Hi I am new to posting here. I have an HTC desire z and recently I have noticed the number of pictures in my downloads folder in the gallery going up and up. I actually have 14 pictures in there, but it is repeatedly downloading 3 thumbnail icons from somewhere: twitter, bms and linked in icons. (All of which i don't use). These then repeat and repeat. I deleted them all last week and yesterday i was back up to 2800 downloads all these 3 icons. Again i manually deleted them this morning and i am already back up to nearly a hundred. I am worried this is something malicious and am also worried about data charges. Can anyone help?
