I know a lot of SC:BW programs can be false positives for virus's, but I just wanna be sure this is the case again. I just downloaded Dat Edit from here http://www.staredit.net/topic/17533/ and my PC thinks it's a virus, I just gotta double check with you guys before the go ahead.

Also been trying to find links to the other vital EUD programs, EUD Editer 1/2 links are down as well as EUD Draft. Please help if you can someone, thanks!

Datedit should be fine, but I think most people suggest PyDat nowadays.

Do those programs work with SC:Remastered ?

Sure, the .dat files are not changed in any way. Only sfxdata.dat seems to be supplanted by rez\sfx.json.
