I think my computer has a virus. I get popups in the toolbar stating I am low on disk space for C drive. I took over 50 GB of photos off yesterday and moved them to a external hard drive and again today get the same message and the C drive states I only have 43.5 mb available. I have norton and did a full scan and found nothing. Downloaded SuperAntispyware and started the free trial for professional. It has been scanning for 23 hours and is still not complete. I have used the free version for months in the past and never had this problem. Can anyone help? Thank you.!
