                                                          Most antivirus programs stay current though updates. So as far as the 'latest' one just make sure you keep your current one updated for optimized protection. Also, keep in mind that most computer issues come from malware. So if you are in the market for an antivirus program make sure that the one you choose includes malware protection.
