"Security researchers have detected a new malware campaign that attempts to infect Skype users by sending them booby-trapped links from contacts in their address book.
"Microsoft is telling Windows users that they'll have to reinstall the operating system if they get infected with a new rootkit that hides in the machine's boot sector.
A new variant of a Trojan Microsoft calls "Popureb" digs so deeply into the system that the only way to eradicate it is to return Windows to its out-of-the-box configuration, Chun Feng, an engineer with the Microsoft Malware Protection Center (MMPC), said last week on the group's blog.

In fact, about one out of every 14 programs downloaded by Windows users turns out to be malicious, Microsoft said Tuesday. And even though Microsoft has a feature in its Internet Explorer browser designed to steer users away from unknown and potentially untrustworthy software, about 5 percent of users ignore the warnings and download malicious Trojan horse programs anyway."
"The idea is that ISPs could detect signs -- say, by intercepting outbound spam, or botnet command-and-control traffic -- and cut the infected customer off from the internet. The user would be placed in a walled garden, where a web browser would only be able to see certain pages, which give instructions on how to fix the problem.

Pedophiles can exploit virus-infected PCs to remotely store and view their stash without fear they'll get caught. Pranksters or someone trying to frame you can tap viruses to make it appear that you surf illegal Web sites.
Researchers with BitDefender are tracking the emergence of a new spate of phony overnight delivery notice attacks, calling out a set of threats currently in circulation that attempt to create backdoors that leave affected machines almost completely under the control of their assailants.
