What are Potentially Unwanted Applications?
Potentially unwanted applications are not necessarily intended to be malicious, but they may affect the performance of your computer in a certain way. Such applications usually require consent for installation. If they are present on your computer, your system behaves differently (when compared to the state before their installation). The most significant changes are:
- new windows you haven’t seen previously are opened
- activation and running of hidden processes
- increased usage of system resources
- changes in search results
- application communicates with remote servers
What are Potentially Unsafe Applications?
There are many legitimate programs which 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. Our clients 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 keyloggers (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.
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\EsetOnlineScanner\log.txt". You can view this file by navigating to the directory and double-clicking on 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.
Can I select the destination of the scan?
Yes, the new version of ESET Online Scanner provides an option, where you can set the destination of the scan. The option can be found under Additional Settings.
ESET Online Scanner is unable to run even when using Administrator privileges.
It is possible, that a third-party security software prevents ESET Online Scanner from running by setting up a so-called “killbit”. To avoid this problem you have to use regedit.exe, where you under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{7530BFB8-7293-4D34-9923-61A11451AFC5}
delete the value "Compatibility Flags" REG_DWORD 0x00000400.
