Besides im so afraid to delete something by midtake with itunes
What will be lost if ill delete the cache?
I asume the memory is full with games
They force download 300 mb but charge for the full game
Or they have try first chepters free light version always?
I cant see disc usage in here

I'm not quite clear what the issue is here. The cache on the iPad is typically just the cache of webpages that the iPad holds. If your main computer has viruses then, once it's clear, all should be OK again. The iPad cannot get a virus from a PC so there's no danger of 'infecting' the iPad by synchronising with the PC.

How is that ipad cant get viruses from pc ?
The cache has the history and cookies or the webpages themselves, hiw can i know if the cache is what makes my ipad say it has no memory free and delet stuff
