Since Friday, more than half a million Trojan horse programs disguised as media files have been detected on consumer PCs, according to McAfee Avert Labs.
"This is one of the most prevalent pieces of malware in the last three years," said Craig Schmugar, a McAfee Avert Labs researcher, in an e-mailed statement. "We have never before had a threat this significant that arrives as a media file."
The Trojan malware, Downloader-UA.h, was added to the McAfee database several days ago. In the past 24 hours, it has been detected by McAfee VirusScan Online on more than 119,000 computers out of almost 436,000 scanned, an infection rate of 27%. Other malware McAfee is tracking exhibits an infection rate in the 1% to 5% range.
