How to ward off this woman at my place of work? Not Interested...?

[I know nothing]

if she's making unwanted advances to you at work then it's sexual harassment and you are within your rights to report it to the management. but have you tried just telling her look, i'm not interested! ?
as for the rest of it, don't throw your shoulder out of joint patting yourself on the back over how wonderful you think you are. it's very unappealing.

I see you already hate this lady with every thing you have, but just try to commmunicate your lack of feelings for her in a polite way without offending her. It might not be easy but all this would be in an effort to avoid drama. Remember a rejected woman can cause chaos especially if she is so much into you. Matters such as these require a lot of tact and wisdom in handling - remember that she is a work colleague as much as you find her repulsive. At the end of all this she also needs to be treated as a decent human being. It may not be easy but find a nice way of solving this issue. Try to minimise the hate. We all have our positive sides however repulsive we may appear to someone.

So all the women at work think you're a stud muffin, yet in another question you bleat about being bullied & how you can't cope.
