Q: Redirected to a **** site

If you were using Safari, force quit Safari and restart it holding the shift key.  This will usually work but some of the redirects cannot be eliminated.

Ciao.

If your browser of choice is Safari, there are a few things you can do regarding Extensions

and/or other items such as adware. Your surfing may have acquired some unwanted bits

that make or enable the redirect to occur...  You can turn off Safari Extensions in browser

preferences, as well as choose to add or remove new ones. I have none running in Safari.

{There isn't a virus involved in the browser activity you've experienced. No antivirus could

solve a problem when the answer is another direction. The worse, is usually an adware.

A few malware-like items can be a pest. The false ransomware scam is troublesome.}

• If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support

See how to close the browser & start up without it automatically re-opening the page again,

as part of this Support page overview:

• Stop pop-up ads in Safari - Apple Support

There are several details in the above Support page that are worth a try. And there used

to be more until that page was modified recently; it is not as helpful overall and better info

is now missing. Seems like two topics were rolled into one, with best parts removed.

Since you appear to be using El Capitan 10.11, if you have some issues in Safari loaded

om the previously visited site, the OS X will attempt to remove adware by itself... on restart.

But note the Safari versions cited in the above Support links, & actions to try based on that.

Several Apple support web pages have been changed, so links within them aren't what

they used to be; some pages they had a few months ago linked within, go elsewhere now.

If there is an adware or other problem, you could try some manual methods to isolate and

remove the problem; there are a few free apps that could help handle adware. Anyway...

I spent additional time before posting this reading through several bookmarked places that

had more information to resolve issues in earlier OS X versions, they've been changed now

the main OS X in use is supposed to be El Capitan. My newest OS X is Mavericks 10.9.5

so I have other methods I'd use in most older OS X versions for issues, to solve them.

Hopefully the two links will be of some usefulness. There are other sources of info on how

to deal with browser redirects that are more difficult than you describe. I seldom use any

because I am careful when browsing...

You may be able to see some items that could affect your computer if you were to use

Etrecheck to generate a report and post that in a reply to your thread. Others who read

it may see something that indicates an issue; sometimes an issue is not what you think.

http://etrecheck.com/#about another (free) helps remove adware http://adwaremedic.com/

Both of these ^ items were developed by contributors to these ASC discussions & work.

There are manual methods of discovering information inside the OS X and also how to

find & remove bad bits from system; there is a learning curve, and worth the time. Avoid

mackeeper, cleanmymac, & other retail questionable products that can break your files.

In any event...

Good luck & happy computing!

First, never use any kind of "anti-virus" or "anti-malware" software on a Mac. That's how you cause problems, not how you solve them.

You weren't infected with anything. You could be infected by downloading and running unknown software that you don't need, just because something or someone on a web page prompted you to.
