How can I remove tradeadexchange malware?

Do not install Sophos, which is just another worse-than-useless "anti-malware" product. Never install any such product for any reason.

I would completely disagree that it is worse than useless. It depends on the A-V and the purpose to which it is being put. But did you not read that I suggested running it for the purpose of scanning for adware? What would make it useless for that? When are you going to start supplying real evidence for the position you take against running a program to scan for adware?

Adblock Super is definitely adware, and should be detected by Malwarebytes Anti-Malware for Mac. I'm guessing that you may have installed this after the last scan with Malwarebytes Anti-Malware for Mac, in an attempt to fix the problem, but that will only make it worse. Within Chrome, choose Window -> Extensions, then click the little trash can icon next to the Adblock Super extension.

I don't recognize any of the others as known adware, but there are a number of extensions there I'm not familiar with, so you'd be wise to turn them all off and test. You can do that in the same extensions list by unchecking the Enabled box next to each extension. If the problem goes away with all of them unchecked, one of them was the culprit... you'll just need to re-enable them until you've found the one causing the problem.

It's also entirely possible that the issue isn't related to any of your Chrome extensions. Does the issue also happen in Safari? If so, it could be a network hack, as John has suggested. A good test of this is if it happens in all browsers, but if you go to another network (coffee shop, local library, friend's house, etc), the problem goes away. If that's the case, some network device on the network where your Mac experiences trouble has been hacked.

I understand your confusion. If I were you I would scan with Sophos, which has an excellent reputation, or again with Malwarebytes for Mac, and then uninstall Sophos, should you want to. Running an A-V for a possible post-infection event is a completely valid reason to use an A-V. I don't think it will cause any harm.

Anyway, I'm not going to respond any more to these groundless challenges you have been getting. I've said everything I need to on the subject.

How am I to judge?

ASC provides a very crude and unreliable way to judge the credibility of members. It isn't worth much, but perhapsin a case like this it's better than nothing. Beneath each member's icon, or "avatar," is a "reputation" rating. Compare.

If you've stopped getting popups in Chrome, then the problem is solved and you don't need to do anything else. If you're still getting popups, keep removing extensions. The most efficient way to proceed, if you have many of them, is to save a complete list, then remove half the items on the list. If the popups stop, you know that the bad extension(s) are in the group you removed. Otherwise, remove half of what remains. By iterating in this way you should be able to isolate the culprit.

Please remember that Linc is expressing his opinion, one that is not shared by others here.

Good question, there are many opinions here, but few are from people who insist that everyone else is wrong, make your own decision about that.

Is it not like comparing nothing to nothing? If you are trying to make a point I find it very obtuse. The only solid correlation of points accumulated by any individual is a reflection of their activity on these forums. Since all participants start at level one, I submit that there may very well be level 1's who are more technically competent that some level 10's. I would rather compare the substance of the advice offered than the number of points.

Ciao.

Yes, but the best you can do is to try to ignore all the noise. I think you might have a decent idea what the "noise" is. Stick with what thomas tells you--more than anyone else here, he knows what he's talking about.

No fight, just a reminder that everyone has an opinion, nothing about one makes it more valid than another.
