Hi,

I have a Mac OS X Yosemite version 10.10.5.  Today, some suspicious pop ups started occurring.  I noticed them when I was shopping on craigslist.  The pop ups would be for similar items from retail stores (ex: searching craigslist music instruments prompted a music instrument retail store pop up.)  I have a couple other pop ups related to out of date flash and something regarding my internet provider.  I haven't had anything like this happen on this computer before.  I ran malwarebytes anti-malware software scan but the issue still remains.

Any help would be appreciated.

Thank you.

Most often all you need to do is empty the caches. Sometimes reinstalling the browser is necessary.

 

Use the FREE CCleaner to clean the computer. CCleaner for Mac - Piriform

Be sure to pay attention while installing and only install CCleaner and not some other toolbar such as Yahoo or Chrome.

For the music store related popup, that could just be a result of cookies.

As to the Flash popup and the ISP popups, can you post screenshots? The ISP one could also be related to cookies. The flash popup could be real or it could just be from a site that gives you fake flash popups to get you to try downloading something on the malicious side.

Do you have Flash installed?

Which browser are you using? Are you using any sort of popup blocking extension? FWIW, Safari has its own built-in popup blocking ability, but it is kind of like a sledge hammer (i.e. it blocks EVERYTHING, even stuff you might want to popup).

Thanks for the advice.  I ran CCleaner and will monitor for the next couple days to see if the popups return.

I don't know if I have Flash installed.  I'm using Chrome for my browser.  I believe chrome has a built in pop up blocker.  That's the only one I believe I'm using.

Install Adblock Plus in Chrome. Once installed click on the ABP icon and choose Filter Preferences.

UNcheck the box next to Allow some non-intrusive advertisements.

You can block the third party cookies...also known as ad and tracking cookies from installing in Chrome. Once

you have blocked their install, run CCleaner to remove the existing ones.
