Redirect Virus

Hi, I am constantly plagued by a redirect virus or viruses.  I am not proficient enough to follow the advice I've found and this is why I pay for full Norton cover.  Even the Norton product advice for this problem does not solve it as far as I am competent to follow at any rate.

Somebody please give me a solution I can use with my Norton product to resolve this and update the scanners to cover this.  I am very surprised that this has happened as I have had no other problems with viruses despite numerous attacks
