Good Morning, and thanks for posting. Please be aware that this is not a forum for asking general technical questions (and I had moved your post to the more appropriate forum), but we are still willing to help, if possible. If you you need a good AV program, try either Avast (
http://www.avast.com) or Avira (
http://www.avira.com), they both have free versions for personal (non-commercial) use.
Thanks and
God Bless,
The Board Admins
