Prime-line to expand Malvern plant, add 50 jobs
Prime-Line Inc. of Malvern said Friday that it will build a new manufacturing facility, spending $6.7 million and adding 50 jobs. The 71-year-old company makes medium- and light-density fiberboard moulding and millwork for nationwide distributors. Its products are sold in retail outlets including Lowe's and Home Depot. The company said it is Lowe's single largest domestic supplier east of the Rocky Mountains. The company said the expansion will give it the ability to produce more than 2 million lineal feet of primed moulding per week. Gov. Mike Beebe, who attended the expansion announcement in Malvern, said the expansion will boost the company's employment to nearly 100 people.

Investors thankful for stocks at records
Stocks climbed higher for a seventh straight week last week, and the Dow and S&P 500 closed at record highs above key milestones. But will investors stay hungry for stocks during Thanksgiving week? Trading volume is typically quiet during the holiday-shortened week. The U.S. markets will be closed on Thursday for Thanksgiving and will shut down at 1 p.m. EST on Friday. Still, stocks have historically moved higher even as investors may be more focused on turkey and football. The S&P 500 has averaged a gain of 0.6% during Thanksgiving week over the past 20 years, according to Schaffer's Investment Research.

5 most dangerous cyber attacks

Small businesses are the No. 1 target for cybercriminals. Here are 6 of the most dangerous cyberattacks hitting small firms. SEO poisoning isn't new, but it is a growing problem for small businesses, according to Banerjee. It begins with hackers isolating keywords that are generating buzz on Google and other search engines. They then create malicious URLs about this topic so that search engines will index it alongside other results. Suppose thousands of people are Googling "Miley Cyrus." In this attack, cybercriminals would create dummy websites about her that are loaded with malware. If you're searching for Miley and unwittingly click on one of these links, the malware could be used to hack into your computer or install spyware, Banerjee said.

Sold! Red Mac Pro for $977,000
Bono called Jony Ive and his friend Marc Newson the Elvis and Beatles of design. Sotheby's Oliver Barker compared them to Donatello and Michelangelo -- referring to the Renaissance artists, I think, not the Ninja turtles. Ive and Newson aren't that famous. But they do have a lot of cachet in the world of industrial design -- Ive at Apple (AAPL), Newson for everyone from Trek bikes to Ikepod watches. And now they've proved themselves formidable fundraisers. A collection of objects the two designers curated raised more than $13 million at a Sotheby's Project (RED) auction Saturday night. That amount was matched by the Bill and Melinda Gates Foundation to bring the total to $26.2 million. All proceeds will go to the Global Fund to fight AIDS, Tuberculosis and Malaria in Africa.
