[Chris Wright]"1. how did you format it? you can install windows again and it won't delete malware unless you format the partition itself.
Yup. I purged everything, hoping that I could start anew.
[Chris Wright] 2. you probably have render multiple frames turned on in prefs
I have no idea if that was the reason why it worked before but I doubt it because I just tried it a while ago it's still slow (I even received a RAM error saying that I need more RAM even though I successfully rendered everything before the format ((even compositions in 1920x20000)))
