    I have also continued to redirected to Web sites at random.  I ran Spybot, Ad-Aware and Malwarebytes, scans were clean.  I keep getting redirected to a site that says I have registry problems and to perform an audit. Have not yet done.

    Thank you.  I have McAfee and MS Security Essentials.

    Can you tell me how can I get rid of internet redirect me to malicious sites?

     
    If you have both installed and executed they WILL conflict. -uninstall one or the other, or at least turn it off
    Download and install Malwarebytes Anti-Malware - update and run a scan complete delete everything it finds.
    Check your Hosts file and verify that you do not use an unknown proxy server.
    If you need more - you would be better at a site specialized in malware.
    www.bleepingcomputer.com and www.aumha.net are two of the better ones.

  • Windows Defender will not be updated

    I am experiencing strange shift of internet and I think it's because Windows Defender won't be able to update. I am running Vista x 64 final. I recently started to receive a new error every time I start my computer, something to the effect of Windows Defender service is unable to start. If I try to start it manually, I got the error: 0 x 80070003: the system cannot find the path specified.

    Normally I wouldn't complain about windows Defender does not because I have my own solutions, but I believe that it is still problematic within my system. Every half hour or so, my firewall warns me to say that something in a temporary folder called mpistub.exe or something is trying to access the internet. I found this exe is a windows update, so I allow it through. Now, I believe that because the service cannot start, the update is impossible to apply and continues to go to the internet to try to get a shift to internet update, causing news for my pc everything.

    Someone knows something like that? I would like to reinstall windows Defender so that it can update itself and let my only internet. And I don't mean simply turning on or off; I can't do this if the service does not start. Oh and I tried to restore to an earlier date, it is not far enough.

  • Windows Defender does not work with Microsoft Security Essentials

    I just want to confirm I'm sure I see Windows Defender listed on the site alongside the Microsoft Security Essentials in a list of items to choose from - if we choose security while we can not run the Defender is that correct? Vista runs on this toshiba that has been in place. Windows Defender is not running but essentials runs with full daily verified updates scans and other readers of both records - the concern, it is that be enough security we should do other things regarding the last blackened on computers, we have seen happening with friends and the fake software updates We have seen with the neighbors not accepting real software, they thought were updated - but in the end a fake. They were running microsoft security databases, but didn't yet these things happen - no pleasure with the laptop still being down in a different place/city. Any info would be nice to hear, clear terms, just trying to help people close to home and at a distance from time to time thanks Jen

    I'll simplify the answer...

    1 Microsoft Security Essentials has his own Defender. Running 2 defenders only create conflicts.  MSE will stop Windows Defender.

    2. no security program is sufficient for protection. Be careful, to surfing and what to download.

    3. you can install "we demand" programs such as Spybot Search Destry and Malwarebytes. They do not run until you 'open '.
    I have Avast Home Edition for "real-time" protection, and I have Spybot Search and Destroy more Malwarebytes.

  • Windows Defender does not illuminate. Said he did not need with MS security essential

    Asked to click on the link to activate MS Windows Defender. By clicking on the link does nothing. It told me that Windows Defender is not necessary when MS Security Essentials is installed and has probably been disabled. Should I remove Windows Defender and use only Security Essentials. Is this correct?

    Hello:

    It is true that you no longer need Windows Defender after installing MSE.

    However, you do not have to uninstall it. It has in fact been disabled. You can delete all of your shortcuts, if you wish.

    Is no longer, you try to run Windows Defender, that's why I recommend you delete your desktop shortcuts and or the menu of the program. Just pretend it isn't there. This isn't hurt anything by remaining installed.
