Proxy software?

How I can bypass the proxy server in my shelter for online games? Blocks to the security features of games online (ie, cut prevention systems like Game Guard) so I can not update. The result is that I am unable to enter the game. Does anyone can recommend a freeware software virus free bridge to prevent this? Thank you very much!
