What are common methods used for malware distribution?

### REPLY:
One effective method for malware distribution is through the use of exploit kits. These kits contain pre-built exploits for known vulnerabilities in software, which can be used to infect unsuspecting users. Another method is through the use of botnets, where a network of compromised computers is controlled remotely to distribute malware. Additionally, malware can be distributed through malicious ads, known as malvertising, which appear on legitimate websites and redirect users to malicious content.
