Online Scanner not working
My ESET product detected a threat—what should I do?
Once onto a machine, malware can disable antivirus programs, prevent antimalware programs from downloading updates, or prevent a user from running antivirus scans or installing new antivirus software or malware removal tools. At this point even though you are aware the computer is infected, removal is very difficult.
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.
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.
If no threats are found, you will simply see an information window that no threats were found.
