Ads popping up on facebook and youtube! Help!?

[galoku]

Sounds like malware
Usually on youtube you will have an ad playing before the video starts, which can be blocked using adblock plus

I suggest you do a malware scan with malwarebytes

- get the free program from http://www.malwarebytes.org/
- once downloaded install it
- once installed run it, it may ask for an update. Click yes
- you will have 3 options Preform Quick scan, Perform Full scan and Perform Flash scan
-->Pick Perform Full scan and click Scan
---->This will take a while, depending on the computer specs and how infected the system is.
-When the scan finished it may find infected objects. Click Next if it does and click on Remove selected on the next screen
-Restart the computer and hopefully the popups should be gone

Hope that helps a bit!
