Unable to update anything or download.  Message says hard disk full.  I only use my PC at home and it's only 3 years old.  Should not be full at all.  I bought program, from Advanced Tech Support in mid August to check my PC as IE 11 wouldn't open a lot of the time.

They would come in remotely just before I'd go to bed to ck it out.  They did not close the connection or leave a note so I could. They deleted most of my downloads, some contained .dll    I am a novice but know enough not to delete these. 

I can not update Microsoft Windows, Security Essentials or my Anti-virus program.  I have Kaspersky Pure 3.

Appreciate any help, or Microsoft to remotely look into.
