scorecardresearch.com and b.scorecardresearch.com is a Malware/Trojan. You are seriously infected with a virus there. It is embedded in advertiser code somehow - I'm not that much of an expert to know exactly how. It can infect your computer when you view the webpage and nothing blocks it. Apparently scorecard is a tracker, it records where you go on the internet and more malicious versions of it are also a keylogger which can be used to snare your log-in passwords and stuff.
This may help you with removal ---> [link] Or here ---> [link] Other than that - I dunno, you'll probly have to get someone more proffesional to help you - or wipe your computer and reinstall.
Personally I use Firefox, with NoScript - and it was NoScript that alerted me to Scorecard's presence and its attempts to redirect. When I copy/pasted the url in my address bar, Malware Bytes blocked it and told me it was a malicious redirect. Researching further into this - it looks like this might be a new little monster that has been born somehow. So, ppl are catching it frequently and spreading it around like wildfire.
I have told the DA ppl about this nasty virus. So I guess they are aware of it. I filled out a ticket for it. Malwarebytes is a very good anti-malware/spyware program that can help you clean up there. It is free - but I purchased it because it saved my computer when it became infected with the RelevantKnowledge virus (which I think also came from DeviantArt)
Do not post in old threads Threads that have been inactive for longer than 2 months are considered "dead" and should not be posted in. Feel free to post a new thread with the same topic. Posting in a thread that has been inactive for more than 2 months is called "Thread Necromancy" and doing so will result in the thread being locked.
I'm sure deviantART doesn't control the ads they display. That's why you can report certain ads that are not appropriate or give you viruses (Scientology and... well, that ad that gave you viruses, respectively).
