1, it just hangs on a black screen before asking me to log in.
2,the virus was something acting as an anti-virus asking me to pay to download the program to get rid of "viruses it found on my computer".
3,After using system restore it worked fine for a few hours, but then when I tried to turn it back on the same problem came back.see point 1 above.
