Hi,
I would like to know where one can buy original engineering softwares and antivirus in kl or bangi. I am looking forward to buy the latest version of Autocad or SOLIDWORKS or Catia. Are the original ones expensive? I am an engineer not a student. I am looking to buy one with a license term of 3 years.

Can someone pls tell me too why in Lazada and shopee these softwares cost just between rm15 to rm30 each... They are pirated right? Is it reliable to buy and use them?
