I have noticed lately that according to Task manager my hard drive is reaching 98% and 100% and remaining at this level until completion of most tasks, the size of the HD is 750GB with 120GB used so plenty of space, upon opening windows defender one file was quarantined on the 8/10/15 (TrojanClicker:ASX/Wimad.gen!H) however the problem is only about 2 weeks old. Can anybody suggest a cause and possibly a remedy Thank you.
