My internet suddenly disconnected, scratched head, did checks through windows troubleshooter, none found. Then I found that the network card has been disabled by windows, it would not let me repair install/new/delete install, had to go through safe mode to delete drivers, rebooted, reinstalled drivers problem fixed. No idea why.
did that no joy, just did similar again, but uninstalling virtual box seemed to fix problem, no idea why, but it seemed to became to dominant internet connection, even though nothing but the base program is installed.
use malwarebytes/superANTIspyware and try to clean, could be something trying to infect/use your internet as a host for a virus
I wasn't even downloading at the time, just browsing this forum when it happened, well so far no a problem since I uninstalled vb. Have full done full scans with a number of proggys, nothing found, as I said problem seems fixed.
