So this started 3 weeks ago? When I open up youtube, mostly youtube only, very rare for other websites. I get this error message. Then after refreshing once or a couple times, youtube loads. I also get this problem in firefox. How do I fix this? It's getting tedious. I Have AVG Pro and scanned my computer, nothing, I downloaded and used Malware Bytes, nothing has changed. Could it be the way I set up my Wireless Router? I got a new Wireless Router and then I started to see this problem I beleive. I didn't know how to set up my wireless but I managed to get it working though at the time. I got the D-Link 615 Would like some help. :S
If I had to guess I'd say it's a browser issue, chrome has problems with some sites. Make sure you clear your cache and everything, and I'd check the faqs and bug reports out there, that might help.
