At which stage I rightclick the Help file and select create shortcut. I copy the shortcut to my desktop so it is easily accessible. On the first page of the Help file, at end of page, the differences between Home and pro are outlined. (See screenshots).
There are a lot more virus than conficker. All antivirus (AV) and antispyware (A/S) companies take on responsibility for protecting users and networks from the threat of malware dissemination and perpetration. Alwil Software (avast) rate very highly in respect to the responsibility they take on, and the commitment they make to provide up to date protection for computers like the one you are posting from. You can be assured that they are doing their utmost to rid us of viruses like conficker and the rest. They do this on a 24 hour 7 days a week basis.
