How do I remove "Offers4U"?

You unfortunately have adware/malware installed on your system. You can remove it one of two ways; manually or with Malwarebytes. Malwarebytes is a malware-removal program designed by a very respected poster, and as I've used it on my own computer, I can vouch for its safety and ease. It will NOT install malware on your computer, so please, don't believe the opposite if you hear it. I would suggest going the Malwarebytes route because it's far simpler.

Wow! Excellent information! Thank you

You're welcome! I'm glad I was able to help. 🙂

I must admit I was skeptical of downloading another unknown to me piece of software but I did and so far, so good. It removed the adware. Thanks. I'll update with any other results if necessary.

Thanks!

I too have been having frustrating problems with offers4u and Deal Top, both of which only seem to have attached themselves to eBay.

I have Malewarebytes installed and ran it yesterday at least 5 times although at least 3 of those produced no results.

I also have my system geared up to block pop-ups.

THREE phone calls with Apple Support resulted in me binning various cache folders and ultimately re-installing the OS.

My iMac is just 2 months old and runs on the latest El Capitan system 10.11.5 and seems to have had it's share of teething problems (e.g.frozen screen) but then I don't always do things right being only a 2 month old MacHead!

And my adware/maleware problem was probably caused by my own idiocy when I fell for downloading Mackeeper which I've since discovered should be kept at the length of a barge pole!! I stick my hand up and say I own up to my mistake but it's a bit of a shame that the bods actually selling Apple products don't give out general warnings of certain nasty programs. But we live and learn!

I have yet to check out eBay to see if re-installing the OS and then letting the iMac run for over 30 minutes in safe mode has solved my problem. I was told yesterday by Apple support that the safe mode would knock off the remaining temp files and caches and would also reset something called envy run.

I read on a Mac forum this morning he didn't think Safari would be affected, but my pop-ups showed up on both Safari and Chrome.

One of my daughters uses Firefox with a special add-on which I might consider using.

And eBay seems to be clean of the pop-ups when I log in via Safari on my iPad.... so the problem is obviously on my iMac.

I can tuck the iMac under my arm and let one of the geniuses in The Hague take a look if I still haven't cancelled out the pop-ups but that is a last resort.

However, I am a great believer in trying to find my own solutions as this is the best way to learn not to make mistakes twice and it also makes me more aware of what I can do in my iMac. Each day of our lives is a learning curve!!!

So any more help before I take the plunge and move over to Firefox etc will be gratefully accepted.
