I was forced to upgrade to Windows 10 on my Dell PC. Shortly after, Trend Micro starting using a lot of CPU/Memory/Disk. I ran several anti-virus programs (Malware Bytes, etc.) and nothing showed up. I contacted Trend Micro and they told me to upgrade to the 2016 version of Trend Micro, which I did. Still having same problem. They told me to run Trend Micro House call. Nothing. I ran Trend Micro Anti-Threat Toolkit and at 92% of scan completed it said variously there were 1 or 2 problems, and the Anti-Threat Toolkit program shut down (I ran it a few times.) It seems to have been reviewing its own file (attk_far_gui_x64.exe) when it stopped running, on three separate occasions.
Also ran TM's Scan Clean Online program and nothing showed up.
I am lost. Trend Micro has been horrible about responding (and their responses rudely tell me I must respond within 24 or 48 hours! Even on weekends [when they're not open!])
Please advise. Thank you for any assistance!
