“Luckily, Android Market is full of security apps, many of them free, that provide at least a basic layer of protection. Most of these will scan newly downloaded apps for viruses and spyware. Many also offer paid versions with additional features, such as the ability to remotely erase your phone if it goes missing. (Before signing up, make sure you’re not buying services you’re already getting through your wireless carrier or other sources.),”

Mac computers hold a reputation of being resistant to the infection of computer viruses and threats that are constantly attacking many computers. Some computer users believe that the Mac Operating System is simply more secure than other operating systems, the main reason is that hackers have simply preferred to focus on the most widely used operating system, and we all know that that is Microsoft Windows. At present, the increasing popularity and gaining market share of Mac computers, viruses and malicious software affecting Apple computers are increasing.
What are the types of viruses affect Mac computers?
According to computers experts, there are several types of viruses that can cause a Mac computer to crash. These threats take advantage of security flaws in Microsoft Office and they can also have negative effect to Mac computers when the programs are used on those machines. Another source of viruses are browser plug-ins that are used for viewing animated Flash and PDF files that can also pick up possible threats. Other files that contain trojan horses, spyware and worms from downloading torrent, pirated software, games or adult sites can also infect Mac computers.
How to protect you Mac against viruses?
At present companies such as Symantec, McAfee, and Intego have developed and released virus applications to protect Mac computers. These companies make products that help computer users to protect Macs from threats and viruses. These applications can be bought or downloaded for free directly from the company websites. If your computer system is already infected with a virus, you can also make use of virus-removal applications to track and eliminate the harmful programs on your computer. The best way to prevent a virus is to be careful especially when it comes to visiting websites that you are not sure about their security. Do not open attached files in e-mails especially if you do not know who sent them to you. Try to download security updates for your computer system and browser. Lastly, avoid downloading files from torrent or meta-search engine sites.

Getting anti virus protection has always been something that’s been left to you, the private citizen trying to protect his interests with a product chosen from among dozens on the market. But now, there’s a new trend that appears to be starting up – with at least one player to begin with. Comcast, the cable TV and Internet service provider is starting to roll out nationally, a service that will monitor your connection for you for any activity that matches the profile of what botnets do. A botnet is a kind of malware that is placed on hundreds of computers connected to the Internet. They are controlled by one entity at a remote location that bids them to do all kinds of undesirable things – like sending spam mails abroad.
Should this worry you? Since regular antivirus protection keeps an eye on your computer by completely keeping your hard drive under its control, does this mean that you’re going to have Comcast snooping into your hard drive? Not exactly. And even if the company tried, it couldn’t get away with it. This plan is different. Botnets are was most dangerous threats on the Internet today. It can be very difficult for an individual to catch a single bot on a single computer. Because they are designed to kind of change form rapidly so as to evade detection by regular anti virus protection. They’re not exactly viruses. Viruses are supposed to just attack your computer, bring on a certain kind of damage to your computer and to propagate. Botnets aren’t designed to do any one thing. An infection just places one invisibly on your computer, and it keeps in touch over the Internet with the designer who made it. The designer can manipulate to do his bidding. It’s pretty science-fiction like stuff.
At first, Internet service providers like Comcast tried to battle the problem by giving their subscribers free antivirus. But regular anti virus protection didn’t really succeed in tackling the problem, so frequently do bots change to evade detection. So, now they want to try to protect you – on the network level. When the Comcast central server sees that there is a certain kind of behavior coming in from all kinds of customer computers, it’ll be able to spot a pattern and raise an alarm. There are other things it can do too. If a botnet tries to take over a customer’s computer to be able to turn it into a spam-sending machine, the server will be able to notice that there is an unusual amount of e-mail activity there. And it will be able to shut it down.
So what will Comcast do once it finds out that your computer is infected by a bot? They’ll charge you $100 to clean your system up.
