    Dear Malwarefixes,

    I really appreciate your advice.

    I didn’t follow all the steps e.g. Malwarebytes won’t’ run on my old Mac’s system 10.7.5, and the extensions list in Chrome’s Prefs didn’t show Shroomcourt.

    Also, I added a step from PreciseSecurity — open the Applications folder and to delete SoftwareUpdater and Shroomcourt, and it said “Note: Malware may use alternative names instead of Shroomcourt to mislead security programs as well as users. If in case the above list is not present, please look for unfamiliar or suspicious items containing the same extension as update.plist, ltvbit.plist, and download.plist.”

    I added a couple of steps of my own e.g. emptied Trash after moving those files into it from Library, and in Chrome’s Prefs I found I needed to change the old On Startup from Open a specific page.. to Continue where I left off. Also I had to fix Prefs in all three of the browsers on my Mac – Chrome, Firefox and Safari. (Interesting that it had infected Safari, because I hadn’t opened that in weeks, and acquired Shroomcourt only a bit over a week ago).

    But I think I’ve managed to get rid of it. Or at least any sign of it, so far.

    One question – in the Applications folder, the Shroomcourt folder contained just Uninstall and Uninstall_Shroomcourt.txt. Is that what you’d expect? I have NOT run the Uninstaller, and have moved the folder to the Trash, but haven’t emptied Trash yet in case Shroomcourt reappears and I want to give the Uninstaller a go. Is this wise?

    Many thanks

    Stephen, With so many discussions about this adware, we can concur that it is highly dangerous to run any executable file from Shroomcourt and this includes the Uninstall file. Both files you mentioned under Applications/Shroomcourt is anticipated on this type of infection. However, this adware is tricky. It may used other “unknown” folder. Thus, in other machine, Shroomcourt files and folders do not exists. In cases like these, it is still best to run anti-malware scanner. If MBAM is incompatible with your Mac, try Bitdefender Adware Removal Tool for Mac.
