Does my computer have a virus?

[Lea]

Yesterday I started noticing that my internet was acting weird. Whenever I search for something or pull up facebook or Twitter there are all these ads that aren't normally there. I know sometimes there will be ads on the side but these are at the top of the page and make the content I'm actaully looking for towards the bottom. And it keeps asking me if I want to display secure content. It's never done this bfore. It also says ads not by this site so I don't know why they are showing up now.

Facebook specifically has a new look, so this isn't a problem with them. I really don't think you have a virus and you can set up facebook to be secure. If you are concerned about a viris, run an antivirus scal when you are off of the internet, Load up Microsoft Essentials and you will be protected.

Try this:

Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter. You will now see some drivers being loaded. There will be a pause at some point. This usually lasts for no more than 30 seconds.

If that's successful, download and run TDSSKiller.exe from Kaspersky Lab. It's tiny, and takes just a minute to run. It hunts down and kills a specific family of rootkits:

Regardless of the results, download the free version of Malwarebytes' Anti-Malware (MBAM). Install it, get updates and run a full scan (still in Safe Mode). This is a direct download link. Copy and paste it into your browser’s address bar, and press Enter.

After that, boot normally and run another full scan with MBAM. It will detect any malware that wasn’t running in Safe Mode.

If the problem still exists, download and run the free Kaspersky Virus Removal Tool:

You should now delete TDSSKiller.exe and the Kaspersky Virus Removal Tool, as updated versions are often made available. Malwarebytes' Anti-Malware can be easily uninstalled, should you wish to do so, but it may prove to be beneficial in the future.

Hope this helps.

what you are suffering from is a type of malware known as "adware" that injects adverts into web pages that you visit.

To get rid of it, first try opening the browsers extensions management page, and remove any dodgy extensions that have been installed, that should fix the problem.

If that doenst work, next thing to try is to run a scan with some antimalware software such as Malwarebytes Antimalware or SuperAntiSpyware, if one of those doesnt find and fix the problem, try the other one.

Once you have got rid of the malware, i strongly recommend installing the "FB Purity" extension as it hides the facebook's own built in sponsored ads and sponsored stories in the newsfeed, and gives you lots of other junk cleaning and customisation options on facebook: http://fbpurity.com
