Some sort of scam call

A company called from 234-567-7890 saying they were ZTech Solutions and a person who said he was Boris Norman claims they work with Microsoft; they wanted to take control of my computer and download a bunch of software including Malwarebites for a mere $400.00 and that this would solve any computer problems I might run into even better than McAfee and Norton. I had a funny feeling about them and didn’t follow through. Other numbers they have are 210-234-4604 and 845-440-1804

the same company called me the week of 8/1/11 and are still calling from number +011 asking for 200.00 to clear my error n warning off my computer

When combined let you send untraceable phone messages (text converted to voice) to these companies that are bothering you. This is not spam. I don't work for anyone. This is a illegitimate way to even the odds.
