22 Nov Safari Trojan Horse Virus Warning

Posted at 14:10h in Cyber Security, Support by
Is your Safari internet browser stuck at Trojan Horse Virus Warnings.

The Problem

“I have clicked on a link and been redirected to a page that is telling me I have a Virus or a Trojan Horse and it is asking me to call a number to release me”

The Solution

There are some very unfriendly webpages out there and if you are unlucky to come across a message like one of these it can be pretty tricky to get yourself out of the loop you are stuck in. Pages like this are commonly known as RansomWare and you have probably arrived at this point because you navigated to a maliciously-crafted web site or link. Either way you are stuck and don’t appear to have a way out.

The text of the message reads like this (or similar)

So how do we get away from here?
We have come across this issue on numerous occasions and this is how we have successfully dealt with the problem.
Firstly, have a look at the address bar in Safari and make a note of the actual page you are stuck on, this will be useful later.
Now, press the following key combination cmd-W. The cmd key is next to your space bar. This should close the window that you are stuck in. Regardless of wether this closes the window or not now go to the Menu in the top left hand corner and select Force Quit… A small window will appear. Highlight the Safari Application and select the Force Quit button. This should close Safari.
At this point we recommend you save any unsaved documents you have open, quit all open applications and restart your Mac.
Once the Mac has restarted re-open Safari.
  • If it asks if you want to open the page that you were on when you force quitted then say no.
  • If it just goes back to the same page then cmd-W immediately.
    • This should leave you in the above state where the Safari application is open (ie: next to the  Menu it says Safari) but there are no actual windows open.
     
    Now go to Safari menu, Preferences… and select the Privacy Tab

    Next, click the Details… button and you will get to this point.

    You can either find the stored data file that refers to the actual page you were stuck on by using the search box, or simply Remove All

    If you choose the quick way, Remove All you will find that any previously visited websites that you have told to remember your sign in details may need to be signed into again but you will definitely get rid of the bad site in the process.
