First, never use any kind of "anti-virus" or "anti-malware" software on a Mac. That's how you create problems, not how you solve them. Remove whatever you installed according to the developers' instructions.

Is Safari affected, or only Chrome?

Be advised that Malwarebytes Anti-Malware for Mac is not an anti-virus or anti-malware application. By making this statement, you may be confusing the OP and others as well. Don't you agree?

Ciao.

Follow dominic23's original advice.

There are some who apparently do not fully understand what Malwarebytes Anti-Malware for Mac actually is. Malwarebytes Anti-Malware for Mac is a search and identification tool that will find adware that may have been installed on your Mac. It is essentially is 'use it once' application for a specific problem. Anti-virus and anti-malware applications are permanently installed and either run continuously or periodically in the background and in the case with Macs, can degrade performance or actually corrupt the operation of the Mac. Malwarebytes Anti-Malware for Mac does not have such attributes.

Ciao.

I have run Malwarebytes, Admedic, F-secure and ClamXAV, none of which detected anything.

When you say that you have run Malwarebytes and Admedic, are you referring to https://www.malwarebytes.org/antimalware/mac/

But be advised that it will not run on any operating system lower than Lion, OS x 10.7, so if you are running Snow Leopard, it will not run on your machine.

I strongly doubt that your having used Malwarebytes Anti-Malware for Mac (Adware Medic) caused any problems. There is no evidence anywhere that it does. Besides that, even though its name would lead one to think so, it is not, at least at present, an anti-malware program; it is currently designed strictly to remove adware, not malware. It is also extremely unlikely that ClamXav, which is an anti-malware application, caused any problems. Consequently, there is no need to uninstall either.

Open Chrome and enter the following in the URL field, "about:extensions" no quotes. What is listed there?

Normally I would suggest that you disable them one by one, which would be very tedious, since you have so many (many of which I'm not familiar with) or in groups of halves, and test for the tradeexchange behavior. However, since you say that this has only started beginning a few weeks ago, I would disable any that were updated around that time and test. Could be that one of them started doing this. If that doesn't do the trick, then disable them in groups of halves and test, in order to narrow it down to which one is responsible.

I don't use Chrome very often, but I don't understand why you need three adblockers. Also, I don't know if Speed Dial 2 is related to Speed Dial (FVD), but I do know that extensions by the developer of FVD (Flash Video Downloader), in Firefox, have a very poor reputation for installing extraneous junk, adware, with their programs. But maybe completely unrelated.
