You will get lots of different ideas about thois - almost as many as people able to post.
As far as AV is concerned - they are all much the same now.
Kaspersky is known to be one of the better paid version of AV, lots like Avast for a free one.
I use AVG8 paid version but the free version is almost the same less control of updates etc.
For Anti-malware - AVG8 has one included but MBAM is very good and in the paid version has a resident scanner. Winpatrol is also a good Anti-Malware monitoring system with the added advantage it does not need to be updated. It too has a paid version as well as a free one.
All of them are available from adverts listed on this domain.
