Facebook gains $6.8 bn after Zuckerberg‘s speech

Facebook CEO Mark Zuckerberg might need to talk more often. A 30-minute appearance at a technology industry conference earlier this week has translated into $6.785 billion in additional market valuation for his company. Facebook shares finished Friday's regular trading session up 6.2 percent at $22 as Wall Street's confidence in the company continued to improve in the wake of the 28-year-old CEO's first public appearance since a rocky initial public offering in May. The social networking company's progress introducing a new advertising service that gives marketers improved ways to reach consumers on Facebook also helped bolster its shares, analysts said. "People are starting to feel a little more comfortable," said Arvind Bhatia, an analyst with Sterne, Agree & Leach. Zuckerberg's comments, in which he highlighted mobile business progress, suggested Facebook could enter the search market and expressed confidence in future money-making prospects, have…

EBay‘s new logo ‘strikingly‘ similar to Google‘s

Web giant eBay has unveiled a new logo for its website, which has strikingsimilarities with its old one and also with Google's iconic homepage logo. The auction and shopping site has had the same logo since the 1990s, but the redesigned logo looks like little more than a flattened-out version of the old. The logo was revealed by company president Devin Wenig, who said the move reflected a shift away from auctions and collectibles toward full-priced, buy-it-now merchandise. "The eBay logo is known the world over, so changing it was not a decision made lightly. The time felt right," the Daily Mail quoted Wenig, as writing in a letter to the employees. eBay is focusing more on new, fixed-priced sales as it tries to compete better with, which has been growing faster. "It's eBay today: a global online marketplace that offers a cleaner, more contemporary and consistent experience," Wenig wrote. "Auction-style listings, used goods, vintage items a…

New Malware for PCs detected by Microsoft

A customer in Shenzhen, China, took a brand new laptop out of its box and booted it up for the first time. But as the screen lit up, the computer began taking on a life of its own. The machine, triggered by a virus hidden in its hard drive, began searching across the internet for another computer. 

The laptop, supposedly in pristine, super-fast, direct-from-the-factory condition, had instantly become part of an illegal, global network capable of attacking websites, looting bank accounts and stealing personal data. 

For years, online investigators have warned consumers about the dangers of opening or downloading files emailed to them from unknown or suspicious sources. Now, they say malicious software and computer code could be lurking on computers before the bubble wrap even comes off. 

The shopper in this case was part of a team of Microsoft researchers in China investigating the sale of counterfeit software. They suddenly had been introduced to a malware called Nitol. The incident was …

Google buys cybersecurity startup VirusTotal

Google Inc has bought startup VirusTotal, picking up a fledgling but widely used cybersecurity player in a move that could beef up protection for its Internet services.

The acquisition of VirusTotal, which aggregates warnings on submitted files and websites from most antivirus solutions, including Intel Corp's McAfee andSymantec Corp , could significantly shore up the search giant's ability to weed out infectious content from Gmail, social network Google+ and even the pages it shows search users.

VirusTotal operates by accepting requests for virus checks, running every available protection software on the questioned document or pages, then distributing the results to security vendors.
