Well, the setup-snakes.exe does interject to other mediums, like the setup-*modname*.exe's as they are the same programs(just different versions of the said program and thus need an update, which is the said interjection )... WeiDU.exe's to be exact, the flagging is off, so the program is secure and without viruses. So it's a false positive.
Two false positives, go figure... try the other 298
WeiDU.exe mods and then understand to turn off the Norton when you install the mods.
And just in case you haven't noticed:
1. The WeiDU.exe .
WeiDU.exe is the program you use to install almost any todays Infinity Engine game mod, BG2 mods included. The WeiDU.exe is actually the installation .exe just renamed as setup-*modname*.exe, so it can take orders from the file called setup-*modname*.tp2. Now there are few bugs this knowledge can sort out, as the WeiDU.exe is still in revision, as new mods need new functions, the versions are updated every now-and-then. This leads to a problem, which has been tried to solve by the auto-update feature that is build in the .exe, but as it is not the most perfect system of them all, so it can cause problems if the proper steps are not taken.
They can almost all be solved by updating all the WeiDU.exe's to the most current version of the WeiDU.exe, which can always be found in here(the Windows Binary archive), you first do the auto update by running one of the setup-*modname*.exe's, and after it has succeeded to update most, you need do the manual update to know what files you need to update manually, and you do that by searching the folder by size, all the up to date setup-*modname*.exe's are about 655Kb's in size(that version is/was v22600), the outdated are smaller, so you delete the old setup-*modname*.exe, and then you copy the new WeiDU.exe from the archive to the game folder and then you re-copy it to the same folder so you have many of them, and then you rename one of the copies as the deleted one so you can run it.
The WeiDU.exe is also moding tool that has it's interface if it's named as WeiDU.exe, and for Windows Vista and Windows 7 users, remember that you have to disable the UAC, read the answer #2, or use it as Administrator, whenever you try to use it cause it won't work without the proper user permissions and file allocations. 
Additionally, the WeiDU.exe renamed as setup-*modname*.exe has many times falsely detected as a virus by many anti-virus software programs. It's a false alarm and if you get that, you have to turn off the anti-virus program so you can install the mod. And usually it's recommended that you turn off the anti-virus program even before you start moding the game at all, as you can then turn it on again after you have finished the mod installations and scan your entire hard drive.
