So i just downloaded Tombraider 1 2 and 3 setup. And clicked on it,and it said my norton removed it. Cause it wasnt't safe. I dont know whats going on,but how will i fix this?

1) The files are perfectly safe.

2) Norton has a tracking mechanism whereby files are sorted by how commonly downloaded they are. If a file hasn't been downloaded much, it's automatically considered to be dangerous. Apparently TR1-3 hasn't been downloaded enough.

3) I suggest investing in a different antivirus. Norton is subpar in a variety of categories.

Ditch Norton and McAfee those two are not very good. Use Microsoft Security Essentials, Bitdefender, or Avast instead.

I second bevinator posts

Just thirding the "ditch Norton" sentiment.

why should he ditch Norton? The gentleman in the shop assured him that Norton is the best and will provide 100% safe internet browsing.
Clearly it is GOG's fault that happen and they should do something about their problem.

Of course it's not safe, you can fall into holes and die! Some have bloody spikes in them! There's friggin' tigers and bears in it, and they ain't happy to see players too! It's a deathtrap really!

Just continuing with the Norton dislike. Personally I consider Norton Anti-virus to itself be a virus. It messes up your system. It asks for your money, and it's generally harder to remove once on your system than your average virus. I've had several computers left unbootable or without the ability to use it's network interface after running the Norton uninstaller.

That said, if you don't want to ditch Norton, it's possible to right click it's icon and disable the AV-protection for 10-15 minutes, that should work.

At work I've made a loginscript users can download and install to their laptops to add and authenticate against shared printers and drives. The .hta script wrapped in a standard InnoSetup installer to easily add a start menu shortcut and uninstaller. Norton tends to eat it if people try to download it. Disabling it for a 5-minute stretch fixes the problem about half the time. The other half of the time Norton will say it's disabled but still be enabled.
