Hi curious mew,
Leave WOT and AdBlock Plus out.
Disable the extension by checking the right hand Enable box to stop running the 3 remaining items.
Test 1 by 1 to know which is the culprit.
The link may be infected.
Warning before downloading of files from any Cnet links is good.
Trust me. My laptop which is now totally rendered corrupt was infected from CNET on 28th Dec.2012.
CNET could not care if ppl left malware in the free to try and trial period programs in their system
I did not even download anything and only read the program review. My laptop was infected.
All my browsers will leave a html command line promoting the program and auto updating of the command line whenever I am online.
