Internet Options disappearing under Tools in IE5.5

[MOHAN6491]

I am not able to find Internet options under Tools in IE 5.5.
It apears, there is some virus in the system.

In addition to this problem, every program in HTML, is appended with some
stupid VB Script which got appended to it.

Any solution for the above problem.
