open eclipse Markeplace
eclipse, eclipse-marketplace, java, svn
Solution
I am afraid, it is not proxy. Nor the antivirus. I had the same problem and neither helped. But your Eclipse simply can't reach a site because java 7 by default makes Eclpse to reach it throught the protocol IP6, that is not really supported by Eclipse, at least in versions till 4.3.
Go to cmd, use
setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true
restart eclipse and it will work.
