try these proxies :
*www.url1.in
*www.kproxy.com
and www.easyorkut.info
in easyorkut we see orkut being opened,so look at the top where you will find an url entry block,there type your desired address
coming to first two proxies copy and paste your desired url in the url entry block displayed by those proxies and start browsing even here also it displays msg saying blocked page,then paste that link again in proxies
for ex:
if you paste *rapidshare.com/bgp.avi then after this if it displays some blocked msg then look for the url that was found in that blocked page it may be look like this
*rs99.................... something like this so copy this link and paste in proxies this helps you i think for downloading exe files,
i can provide you one more technique where,you can use https instead of http,
