Protect your PC from malware

Are your Google search results being redirected to annoying ad sites?

Did you know there are plenty of free software programs that will identify and remove malware hiding in Microsoft Windows?

Google’s Chrome browser has been seeing issues with ‘chrome-navigation-error.inof redirect’.  It is suspected of being botnet related.

I use the Firefox web browser with Adblock, and I run AVG anti-virus. Frequently, but not always, when I click on a link in a Google search result, it takes me to a page advertising something instead of going to the page indicated. If I go back to the search results and click the same link, it usually goes to the correct site. I thought this might be malware, but I have scanned with AVG and Malwarebytes, including anti-rootkit, and there is no indication of anything wrong. Researching the problem, I came across concerns that the Chrome browser could have this behaviour, and the suggestion was to disable extensions. I’m not very happy to do this because my various Firefox extensions add functionality I value. Geoff from Google

Apple Mac OS X and Linus users are also seeing this, although, no Firefox users have reported the issue.
When there is malware on your computer, the best way to take care of the situation is to identify it.

Malware is dangerous to your computer because an attacker can use a small security hole to install more malicious software.

Before trying to get rid of malware, make sure you have all your programs and data backed up.

Malware Removal

  1. Run Malwarebytes Anti-Malware in Safe Mode for faster removal of malware.
  2. Reboot your PC and keep pressing F8 before Windows loads.
  3. When in the Boot Menu, run Malwarebytes again
  4. Keep rebooting and re-running Malwarebytes until there are no longer issues
Using Microsoft’s SmartScreen filter is helpful in keeping your system protected.  The SmartScreen filter creates an SHA-256 hash of executable code and sends it to a Microsoft server.

The bad code or websites is blocked and a message saying “Windows protected your PC,” will appear.
Most malware usually targets the ‘low hanging fruit’ that hundreds of millions of users who never install patches.  Also users who run pirated copies of software with a built-in back door are attacked.
