I keep getting an error when computer slows. It says no available disk space. I check task manager and plenty of spare RAM and processor capacity. I then check the hard disk and to my amazement there is no space left because of the Trend Micro folder AMSP containing 169GB of data. I reset the computer, check the folder again and find it to contain nearly no data. can you explain or assist? IS this a virus targetting the Trend micro software?
