Q: Safari randomly opening new windows

Greetings,

 

I have searched the forum on similar topics, and have tried all the advice I found. However, I have still not solved my problem. I have a MacBook Pro from 2012.

 

My web browser, Safari, keeps opening new browser windows randomly. These include "scam"  webpages for MacKeeper, Media Downloader, Car Insurance, Flash Player and various "warnings" about virus infections. The windows pop up frequently and without warning, even when I am doing something as simple as reading a news website or searching Google. (They are not pop ups that are tied to a specific website.)

 

I couldn't find anything in the Extensions tab in Safari Preferences. I removed various folders from my Library, as directed by other articles, and ran a scan of my laptop using Malwarebytes. (Nothing found.) I ran a scan with Etre Check but it did not reveal any relevant information. The problem still persists.

 

Any thoughts or suggestions would be most welcome. Most of the articles I read on this issues were from 2013 and 2014.

MacBook Pro, OS X Mavericks (10.9.5)

    The code for DNS cache poisoning is often found in URLS sent via spam mails .

     

    DNS cache poisoning has absolutely nothing to do with any URLs sent in e-mails, nor with anything else that the user might do on his or her computer. DNS cache poisoning is a problem on the DNS server itself, and it affects everyone using that server. As such, all of your advice about how to handle a DNS cache poisoning problem is completely wrong. The only way to solve an issue with a poisoned DNS server is to either wait for the owner of the server (typically your internet service provider) to fix the problem or use a different DNS server.

     

    Further, there's no reason to believe that this problem is due to DNS cache poisoning. That is a very unlikely explanation for the problem, and there are many other explanations that are far more likely.

    I haven't had Internet access for several days, hence the late reply. Thomas R., you mentioned about emailing Malwarebytes support with information about my system. I found the email link on the website; but what information specifically does the support team need to determine what's going on? Thanks.

    If you choose Contact Support from the Help menu within the Malwarebytes Anti-Malware app, rather than going to the Malwarebytes website, that will take care of composing a message in Mail with the needed information, which you can review and send.
