Finally an ad-blocker for Facebook which is working. It was so annoying every 2 posts to see ads (one "Sponsored" and one "For You") which i was spending a lot of time to block all those irrelevant ads. 

I don't like Ads and i don't care if they are relevant or not. I don't want any ad on my screen.

But i was one step before to stop using Facebook because of the ads, and i tried to find any ad-blocker that it will work.

After trying many ad-blockers, i was surprised when i found a small extension for chrome with bad reviews (probably fake) to work perfect.

And i am able again to start scrolling the Facebook feed without the annoying ads.

Perhaps there are more ad-blockers which i haven't tried them yet but here is the link if anyone wants to install the same ad-blocker for facebook:

First of all, you must learn what you see is a virus and what not.

If you see many tagged names or titles like "Watch this video" is a virus. That's sure 100%.

It's better to miss something from your friends and not see it, instead of get a virus!!!

Let's take step-by-step what you have to do.

1. Change your password.
2. Go to your Settings --> Security and press the edit on "Where You're Logged in" After press "End activity in all the devices". You can reconnect later.
3. Go to https://www.facebook.com/bookmarks/pages and check if it has been created any page. If has created pages by stupid names like "igarzduia" or "5896CGF" and others like that, follow the step 4, otherwise go to step 5.
4. To remove the pages you have to get inside these pages. If you press on the title on the page on https://www.facebook.com/bookmarks/pages, it will show you to create a page with this name (but also it has been created) so press "Skip" again and again until you get inside the page. Then go to the settings --> Remove page. Follow this step for all your pages that have been created by the virus.
5. Go to your profile, find the virus (videos or whatever else is the virus) and press the arrow next to the post and delete it. If the virus is from other person that has been tagged you, go to the arrow on the post and press "remove the tag".
6. Log out and reconnect. 
7. Scan the computer with AVG or other Antivirus you have.
8. And you are ready!
