Mobile devices security

Written by Mike Ber

As this security solution is not such a great idea, other companies have researched, and finally found a new way to prevent cell phones and PDAs theft. This method permits to remotely disable up to four different tasks of a stolen cell phone or PDA, rendering it inoperable. But atrepparttar same time data contained inrepparttar 143262 device are locked. The beauty of this option is thatrepparttar 143263 unit is not damaged in any way - full functionality and data can be easily restored ifrepparttar 143264 device is recovered. Thus,repparttar 143265 device is useless torepparttar 143266 thief, but it can be reactivated and restored if it is recovered and returned to its rightful owner.

Another new security breach has been encountered this year when reports were received about a backdoor Trojan horse program that can take control over a mobile device. This isrepparttar 143267 first known backdoor Trojan horse for PDAs. The subject program, identified as Backdoor.Brador.A, attacks PDAs runningrepparttar 143268 Windows operating system. And like all backdoors, it cannot spread by itself. The Trojan arrives as an e-mail attachment or can be downloaded fromrepparttar 143269 Internet. Also, it has a complete set of destructive functions characteristic for backdoors. After it is installed, this small program is activated whenrepparttar 143270 PDA is restarted and begins to look for a remote administrator to take control ofrepparttar 143271 device. Security specialists claimrepparttar 143272 virus was written by a Russian virus coder since it was attached to an e-mail with a Russian sender address and contained Russian text. Fortunately,repparttar 143273 Trojan’s threat control and removal was rated as "easy".

The important thing about this virus is notrepparttar 143274 number of devices affected, because this number is very small, butrepparttar 143275 fact that this isrepparttar 143276 first one that appeared onrepparttar 143277 "market" is considered to be very important. We have to admit that it is hardly surprising that viruses have found their way to mobile devices. This isrepparttar 143278 natural trend. Where technology goes, viruses will follow. Asrepparttar 143279 new technology shifts intorepparttar 143280 mobile market, these threats will move in that direction also. The specialists fromrepparttar 143281 Kaspersky Labs claim they were expecting a virus attack on a PDA, due torepparttar 143282 latest attacks against other mobile devices. Now,repparttar 143283 PDA users look at a real danger and it is a well known fact that interested intruders will grabrepparttar 143284 chance to attack PDAs and mobile phones inrepparttar 143285 near future. Virus threats development for mobile devices is passing throughrepparttar 143286 same stages asrepparttar 143287 one for desktops.

Antivirus Software

Written by Mike Ber

Nowadays more and more people are using a computer. A lot of them use it at their work place, but an increasing number of computer users have also discoveredrepparttar need to have a computer at home. Atrepparttar 143261 same timerepparttar 143262 number of Internet surfers increased. This is a good thing because people are realizingrepparttar 143263 advantages offered byrepparttar 143264 world of technology. As soon as they discover this, they start using computers andrepparttar 143265 Internet more and more, but atrepparttar 143266 same time not consideringrepparttar 143267 threats that are coming in from all sides. They should know that if you don’t protect yourself, nobody will. These threats are now coming from everywhere and they are growing in number and complexity. First threats of this kind wererepparttar 143268 viruses. At first, viruses were not that harmful. They were designed to perform a simple task, like flashing a single message ontorepparttar 143269 user's computer screen. Alsorepparttar 143270 spread rate was slow, because not many people were connected torepparttar 143271 Internet. But nowrepparttar 143272 majority of viruses are programs intentionally written to obstruct with, or harm other programs or computer systems. And they are spreading very fast.

Many companies and people have had a lot of troubles because of these viruses. And sorepparttar 143273 need for antivirus software was born. At first one very simple antivirus appeared and this was enough. Now, asrepparttar 143274 threat is growing antivirus software are becoming a lot more complex. Some of them have also included a firewall so to better protectrepparttar 143275 users. In order to increaserepparttar 143276 competition, other antivirus software producers have also come up with a wonderful idea: to offer free scan online. This was a big help for people that are frequently using a computer mostly for their personal use, meaning it is not attached to a network and usesrepparttar 143277 Internet only from time to time. Now, they don’t have to spend a lot of money to buy antivirus software that will be used very rarely.

Most of these antivirus programs have to be bought in order for you to use them at their full capacity. Also you haverepparttar 143278 option to test a so called “free trial version”. These trial versions include all or most ofrepparttar 143279 software’s features, and are available to be checked out byrepparttar 143280 user for a short period of time, usually 30 days. After these 30 days,repparttar 143281 program can no longer be used. Other antivirus software producers use another method; they offer a free trial version that you can keep forever. But it is not fully operational, meaning some ofrepparttar 143282 options ofrepparttar 143283 program cannot be used as they are not activated. After you have tried a program and you consider it is fit for your need, then you’ll have to buy it to protect your computer at its full capacity.

Lately, viruses are mostly spread through e-mails because this isrepparttar 143284 most common use ofrepparttar 143285 Internet. Also, e-mail viruses are easier to develop. E-mail viruses make use ofrepparttar 143286 ability of having macros or scripts implanted in word documents, spreadsheets, HTML pages, and are programmed to run whenrepparttar 143287 document is opened. But how does an e-mail virus works? When an e-mail with an infected document or program is received,repparttar 143288 user unknowingly opens a document/program, which in turn executes a code to openrepparttar 143289 e-mail directory and to send a copy of itself as an e-mail attachment to a certain number of addresses. Some ofrepparttar 143290 recipients ofrepparttar 143291 e-mail open its attachment andrepparttar 143292 process repeats itself.

This is whererepparttar 143293 antivirus program comes in. This program is set to check all incoming and outgoing messages and their attachments. If an e-mail is detected to have a document or program infected with a virusrepparttar 143294 program offers several possibilities to deal withrepparttar 143295 threat: deleterepparttar 143296 e-mail, put it in quarantine or try to disinfect it. Most ofrepparttar 143297 times, these choices are left torepparttar 143298 user’s decision. It is up torepparttar 143299 user to setrepparttar 143300 program in such manner to best fit his needs. But not all viruses are coming by e-mail. A few of them use security errors inrepparttar 143301 operating system or your Internet browser to be launched automatically. But if you keep your antivirus and allrepparttar 143302 other programs updated, there will be a small chance of being infected via this route.
