It's a beautiful Scutigeromorpha (one of the orders of Centipedes). According to this page
in your area we can narrow it down to the family Scutigeridae, which means it is pretty much related to our European species Scutigera coleoptrata
. At least our species is totally harmless to humans - it only seems to have a high "yuk"-factor to some people due to its long legs and high speed
I can hardly imagine that your species would really be "dangerous" - generally they seem to have small fangs (hardly able to penetrate our skin) and not very effective venom (like a bee sting).
How big is this species where you live? Our S. coleoptrata
reaches about 3-4cm body length at most imho (well, Wikipedia
says 50mm - not sure how acurate that is - would consider that abnormally gigantic) - although due to the long legs people tend to think it's bigger
The (huge) tropical Centipedes in the Scolopendromorpha
are more likely to qualify as "dangerous" and can have very unpleasant bites to say the least.
I don't have any proper info on the species that might be expected in Borneo, so I can't suggest any genus/species for ID. The Australian Allothereua maculata
looks somewhat similar though??
