This can be caused my many different things such as low RAM is installed in your computer you can decide to get more RAM.
HHD is full and is not defragged maybe clean up a little bit or defrag it.
Too many programs a running at the same time so close some you don't need.
Clean out the dusk in the computer? it gather heat then the computer obviously don't want to over heat itself so it will slow down.
Do you have a old computer? if do, you should decide to get a new one, because old computer is likely to be more worn out and cannot keep up with new software
Worse case is you have a virus, get an anti-virus and have a good scan.
Hope it helps

It could be lagging because Your PC doesn't have a good enough Video Chip or even you PC doesn't have enough RAM to do much.
get a faster internet and/or get anew PC
It should be able too.
Norton should be able to remove it from your pc.
To prevent damage in your devices and in the cable wires.
Get a better graphics driver or buy a new PC. If you have a bad video driver then install a new one!
If its made for pc then yes, but it depends if you have the basic requirements. It works on windows 7 for me so it should work on yours too.
I'd get it on PC just because it will be so much easier to play with a mouse and keyboard.
12 hours :D
It depends on what you are going to do with it. If you need to store lots of information, you should get at least 30 gigabytes. Games and movies require lots of memory too.
