在现代防病毒软件中，它始终是方法的组合。基于签名的检测有助于检测已知病毒，节省检测时间并消除至少已知病毒的漏报;启发式方法有助于检测未知和多态的方法。

In modern anti-virus software, it's always a combination of methods. Signature-based detection helps to detect known viruses, save time on detection and eliminate false negatives for at least known ones; heuristic methods help to detect unknown and "polymorphic" ones.
