You probably take many steps to protect your computer from getting a virus, but what about your cell phone? Cell phones are basically mini-computers, so, believe it or not, they too can get viruses.

“Viruses and malware（恶意软件）should not be a major concern to the average consumer who uses their device to make phone calls, take pictures, and download a few well-known apps from the major app marketplaces,” Tim Katsch Vice President of iDropped said. “If a user is downloading a lot of apps, changing and exploring settings within the device, and visiting a large number of websites from unknown sources, virus and malware protection should be kept on their mind.” If your phone gets a virus it can mess up your data, put random charges on your bill, and get private information such as your bank account number, credit card information, passwords, and your location.

The most common way that you could get a virus on your phone would be through downloading an infected app. Viruses can also get on your phone when you click on strange links or open up an email that contains a virus. Connecting to an unsecured wireless network in a public place is also a way for hackers（黑客）to get private information from your device.

If you're still convinced that your phone might get a virus, there are anti-virus apps that you can download that will constantly scan your phone to make sure it hasn't developed a virus, Apps like these will also check things before you download them to ensure that they are safe. Another tip is to always look over your cell phone bill every month to make sure there aren't charges from apps that you never downloaded.

Technology is getting smarter, but so are hackers, and it's important to always be cautious with anything you do on your phone. Many people store a lot of personal information on their phones, and while that might make life a little more convenient, it can also do a lot of damage if hacked.

Artificial intelligence can predict when patients with a heart disorder will die, according to scientists.

The software learned to analyze blood tests and scans of beating hearts to spot signs that the organ was about to fail. The team, from   the UK’s Medical Research Council, said the technology could save lives by finding patients that need more aggressive treatment. The results were published in the Journal of Radiology.

According to the researchers, high blood pressure in the lungs damages part of the heart, and about a third of patients die within five years after being diagnosed. There are treatments: drugs, injections straight into the blood vessels, a lung transplant. But doctors need to have an idea of how long patients might have left, in order to pick the right treatment.

The software was given scans of 256 patients’ hearts, and blood test results. When this data was combined with eight years of patient health records, the artificial intelligence predicted when patients would die.

The software could look about five years into the future. It correctly predicted those who would still be alive after one year about 80% of the time. The figure for doctors is 60%.

The team now want to test the software works in other patients in different hospitals before assessing whether it should be made widely available to doctors. The researchers also want to use the technology in other forms of heart failure, such as cardiomyopathy, to see who might need a pacemaker or other forms of   treatment.

Dr Mike Knapton, from the British Heart Foundation, said, “This exciting use of computer software in medical practice will help doctors in the future to make sure that patients are receiving the correct treatment before the condition deteriorates and leaves them needing a lung transplant. The next step is to test this technology in more hospitals with heart disease.”
