SB Nation has identified the issue affecting Purple Row and the rest of the network. Everything should be back to normal soon.
Basically, something (probably an ad or something of the like) is throwing false positives to the malware warnings that Chrome, etc have built into them. There ISN'T a malware attack happening (we've been assured of this by our tech team, else I wouldn't be sharing it with you), but some browsers might be having trouble getting past that malware warning.
You should be able to access threads normally using Chrome by clicking "Proceed Anyway" when the big red warning page comes up.
If you're not confident in this, and I won't blame you if you aren't (what with the internet and all), you can still join us in threads using the SBN Android App or through the mobile site at http://mobile.purplerow.com.
