Hi Peter, what i would reccomend you is to use AVG or AVAST anti-virus softwares, they have versions available and they are FREE!! So, worth having them most for removing your virus from your pc and detect new viruses that might show up later on!! Since this is my first post here i can't give you links to search for, but if you search on Google you can find lists of softwares which can be of great help to you.
