My ISP wanted me to download photogallery and when I did, Norton objected, so I didn't install it.  I'm not sure how useful it would be anyway so I'm quite happy to dump it.
Trouble is I can't find it to get rid of it.  It isn't listed as photogallery.
When it tries to install (I have to cancel 5 times each time I switch on  

 ) it installs as windows installer then photogallery.  
I can find windows installer - but is this for installing 
any new programmes or is it part of this photogallery thing?  I haven't dared delete that in case it's needed.
Can I delete it?  or is it important?  can someone explain 
please?
