Help Bloatware Apps/ Malware?

Hello,
My sister has a Starmobile Jump HD (Pinoy Brand).
These apps keeps installing by itself.

I did NOT install any of these apps, neither did she. Factory Reset does nothing, all of these apps keeps reinstalling. There is no SD Card inserted and I did not root this device btw (maybe it rooted itself?).

Is there anything I could do besides reflashing the device? I've been trying to fix this phone since yesterday.
Thanks in advance!

So to be clear: these apps were not on it when it was first bought and used, and only recently started appearing? And they reinstall after a reset, i.e. a reset removes them and then they are reinstalled, as opposed to the reset simply not removing them in the first place (if they are installed to /system then a reset won't remove them at all).

If those 2 statements are correct then it's possible she's installed something that contained a rootkit malware (i.e. is able to gain root privileges and install itself to /system, where it's immune to a reset) and that is installing these other apps. If you could identify that and were to root the device you could remove it yourself, but reflashing the device would be the simplest way of dealing with something like that.

Note that android doesn't root itself, and cannot become infected without some action on the user's part. The commonest way these things happen is via a trojan, i.e. the malware is hidden inside some other app that the user installs. So if this is a rootkit malware then you need to be careful where you install apps from so you don't end up reinstalling it after a reflash. I've never heard of one of these in the Play Store, but sites that offer paid apps for free are full of malware, and fake warning messages fed as ads when browsing ("virus detected, click here to fix" sort of crap) are likely to be malware installers.
