First thing to note: S60v3 is not a former 2 S60 platform, their security classification is not a level, or you can say that they are completely different in the two systems. We use S60v3 platform of a cell phone to another view, in order to adapt to the new rules of the game. The first 2 Platform installation file format is the sis format, it's compiled and content can be easily modified. And the system of preparedness to it almost zero. Even if it means that there are destructive code execution will continue implementation of the system. But S60v3 platform, sis only converted to a file without Sign, direct use of the sis is not directly run by the installation. From the user's perspective, you need to Sign a certificate of the sis (remember, this is not to say that previous S60 platform installation files using simple certificate Sign can run on version 3, because the essence of sis which is totally different, architecture is not common, you can view the top navigation posts), here's certificate, roughly divided into two kinds, one kind is the free certificate, free certificate permission extremely low, but extensive high, now repackaged with this, but this only applies to non-protected UID is free software ... Note that the free software is very low! (Incidentally, many from S60 2nd Edition come before one, complained that the 3rd Edition of the Manager, such as Y-broswer and SExplorer **, many file access is not a better Fileman and SeleQ ... This argument is groundless, mainly because there is no clear distinction between, first, the new platform, sis, sisx and if you have Fileman and SeleQ, and is free software, then I guarantee that you will call them a few words. A file manager functionality while the decision by the program itself, but this is just a "capacity", available at sisx inside, have the ability not to have the power to, is the ability to access the folder, this mainly by certificate level determines the permissions of the certificate, charges than the free one, but there is currently no software vendor fees of file manager certificate, so don't use previously on the S60 platform's perspective 3rd Edition) 【 virus on 】:
And then back to the topic, as the sis file itself is not security, virus is very easy to write and succeed in the old platform installed, result in the previous wave of mobile phone virus appears, but the real virus must have self replication capabilities, and dissemination of destruction capacity, strictly speaking, is not in the S60 real virus, can only be described as "potential virus", but this article in order to facilitate the combination and habits, or that the virus now Nokia aware of the problem, antivirus software does not eliminate the phenomenon of nature, on the basis of the sis, sisx file format was introduced (in fact there are many factors, such as to prevent cracking, maintain copyright and so on) this is no longer a previous sisx sis file, he in the packaged when will filter out unsafe code, is to be on the machine have damaging code, if the program is free with a general-purpose, then he certificate packaged in after the restart and not be as random as 2 version before start and continue to attack, because free certificate is not random start permissions, this in the "incoming call" and "TY screensaver" there has been realized and free certificate of software and do not have permission to modify the system folder, as to undermine the system file?? Don't even think about some users ask, then get into random start similar "incoming call" virus not just miserable?? Don't forget, here though to slightly advanced certificate, but the certificate is only to install a phone IMEI, the world would not be so clever thing, just in the IMEI of machine??! Also some users would ask, as long as a charge certificate is not made it yet?? Yes, indeed as long as there is a high-privilege can be devastating but have a question to the attention of the high authority of the certificate is a certificate, must be charged to the Symbian application certifications, and is made up of the program before you apply for, does Symbian will give a virus software send highly privileged certificate?? There are also charges for certificate of ... "virus" software vendor, every year to pay for your software, Ah ... You can reach 350 USD/year!! Prior application Sign to 240 ~ 400 euros (thanks the3sky) well, simply put, the virus may not appear on the S60 platform is now available for the antivirus software, you can delete all, for me, those are just a waste of memory of things … No need to worry, there's no need to surf the net for antivirus software, because sisx itself is "antivirus software"
【 The virus of phenomena and problems 】:
Many people in a computer virus, the scan phone storage card and found a virus, that virus transmitted to the card, so the judge had first cell phone viruses, computer viruses of program code in the phone's S60 smart system is not universal .... so, cell phones are going to do??? The virus is "stay" in it, the system simply ignore it ... may users may ask: why card has a virus??? Obviously I was out with computer kill Ah?? You are in the cards connected to the computer, the computer virus infects a machine inside the file, such as S60 3rd Edition onto new executable exe class, many viruses can infect exe files or viruses hidden on the card, so we searched out viruses ... told above, the virus cannot be performed on the machine ... Can infect exe files, it will use this software does not appear to be viruses?? In S60 3rd Edition, the exe is very sensitive, we know that many Chinese software is covered on the rsc file for localization, but if you modify a good coverage of the exe on the card, is no longer using the exe program representatives, as the exe in machine has a Hash, so long as what is modified, the system must know that you are not running the solution: use the computer once the card kill poison, then from the antivirus results to know which software is interested of exe
Stained, then machine replace the phone software, covering infected exe file.【 Author conclusion 】:
Now on S60 3rd Edition is not a virus, unless you wait for the certificate and the security system be cracked, but so easy yet?? 3rd Edition but even out, security than computer also sensitive, antivirus software quickly removed from the machine! don't waste memory resources ... We also do not need to be afraid of the phone is infected with a virus.
