World’s nastiest trojan fools AV software
One of the world’s nastiest password-stealing trojans evades detection by the majority PCs running anti-virus programs, according to a study that examined 10,000 machines.
A recent report estimated that Zeus is the No. 1 trojan, with 3.6 million infections in the US alone, or about 1 per cent of the installed base of PCs. Trusteer’s study, which found Zeus accounted for 44 per cent of the banking malware infections, was consistent with that finding.
