Since am really paranoid i use the most recent hack and trusted hack, for about 5-6 hours after release. i put the .exe on my usb so theres no files on my pc. There also ways to hide your cheats better so you have a better chance not getting vac banned, am not telling you the programmes i use but am sure u can find something with a googles search. Public cheats do last about 1-2 days i wouldnt go over that tbh, private cheats obvly last a lot longer since theres not as many people using them.
