Check here the possible attacks :
- boot sectors
- files
- macros
- disk clusters
- batch files
- worms from script languages
- trojan horses

The virus types are:
- Polymorphic Viruses
- Stealth
- Multipartite
- cavity viruses
- tunneling
etc...

Basicly the antivirus protection program can be windows service and application which control it. Or just application (without service). You have to:
- monitor the memory
- monitor the file system
- incoming/outgoing mail
- downloaded files
- files with scripts (for e.g. Visual Basic)

And one of the most important part is the virus definitions. They have to be permanently updated because new viruses come up every day. They have to contain all the information needed to detect the virus - for example number of bytes written in the infected file, disk sector or ... make universal record about this.
