No need to get it, unless you want to do that too. However, if you want to use the free AV client from, you can follow this procedure: - with a computer on the internet, browse to and start the download - open the temp folder by clicking start-> run and choosing %temp% as the value - look for new folders and files to be created, this is what you need - once the 'one time' AV scanner starts, you can close it out. (Can't say that about MBAM!) Don't forget you probably get 10 free with your firewall. The AV is very good and hasn't had a false positive in some time. You should purchase the EMS client, it is excellent! The Vulnerability Management and web filtering is easily worth the price.
