Starting today, every thread I comment on...
 

...has ad links added to it?

The few posts I have left this morning, I post them and the board is turning certain key words into links to amazon and ebay.

Do I need fire up my anti virus or do I need to find a new rx7 forum?

I'd try another browser,download it and see that fixes anything.
Wipe the old browser,then reload it again.
I run into problems all the time.
I've had to wait like 5 minutes to move from section to section..(other forums..just fine though..)

Try deleting extensions from your browser settings.. failing that go into programs through control panel and delete the most recent oddball looking programs.. Sometimes they get into windows programs and it becomes almost impossible to get rid of.

Sounds like you inadvertently downloaded Google Adwords on to your computer. This is not something the forum added to your computer.

Remove text Enhance program from your computer.
a. Click on Start button, and navigate to Control Panel.
b. Select Programs and Features from the Control Panel.
c. Select any Text Enhance plugin from the list of software, and click Uninstall/Remove.

My kids clicked something to bring google ad on about. I remember it being very easy to get rid of. It was listed as an extension like revalot said.
