It could be the program was infected with a virus, if it is, you have to use some virus cleaner like trendmicro's free online virus scanner. Some free programs happen to be infected, so it's important to do a virus scan at least once a month.
However, if it's not a virus, then you can try a couple of things, try to right-click the program and check properties, in properties, there should be an option called "protect" or something similar to it that prevents the file from being deleted. Make sure it is unchecked.
If that doesn't work, then you probably lack the privileges to uninstall programs. Make sure you are on an administrator account on the computer to try and delete it.
I recently dowloaded a program..and my girlfriend wants mean to delete it..and I go to "ContolPanel-Add/Remove" and I delete the program...which of course is not apparently enough to delete the program..where now I have to find...remains of that progam..I know how to find it..But when I try delete the folder..it says either the disk is full or the folder is 'write protected'
Question#1 Can someone tell me how I can determine whether my disk is full ie.for potential future use..and
#2. How will I go about getting rid of that write protected folder.
Note: I think it is very rude for this to happen..sort of..I download 'free' software..and once in arrives on my computer..it refuses to leave!
