I get a spam pop-up link 8 out of 10 times I click on something.
Every time I click on something, whether it's the "Questions" tab for my ask.fm or "Images" hyperlink on google, I get some stupid pop-up page. It's those spam links like "PC Cleaner" or "Clean your Mac!" or "Apple Customer Support" with those fake phone numbers and stuff. It's getting EXTREMELY annoying.
I thought it was my computer, so I restarted it. Nope. Thought it was my WiFi. Nope. It happens everywhere else. What in the world is the problem? I haven't had this issue previously, and it started happening about a week ago.
