Uninstalled system applications appear after reboot on HTC Desire X

I have tried a lot of things which mentioned in different forums such as:

• delete using root ES File Explorer.


• delete apk files from /system/app.


• clear Dalvik cache after uninstall (manually removing /data/dalvik-cache and /cache/dalvik-cache and using CWM recovery.


• all mentioned earlier together several times.


• Even reinstall ROM wiping data/factory reset and clearing Dalvik cache using recovery.

But no result. And I get something like this on startup if I clear Dalvik
cache:

So there is a location from where OS gets these apps, isn't it? How can I get rid of these redundant apps?

Update:

Here a link where I downloaded ROM: https://forum.xda-developers.com/showthread.php?t=2249760
