Foxit warned that a malware claiming to be Foxit Reader for Macintosh has been perpetrating attacks on users thinking they were downloading an official version of the free PDF reader. The thing is, there’s no Foxit Reader for OS X. The software is available for Windows, Windows Mobile, Embedded Linux, Desktop Linux, and U3. "While imitation may be the sincerest form of flattery, we’re not happy about the recent malware attacks masquerading as our Foxit Reader," said George Gao of  Foxit Corporation. Trend Micro researcher Ivan Macalintal found the malware and classified it as a variant of the JAHLAV DNS trojan, a Mac malware.
