Chrome: waiting for available socket

Google Chrome opens twitter stream without pictures and writing below "waiting for available sockets":

I have multiple connections opened, most of the are by avp:

avp.exe is possibly either Kaspersky antivirus or a trojan that has infected your PC. There's no need for a genuine antivirus program to make connections to so many different external IP-addresses. Alternatively it may be part of a peer-to-peer program you have installed that is overloading your system.

Kaspersky avp.exe does intercept web-page connections to check for viral payloads, so the avp.exe lines may just be a misreporting (arguably) of connections made by chrome. In which case the real problem may lie elsewhere.

If you have Kaspersky installed, I'd try uninstalling Kaspersky and installing either the latest version or a competitor, perhaps just Microsoft Security Essentials, at least until the problem is resolved.

If you think it is a trojan, follow the guidance in How can I remove malicious spyware, malware, adware, viruses, trojans or rootkits from my PC?

There have been problems reported with Chrome that have similar symptoms

You can visit chrome://net-internals/#sockets and try flushing connections. Then retry accessing Twitter.

It might be bug https://code.google.com/p/chromium/issues/detail?id=162627 if twitter feed embeds enough <video> or <audio> elements. If this is the cause, the only real fix is to use another browser.
