[The Mekon (John Briggs)]

Having searched this forum, I know this has been done in the past, but the most informative threads are over two years old, so -

What anti-virus software is recommended? I am not running anything at present and I recently have had one person tell me my laptop is infected, another that my memory stick is.

Previous posts recommended Nod32 and Avast.

What is new in this area? - I do not mind paying, in fact I prefer to buy in shop so I have the base program on disk.

All suggestions welcome, I am not very computer savvy.
