When attackers look for vulnerabilities, they target popular software. Why bother chasing flaws in applications that few people use? One friend runs a third-party application instead of Adobe Acrobat Reader to open and read PDF documents. Another friend runs the Maxthon browser to stay out of the way of exploits that target more popular browsers. The worlds most secure software programs usually rank among the least popular, even when they are free and functional. Most hackers and malware are successful not because of new vulnerabilities, but because of vulnerabilities for which patches were released long ago.”]
