Weird Problem With Sony W960i With Uninstall Options

[w960i_guy]

I have Sony Ericsson w960i phone and I downloaded and installed two apps, Touch dial and Mobiola Webcam. Then my use for them was over and I uninstalled them from the uninstall option of the phone. Now, whenever I boot the phone, just before the welcome scree two "installation pop-ups" comes. One for Touch dial and the other of webcam asking me if I want to install those apps. I am not able to get rid of this problem. It also pops up when I disconnect my phone from the computer (when connected in fast mode)

I also tried saying "yes" so that it will install the app. After pressing yes, it will show the progress bar progressing and then it doesnt give any acknowledgement. Neither do they appear in the menu anywhere.

Please suggest me some methods to overcome this problem
