Sorry, to say but the problem is SW you need to bring your phone to factory settings and re-install all your applications as I did, no big deal.
Well, at least this is what I found:
The Malware resides is in the Flash Memory Card. How it got there? Well, .. since I did not access the web with this phone at least that I am aware of, has to be thru. one of the applications I installed. Malware worked its way to the Media Player making un-operable some of he functions of the phone including the joystick, a bit every time like 5 months?.
First I reseted my phone to factory setting.
The player worked once and the problem came back right away!
Then I re-formatted my 1GB kingstone flash card this way:
E:\>format e: (*while out of the phone!!!*)
bla, bla ....
Format cannot run because the volume is in use by another process. Format may run if the volume is dismounted first. (note the flash card was out of the phone)
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID. (this crap you don't see it is hidding)
Would you like to force a dismount on this volume? y
volume dismounted. All opened handles to this volume are now invalid.
Initializing the File Allocation Table ..........
volume label <11 characters, ENTER for none>?
Invalid media or Track 0 bad -disk unusable. (So, my flash was damaged, I replaced with another 2GB Kingstone, sofar it is OK, 3 days now)
Note: the Malware file(s) are hiding some where in the flash card, all what you see is your files in there.
Nice would be to have an application that will detect the crap and remove it.
After reading some post on the subject I can tell that the flash card size and made does not matter.
Just to be safe I reseted the phone again to factory settings.
Now, after installing a new 2GB flash card with all my sounds ... No problems any more, my phone start functions as it did once!
Be aware, after loading your flash card all its contents will be wipped out while listen to music, in my case.
Don't panic! just reinstall your files into the flash and your done!
I think my problem started with the "smarturke" scientific calculator crap, I deleted that program but by them it was late.
