Virus on Safari

First RELAX...there are no Mac virus'.

With Safari running, click the Safari menu item in the upper left, select block pop up windows.

Also, get rid of any "mac trojan detecting devices" you have installed. They are junk and may very well be malware themselves.

i visit a page there are some words that are underlined and when you hover over them an add pops up. Also on the facebook pages of users with timelines there are ads that can't be removed that pop up saying things like "find singles near you" and such, but most of the time the ad doesn't load. Also whenever there's a search box on a website, as i type in my search a search engine appears that remembers all the searches i've made on every website.

that seems like normal internet behavior to me. You are fine.

Seems to me that there is a settings link on Google where you can turn somemof those things off. I'm on my iPad right now and iOS is different so I can't test it to be sure. Try going to google and see if you can change some of that.

Try resetting Safari to it's default settings.

One key to your answer lies in the image you posted: "Text Enhance".

Enter those two words into your favorite search engine and you'll see dozens of related discussions about how to block or disable at least some of the pop-up content coming from related websites.

This article on a competing website is Windows Internet Explorer-specific, but specifically names three of the sites responsible for some of that annoying pop-up content:

us.intellitxt.com

vibrantmedia.com

cdn.optmd.com

I've entered those web addresses (and may others) into my wireless router's 'website filter' to prevent those specific sites from displaying content.

Safari 5.0.5 offers an add-on extension that might help too: AdBlockPlus, but because I block at the router level, I haven't tested it.

TextEnhance is a particularly irksome variety of malware called "adware".

Get rid of it by going to Safari Preferences and selecting the Extensions pane. Look for something called "M-Codec" or "Codec-M".

Delete it.

It is not a virus. It is malware that you installed by providing an administrator name and password.

Next time you are presented with a dialog box asking you if you want to install a toolbar, search optimizer, virus scanner, app cleaner, or anything along those lines treat it the same as you would spam. Ignore it.

Thank you so much for this advice. I had the same problem and just got rid of it. I definitely need to be more vigilent next time.

THANK YOU! Been bugging me for ages as well, I had no idea it was so simple.

I have exactly the same problem but on Firefox not safari. On Firefox there is no extensions option and I have done a search for M-Codec and Codec-M to no avail. Any suggestions? Thanks

Welcome to Apple Support Communities. We're all users here.

I won't guarantee that it will solve your problem, but Firefox Version 20 (I'm running OS X 10.6.8) does have Extensions.

Firefox, Tools, Add-ons Manager, and choose the Extensions tab

The Adblock Plus extension (free) might also help.
