I have NVidia GeForce GTx930M, which has only CUDA 5.
CUDA 5 is not so much a problem as it is your low performance graphic cards. So, unless you want to try mining just for learning purposes, it doesn't really pay off.
Al SgMiner files get deleted by antivirus each time I try to download them.
If you know
for sure that you have download a legit virus-free version of SgMiner, make an exclusion in your AntiVirus program by entering the full path to SgMiner to be excluded from scanning. Then it won't be deleted.
