (as with many newer programs) if ComboFix simply needed more RAM to execute quickly?

        Kind Regards, NB

  9. You are awesome! To have someone so smart, be so helpful, and for no charge is a blessing. Thank You!

  10. Fantastic! Thanks so much for a thorough and terrifically brutal counterattack on this bug! It saved my friend’s laptop from being flung out of his window!

  13. I’m 30 now and been working on computers for 15 years at least and I’ve discovered some new tools that I haven’t ran before. RogueKiller and TDSSKiller have been added to my arsenal. It’s nice to see that not everyone in the trade hides their techniques. I’m wary when trying new tools but with such a detail write up with responses, I had to give them a shot.

  14. 10/15/2012

    Killer ran fine, but found nothing. Said system was not infected.

    However, I know I have the ZA rootkit. It is running out of the C:\recycler directory.

  15. Un-freaking believable how amazing this is! I have never had my butt kicked by a virus so bad before until now. Followed your steps to the T and no more Zero rootkit. What a life saver you are sir! I had over a terabyte of steam games, pictures,documents etc and was about to throw in the towel until finding your blog! Thanks again for doing what you do.

  17. Thank you, thank you, thank you. I’ve been battling this virus for weeks and your efforts were the only thing that worked for me.

  18. Thanks Stelian,
    I followed your detailed instructions on “Remove System Progressive Protection” Thanks for this. It removed lots of Malware. At the end Rogue Killer had a flashing ZeroAccess image with exclamation mark in the top left hand corner of the screen. It also openned a Firefox webpage with French instructions. I can’t read French so I followed this link. However, TDSSKiller could find no infection. Am I clean?

    Thanks again.

      • Thank you again Stelian!

        That was an excellent reply. I found an additional 12 threats – 4 with Kaspersky and 8 with ESET. I ran Rogue Killer once more: no flahing warning this time, but 1 more threat to kill.

        How do I get reasonable protection. Until very recently I have not had problems with malware, but in the last 3 months I’ve been infected 3 times – this was the worst. I’ve got McAfee Security Scan Plus and McAfee AntiVirus Plus and always have a firewall up, but they seem to be powerless and are deactivated once an infection gets going. I’m never entirelky sure of how an infection get’s in. Windows & always asks if I want to allow software to make changes to my harddrive, but at least once I was tricked – I think it was a bogus Adobe Flash Update. I’m sure on other occasions the infection started via Facebook or just opening a window!

        Thanks again.

  19. exellent webpage! thanks so much! really outstanding. so kind of you to share like this! this is such an enormous help– it’s just wonderful.

    we are now in STEP 6, with the windows repair all in one tool. everything has been perfect up to this point.
    now the instructions above say in #7. Put a checkmark in the following item:
    Repair Temp Files

    REPAIR? repair temp files?

    Now, I am looking at the boxes to check in the tool and the ONLY one that says anything about TEMPORARY FILES is “REMOVE temporary files.” there is not one that says REPAIR temp files, as in the instructions.

    do you mean we should check the box for REMOVE temporary files? or was it meant to REPAIR something else, not the temporary files? i did already check the boxes by the other three choices (Repair Hosts File, Remove Policies Set By Infections, Set Windows Services To Default Startup).

    thank you so much once again. your assistance is just the best.
    kind regards…

    • Hello Stjarn Goss,
      Yes,that was a typo, Remove Temp Files is the the one you need to check. :D

  20. I ran TDSSKiller. It shows win64.Zaccess.a infecting ..\system32\services.exe. It could not remove/repair the infected file. I then tried in safe mode… smae thing.

    Can I go to step 2, then retry step 1? If not, how should I proceed?

    Thanks…
