What’s a mobile phone virus?

A mobile phone virus or mobile malware - malicious mobile software - is a computer virus specifically adapted for the mobile phone environment and designed to spread from one vulnerable phone to another.

A virus is a program code that replicates by being copied to another program. Viruses can be transmitted as attachments to an email or in a download file. Some viruses take effect as soon as their code is executed; other viruses can lie dormant. A virus that replicates by resending itself as an email attachment or as a part of a network message is known as a worm.

Viruses can range from benign to quite harmful; they can erase data from the infected phone or send fake messages purporting to be from the phones owner. How prevalent are mobile phone viruses? The current security risk from mobile phone viruses and worms is low.

Until many more smart phones or PDAs are in use, and users of these phones are regularly exchanging executable files, the risk will remain low. The mobile industry takes the threat of viruses very seriously and is continually monitoring its networks and working to protect users from any future risk from mobile phone viruses. There are also some simple measures that individual users can implement to protect themselves.

What can I do to protect my phone?

The following tips can help prevent problems with viruses on your phone:

1. Switch to Bluetooth hidden mode. If your phone has Bluetooth capability, ensure that the Bluetooth capability is switched to hidden or invisible mode unless you specifically need it to be visible. This will help prevent other Bluetooth-enabled devices from finding your phone (unless you grant them the necessary permission) and will therefore help protect your phone from worms that spread using the Bluetooth wireless technology.

2. Exercise caution before opening

...Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular. Tablets are available on the 3G and 4G networks.

...cell phones, and after spending an extended amount of time doing the research, the findings negating cell phone safety was irrefutable. I think that since cell phones are such a highly debated topic, it was an awesome subject to tackle, and I hope this paper can help people think twice about cell phone safety. Unseen Dangers: The Reality of Cell Phones The Industrial Revolution marked the beginning of modern technology, creating fruitful moments in history that paved the groundwork for the Information Age. The advancement of computer chip technology allowed us to create the modern day cell phones, revolutionizing the concept of communication. Today our lives depend on these mobile phones, which have advanced into mobile-computers. Despite the beneficial uses and entertaining characteristics of the mobile phone, the devices are highly debated over their potential health risks. As the device becomes pervasive in modern society, it is important to more fully understand the potential health hazards that growing evidence suggests, and to ultimately reevaluate the information that industry funded and tailored studies supply for the public in the United States. Are cell phones the pinnacle of wireless communication, or what if these contemporary devices increase the risk of life-threatening illnesses for billions of people worldwide? The rapid development of communication technology has created extraordinary conveniences for our everyday lives. George Zysman provides an excellent explanation...

However, the design for the ShopWSS.com emails was not responsive to the device. See how the marketers took their active cart abandonment email and optimized it for mobile, and how through A/B split testing, achieved an 8% lift in conversions from responsive emails. by Courtney Eckerle, Manager of Editorial Content CHALLENGE ShopWSS.com, the e-commerce arm of WSS — the new name for Warehouse Shoe Sale, a 62-store chain mostly located in Southern California — has only been up and producing measurable revenue for about the past three years, according to Erica Forrette, Senior Manager of Digital Marketing, ShopWSS.com. "There was a re-platforming at the time … I joined the company about a year-and-a-half ago and my role is to drive traffic and sales through online channels and mobile channels," she said. Because of that transition, the team began harvesting more insights into email subscribers, particularly what devices they were using to read WSS emails. "We found that a really high percentage, close to 70% of people, were using mobile devices to read our emails, so it became pretty clear that we needed to optimize our email creative," she said, adding that around 50% of site visitors are viewing on a...

...physical changes to occur most definitely. “Projected screens and keyboards that can be used on walls and other surfaces are also a given. As are hologram projection screens and keyboards, both 3D and flat (Baker, 2011).” As bulky and spacious as PC desktops are, there are also positives about them as well. One reason you won’t see PC desktops vanish is because of their ability to process and store much more than any mobile device. A mobile device just can’t handle as much as a regular computer can. A lot of that has to do with the fact that researchers are having a difficult time trying to give mobile devices the same “power” as a desktop computer but in a much much smaller space. The main reason manufactures want to claim the desktop as being dead is because they want their product (mobile devices or wireless notebook/tablets) to sell quickly and then they can be off to the next adventure with the new products in town. There will come a time when the desktop will finally see its end in the technology world but until researchers can figure out a way to get mobile devices to act and manage as a desktop computer, then desktop computers are far from being extinct yet. For example, I can’t print from my cell phone (at least not to my knowledge!) therefore I have...

...Mobile Computing and Social Networks CIS 500 June 4, 2012 Mobile computing and social networks are not only good for keeping in touch with friends and family or playing games, but business have also gotten on the band wagon and developed apps to conduct work. One of the apps that are being used often is geo-location. This type of application is a technology that uses data obtained from an individual’s mobile device to identify or describe their actual physical location at a given point in time. This app benefits not only the business that uses them but also the general public who has it downloaded on their phone. It’s efficient for us as customers because we can receive information that is instantly relevant to a purchase decision, to location-specific discounts and services (Jaiswal & Nayak, 2010, p. 1). Business use this for marketing strategies in order to get new customers and returning customers to keep coming back and making purchases. Other ways that business uses geo-data are Know Your Customer (KYC), delivery and assessment management, cloud balancing, content customization, vehicle Ad Hoc Networks, and Real-time incident management just to name a few. It has become easier and easier to capture this information due to the ability of mobile phones, GPS devices, even swiping are debt or credit cards. Every time we use one of these devices information goes into a data warehouse for businesses to use. There are two ways that geo-location data is...

...Mobile Technology and Social Networking in the Health Sector Introduction Rapid technological advances have brought about a new twist of operation in the health segment. Mobile computing devices and other portable devices such as iPods and iPads have redefined the relationship between computers and human beings. These technological advances signify substantial evidence of departure from computational paradigms, which necessitated users to explicitly interact with computing systems to achieve the expected results. The health sector is also demonstrating its pursuit to be in tandem with the changing technology. By using advanced methods, which are not substitutes, but techniques to improve monitoring of patients health, the sector has demonstrated the efficiency of the use of technology to monitor patients’ status even while at home. This global integration of operations from different applications enables data sharing, via image, and voice outputs. According to Magal and Word (2011), patient monitoring is indispensable to any health facility. Several departments are equipped with electrical and computing devices that facilitate the monitoring of patient status. Not only are these facilities meant for use in the health centers, but also, technology has opened up other platforms through which patients can share their experiences with other patients of similar conditions, and monitor their health progress without the need of visiting health centers physically.

A mobile app may be a mobile Web site bookmarking utility, a mobile-based instant messaging client, or many other applications. I recently upgraded my Smartphone from a Blackberry device, to a phone with the Android operating System, a Motorola Droid Maxx. I was stunned to find so many applications that I could download and use for free. Since I upgraded my Smartphone to the Motorola Droid Maxx at the height of gas prices barreling out of control, I wanted to find an application that could assist my family and me, in finding the cheapest gas station around my current home since I primarily fuel at gas stations near there. In the past, I used to drive to different gas stations in the neighborhood to check the prices of each station until I found the one with the cheapest prices. At times I ended up driving back to the previous station to get the lowest prices. The gas stations are only a few short blocks or up to ½ a mile away from one another so it was not a big burden to drive back and forth. The first thing I did was research apps and find an app that...
