We’ve been dealing with this incredibly frustrating problem for more than 2 months. I’ve tried all suggestions and reloaded several apps including Trend, Foxfire and Irfanview with no improvement.
When not connected to the internet but using our home LAN, everything is fine. After connecting to the internet and doing a search, everything slows to a snails pace. When either we disable Trend or disconnect from the internet, full speed is restored in all apps. Then, there is a brief reset when reconnecting to the Internet - Foxfire loads instantly until a search s performed.
An example of the impact of this problem is Irfanview which normally loads in the blink of an eye. The Trend-Internet caused problem slows that to over 1 full minute to load the app and nearly a minute to bring up each image. Results are similar for all apps including MS Office. Equipment involved are Win 10, Dell high end laptop and a desktop.
