Virus overtaking laptop/getting worse each day need help asap!

my husband had a window to mini clip games opened and we believe our daughter clicked on one of their websites by accident while we were in the other room and some how got a virus on his laptop and now the virus has shut him out where he can only operate in safe mode...and he also gets errors when he can get in but we cant get into the laptop the regular way there is just a black screen but he can get in safe mode but we cant install the virus programs like avg once he's in we were lucky to get the tgs exe it was rejecting it at first to even recognize that that we can use the scan disk but somehow he got through to open it up and get the info for you
we are sending you this message from my account i'm his wife and we put tsg sysinfo on a sd card and got this on his laptop in safe mode:
