Statements:
1) Virus may also come on MacOS X, even if currently there is no known virus infection on our plateform. Therefore it is not a bad idea to have antivirus SW on your Mac with uptodate definitions.
2) If you use VPC you are vulnerable to Windows viruses.
3 _my statement_) There are other risks... the first one being the risk to lose your data due to hardware problems. Therefore it is a very good idea to backup your data on a regular basis.
