根据spyhunter 5反恶意软件软件制造商enigmasoft今天发布的数据，美国主要城市上半年恶意软件感染率最高的是亚特兰大 奥兰多和丹佛。enigmasoft研究团队在2018年的前六个月查看了美国spyhunter的感染数据。他们的汇编数据显示，亚特兰大，奥兰多和丹佛的电脑最容易感染。
enigmasoft还研究了各州的感染情况。这些结果表明，受感染最多的州是科罗拉多州，新罕布什尔州和弗吉尼亚州。研究人员表示，很难确切地说为什么一个城市或州的感染率高于其他城市和州。名单上有各种各样的城市。较大的城市，较小的城市和每个地理区域的城市。受感染最少的地区来说，第一是纽约，第二是旧金山。
还研究了2018年上半年受感染最多的一周。星期三感染率最高，星期日感染率最低。在美国电脑上检测到的感染范围包括enigmasoft识别为可能不需要的程序或滋扰软件，一直到勒索软件，这可能会删除有价值的文件，除非受害者支付赎金。
enigmasoft表示，用户需要定期备份数据。理想情况下，用户应该拥有物理备份（连接到计算机的外部驱动器）和基于云的备份。无论哪种方式，请将电脑设置为自动且频繁地备份文件。
