Cannot access Internet Options

Hello,
It seems that in my Web browser, SBC Yahoo, running DSL speed, I cannot seem to right click and cut, copy, or even get to that point because when I right click, I am not presented with any options like cut, copy, etc. I can't imagine where I weht wrong, and I have scanned with Super Antispyware and even Trend Micro House Calls- still no access. I also noticed that I have no access to Internet Options on my pc. Can anybody shed some light on this dilema? It'd got me bewildered, and I cannot go on without being able to minipulate and copy and paste from the Internet. Please help. I'm thinking its either an access I need to re-set, or maybe I have some malicious malware installed on my pc. Any ideas????
