Proxy threath and drawback
The proxy, in general case, is transparent (invisible) to the client and server programs, except that
performance may be decreased slightly and they may have to be
configured to use different tcp/ip port numbers and host names or IP
addresses. Sometimes proxies only filter a kind of connection
like browser (port 80) and not other, so you can not for example use
https.
DO NOT use one of the anonymous open free proxy lists.
While thinking that you have made yourself more secure, you have
actually opened yourself up for attack. When using an open proxy
server, your PC is making a direct connection to another computer. You
also do not know who is in control of this computer. Your passwords can
be sniffed and your firewall tunneled. Your privacy can also be invaded
as this person reads your email, snags your ICQ, IRC, AIM, MSN messages
or any other unencrypted data.
