Hello Zach, thank you for the welcome,
I downloaded the member version of the zip file from the GreenSock web site. I played around wit the scripts and making some experiments. After a wile I looked in the directory where I unzipped the package to check out the plugins to see what they do and notice that the last modified year of the files was 1985.
I deleted them and unzipped them again, the antivirus didn't pop up when I scanned the PC in search of threats. The files are up to date now, I guess I have a rootkit in my machine, because I played with the scripts again for the past hour and don't notice a thing.
Please forgive me for posting this on the forums, but it's a little bit strange that the rootkit messed up only with the GSAP scripts and live the rest of more then 4TB of archives I have on my drives
Guess I have to format my HDD and reinstall windows, Now a days if someone wants to infect your PC can do it very easily and I notice that the antivirus doesn't prevent the infection and less on a windows machine.
Sorry for the inconvenience, by the way I love GreenSock, im a Front End graphic designer how is learning how to program, thank you.
