ReportOne of every 20 computers scanned with the free tool from Microsoft Safety Scanner is infected with malware.
On May 12 Microsoft relaunched a Safety Scanner and the data obtained after an overwhelming 420,000 copies were downloaded in the first week of availability, because samples had signs of exploits or malware on more than 20,000 computers, or 4.8% of the total. So says Microsoft Malware Protection Center (MMPC), which analyzed the data.
Each infected computer had on average 3.5 malware threats, Microsoft considers this a sign that there was a successful attack against the machine.
Out of ten threats found by Safety Scanner, seven were Java exploits, which Microsoft's reports showing a sharp increase in Java-based exploits. According to data from the company the second half of 2010 they detected almost 13 million of these exploits, up from one million in the first half of that year. These exploits showed two vulnerabilities affecting Oracle Java that generated 85% of all attacks of Java in the second half of 2010.
Safety Scanner, which replaces a previous online tool uses the same technology and signature detection as the antivirus program from Microsoft's Security Essentials and Forefront Endpoint Protection business product.
