    Blockit Ad Remover


    Hi,

    My wife infected her W8.1 machine with Blockit Ad Remover when she opened an infected yahoo.mail. It is a Chrome extension and can be easily removed. But it comes back daily when she uses her yahoo.mail and open her legitimate emails.

    There is no program to uninstall and no program was added recently.
    I went to Chrome privacy settings and cleared all the pop-up and plugin options.

    Scanned with:
    -malwarebites
    -superantispyware
    -spybot
    -emsisoft
    -eset
    -adwcleaner
    -roguekiller
    -ccleaner
    -tdsskiller

    It is still coming back and according to my wife is related to her opening her regular emails.
    I checked her inbox and they all look OK.

    Any suggestions....?

    Thanks,
    -BBDS

    I read the article, did not see anything new there.

    But I read another one - How to protect Chrome Extensions and saw some useful info.

    I enabled Extension Developer mode in Chrome and it gave me the Path and ID.
    The Path was invalid but I was able to find the ID on my "C" Drive and deleted it.
    Because W8 search is not very good I installed "Search Everything" desktop tool to search for that Extension ID.


    So far it looks like the bad Extension is gone from Chrome.


    I will know for sure in a day or two.


    Thanks,

    That's a good thing that everything's clear now.

    You might want to consider installing a security software with real-time protection instead of taking action after getting infected. You can try some of the best like Malwarebytes Anti-Malware Pro, Trend Micro Internet Security or ESET Pro.

    @cipals15 - I use Windows Defender that came pre-installed on my W8.1 machine. I do not want to pay for security, but I scan regularly with free tools I mentioned above. The only tool I ever paid for was Sandboxie and I use it on all my PCs.

    Avast is free. Many people use it.
    There are other good AVs.

    Sure, AVAST, AVG and other free ones are OK, but I think Microsoft Windows Defender or MSE that came pre-installed on my W8.1 machine is sufficient enough. I put my trust not in any single anti-virus program but in multiple stand alone scanning tools. The free tools I use I listed above.

    The extension came back, installed silently in Chrome. All stand alone tools have failed to find the intruder.

    I went to 2 folders -
    c:users/...name.../app data/local/google/chrome/user data/default/extensions
    c:users/...name.../app data/local/google/chrome/user data/default/local storage

    ....and not just deleted the extension id from these folders, but also changed security for these 2 folders - write deny.

    Hopefully this will prevent any further unwanted extension installation, we will see.

    But I have another question - is there any free tool to monitor/expose the process/program that try to access these folders.

    I was trying to use Windows Event Viewer but it did not help, maybe I do not know how to use it for my purpose.

    Thanks,

    Blocking write access on those folders will likely make Chrome just create a new profile.You used some of the best tools out there. Perhaps the problem is that your wife continues to download and install infected software.You could try this:Ensure a Windows PC Never Gets Malware By Whitelisting Applications
