ESET Online Scanner Frequently Asked Questions

  1. Where can I run ESET Online Scanner?

    Visit the ESET Online Scanner page.
     
  2. How long does it take to run the ESET Online Scanner?

    The ESET Online Scanner will download the latest virus signature database to ensure that threat detection is current. The database should take no more than a couple of minutes to download on a broadband connection.
     
  3. Which web browsers are compatible with the ESET Online Scanner?

    ESET Online Scanner is implemented as an ActiveX control in Internet Explorer 5.0 and later. Compatibility with other browsers (Firefox, Opera, Netscape, etc.) requires the installation of ESET Smart Installer, an application that will install and launch ESET Online Scanner in a new browser window.
     
  4. Do I need administrator privileges when launching ESET Online Scanner under Windows Vista or Windows 7?

    When running ESET Online Scanner under Windows Vista or Windows 7, the ESET Online Scanner automatically switches to administrator privileges when you click Start.

    If the ESET Online Scanner is unable to run using Administrator privileges, uninstall the Online scanner, restart in Safe Mode with Networking and attempt to run the scanner again (view illustrated instructions).
     
  5. Why does the ESET Online Scanner run slowly on my computer?

    If you have other antivirus, antispyware or anti-malware programs running on your computer, they may intercept the scan being performed by the ESET Online Scanner and hinder performance. You may wish to disable the real-time protection components of your other security software before running the ESET Online Scanner. Remember to turn them back on after you are finished.
     
  6. What is the difference between the ESET Online Scanner and other ESET security products?

    The ESET Online Scanner is a program that runs in your web browser and can check for and remove malware. It is not configurable and cannot prevent your computer from being infected by malware. Other ESET security products are anti-malware programs that are highly-configurable, offer multiple layers of protection against malware and can prevent your computer from being infected.
     
  7. How do I uninstall the ESET Online Scanner components from my computer?

    After every scan, an option to uninstall ESET Online Scanner with all its components is provided. Select the check box next to Uninstall application on close to automatically uninstall the scanner once you are done. You can also click Start Control panel Add or Remove Programs select the ESET Online Scanner entry and click Remove. A restart may be required to complete uninstallation.

    Manual Uninstall: Run the ESET Online Scanner Uninstaller (filename: OnlineScannerUninstaller.exe) program, located in the C:/WINDOWS/SYSTEM32 directory on computers running 32-bit (x86) editions of Microsoft Windows and in the C:/WINDOWS/SYSWOW64 directory on computers running 64-bit (x64) editions of Microsoft Windows.
     
  8. Does the ESET Online Scanner include anti-rootkit technology?

    Yes, ESET Online Scanner now includes anti-stealth — ESET's well known anti-rootkit technology also used in other ESET security products. To obtain a full feature 30-day trial version of these products, visit our Free Trial Page.
     
  9. Does the ESET Online Scanner use Live Grid technology?

    No, ESET Live Grid is not included in the Online Scanner.
     
  10. Why are infected files moved to the quarantine after the scan?

    All infiltrations and infected files are moved into the quarantine by default. Files in quarantine no longer represent a threat for your computer because they are reliably isolated from all parts of the operating system. You can choose to either restore selected files or delete the quarantine. 

    Warning:

    Only restore files from quarantine if you are sure that they are not malware or an infected file.

  11. Can I restore files quarantined by the ESET Online Scanner?

    Please visit the following ESET Knowledgebase article for instructions: How do I restore files quarantined by the ESET Online Scanner?

  12. What are the equivalent options in other ESET security products to the ESET Online Scanner?

    The ESET Online Scanner performs scanning as other ESET security products do with the following options: /ADWARE, /AH, /ALL, /ARCH+, /MAILBOX+, /PACK+, /SCANBOOT-, /UNSAFE and /UNWANTED.
     
  13. Does the ESET Online Scanner work with 64-bit versions of Microsoft Windows?

    Yes, the ESET Online Scanner works with x64 (AMD64 and EMT64) versions of Microsoft Windows—it does not work with Itanium (IA64) versions of Microsoft Windows. The ESET Online Scanner is a 32-bit application, which means it must be run in the 32-bit version of Internet Explorer and as an Administrator (see Q7, above). To do so, right-click on the Internet Explorer (32-bit) icon in the Start Menu and select Run as administrator from the context menu.
     
  14. Does the ESET Online Scanner work in Microsoft Windows Server 2003?

    No, currently the ESET Online Scanner does not work with Windows Server 2003.
     
  15. What are Potentially Unwanted Applications?

    Potentially Unwanted Applications are programs that are not necessarily malicious, but may affect the performance, reliability or behavior of your computer. Such applications usually require consent for installation. Often computers will function differently after Potentially Unwanted Applications have been installed. Typical changes include:

    • New windows with advertisements or warning messages which you have not previously seen appear on your computer.

    • New processes are installed and run on your computer—often, they are hidden or masked to prevent casual discovery.

    • The computer responds slowly or displays error messages when performing normal operations that previously worked correctly. This change is often due to increased use of system resources by the Potentially Unwanted Application.

    • Changes in search results

    • You may notice your computer making unusual connections in order to transmit your web-browsing habits or other metadata to remote servers, and to download advertisements and search results based on this information.
    • NOTE:

      Removing Potentially Unwanted Applications may cause other programs that came with them to behave erratically or no longer work.

  16. What are Potentially Unsafe Applications?

    There are many legitimate programs that serve to simplify the administration of networked computers. However, in the wrong hands, they may be misused for malicious purposes. This is why ESET has created this special category. ESET users now have the option to choose whether the antivirus system should or should not detect such threats."Potentially unsafe applications" is the classification used for commercial, legitimate software. This classification includes programs such as remote access tools, password-cracking applications and key-loggers (a program recording each keystroke a user types).

    If you find that there is a potentially unsafe application present and running on your computer (and you did not install it), please consult your network administrator or remove the application.
     
  17. How can I view the log file from ESET Online Scanner?

    The ESET Online Scanner saves a log file after running, which can be examined or sent in to ESET for further analysis. The path to the log file is "C:\Program Files\ESET\EsetOnlineScanner\log.txt" (on 64-bit systems this directory will be "C:\Program Files (x86)\ESET\Esetonlinescanner\log.txt"). You can view this file by navigating to the directory and double-clicking it in Windows Explorer, or by copying and pasting the path specification above (including the quotation marks) into the Start > Run dialog box from the Start Menu on the desktop.
     
  18. Can I select the destination of the scan?

    Yes, the new version of ESET Online Scanner provides an option to select the destination of the scan. This option can be found under Additional Settings.
