    Can't find script engine "Jscript" > GXKLoiWHiOpw.js


    This message recently started to pop up.

    Can't find script engine "Jscript" for script C:\users\xxx\appdata\local\temp\GXKLoiWHiOpw.js

    I've tried several suggestions for not being able to find script engine "Jscript" such as

    b. Type cd %windir%\system 32 (Note: there is a space between system and 32) and press enter.
    c. Type regsvr32 vbscript.dll in command prompt and press enter.
    d. Type regsvr32 jscript.dll in command prompt and press enter.
    and

    Dism /Online /Cleanup-Image /RestoreHealth

    and sfc /scannow


    Also a registry script http://www.winhelponline.com/blog/wp...script_fix.zip

    So far the error message has continually popped up while streaming video from Hulu.com, however that's about all I've been doing lately is watching a television show from Hulu using the Firefox that recently while writing this message updated to version 60.0 so perhaps the script error is initiated from firefox?

    I couldn't find any information specifically for a script named GXKLoiWHiOpw.js ... ???

    I found and deleted the file GXLoiWHiOpw.js.

    After a while the error message occurred again and the file must have been copied to the temp folder as now exists after being deleted.

    I'm uncertain what process, app or script is initiating copying GXLoiWHiOpw.js to the temp folder and trying to run Jscript.

    when I type "jscript" from the command prompt I get,

    'jscript' is not recognized as an internal or external command, operable program or batch file.

    This is typical malware behaviour.

    Run a scan with AdwCleaner: https://www.malwarebytes.com/adwcleaner/

    Downloaded and ran Malwarebytes. Will wait and see if it was able to detect and quarantine the offending Malware.

    However it did quarantine some of my data files for a legitimate shareware password program that I purchase over 10 years ago that I've needed to pay $10.00 every so often to keep it up to date.

    I'll need to search through the rest of the quarantined files to make certain it hasn't quarantine other legitimate files needed by applications and/or the OS.

    Malwarebytes seems to have found the malware


    Malwarebytes seems to have resolved the error message problem as I've not yet had another popup error message as noted in the first message.

    FYI,

    I've used Malwarebytes in the past however a few things seemed to have changed.

    There are at least two PC versions of Malwarebytes. There are also other versions such as for Business, etc. some of which are a trail version or need to be purchased.

    The first PC version I installed, scanned and found some malware, quarantined, and also quarantined non malware which I needed to remove from it's quarantine.

    Then it vanished, uninstalling itself from my pc.

    So I downloaded the PC 14 day free trail version which permanently installs itself on to a PC running Windows.

    The 14 day free trial version is a premium version.

    There is a setting under "account details" to either activate license or deactivate the Premium free trail. Also another selection "Upgrade Now"

    The 14 day free trail captures alot more malware than the first version that scans and then uninstalls itself.

    The 14 Day free trail version, after a manual scan all items were selected where I was required to go through the items found and deselected what I thought to be non-malware. Then I manually quarantined the selected items.

    Don't confuse AdwCleaner from Malwarebytes with Malwarebytes itself, the two are quite different. They were at one time quite independent software, but then Malwarebytes bought AdwCleaner. With version 7 they have made the AdwCleaner interface look almost identical to Malwarebytes itself.

    AdwCleaner is not installed on the PC, it is a standalone app that performs an on-demand scan for malware. You can carry it on a usb and scan an infected PC if you wish.

    Malwarebytes requires installing before use. This is because it can, in addition to an on-demand scan, provide real time protection. This is the '14-day free trial' of the Premium version. If you let the free trial lapse without buying or you turn off the trial in 'account details' it then becomes Malwarebytes Free, just an on-demand scanner.

    I've used Malwarebytes in the past however a few things seemed to have changed...
    Since version 3, there is no specific download to install 'Malwarebytes Free' directly as there was for version 2. With version 2 the 14-day free trial was a suggested option that you didn't have to take. If you didn't start the trial the install was Malwarebytes Free from the start. With 3 the trial is non-optional, you have to end it to revert to Malwarebytes Free.

    Yes, looking at it again I think you're correct.

    The first version that temporarily installed has a filename adwcleaner_7.1.1.exe while the second version 14 day free trail has a filename mb3-setup-consumer-3.4.5.2467-1.0.342-1.0.4996.

    So it appears you correct. However the 14 day free trail is a premium version so it appears must draw from a different and larger database as the Adwcleaner found a lot less malware than the Malwarebytes premium version. I didn't count exactly but seem to remember the difference was by several hundred items between items found by Adwcleaner and Malwarebytes 14 day premium version (during the free trial).

    I'm not certain if after the free trail ends with a Free Version still installed if the number of potential malware items will be any different from AdwCleaner and Malwarebytes Premium version. Perhaps one is required to pay for Malwarebytes in order to acheive a more thourogh malware scan?

    You need to check startup prorams in task manager and also shedule tasks as if it runs from a task it may not be picked up its worth opening the script with notepad and see what it does

    With version 3 Malwarebytes Premium claims to provide AV protection in addition to just malware detection, previously in version 2 it just concentrated on malware protection.

    It is interesting to note that when used in an Enterprise environment Window Defender can provide optional malware protection (PUP/PUA). This is not offered for individual use, but it can be enabled in all editions of Windows 10, even for the Home edition.

    Enable or Disable Windows Defender PUA Protection in Windows 10
