The company claimed that regular anti malware scans of its servers failed to spot the malicious programs, which included a malicious downloader programs, Trojan horses, backdoor programs and password stealing key logging programs that target massively multi player online games like World of Warcraft. In a blog post, Bestuzhev said that free hosting services are popular among criminals who are looking to upload and disseminate malicious programs.
