I received a call at 11:20PM last night!!!!!  I was already in bed and asleep.  The caller was a female with what sounded like a German accent.  I had difficulty understanding her but she was representing herself as someone with Windows and asked about a problem on my computer.  I have received several calls of this nature in the past and they're trying to get us to give them access to our computers to "fix" a problem.   I shouted at this caller that it was 11:30 at night and don't call me again and then hung up!    I hate these scammers.  Caller ID said "Name Unavailable."
