My system has slowed way down after the last update as well and this is a nice PC but I cant play any games on it right now. Looking at my Task Manager Trend is eating up 80% of my disk usage, something isn't right
Such as: Norton 360 (all version), McAfee SiteAdvisor, AVG Anti-Malware etc.
Also, the slow performance could be due to background internet traffic from programs that you've installed unknowingly. These programs, commonly called potentially unwanted applications (PUA), are typically bundled with other freeware, and installed as an option most people do not uncheck during installation. Please try the following online solution doc to check and remove any PUAs on your computer: Uninstalling Potentially Unwanted Application (PUA)
Some common PUAs are: SlimCleaner Plus, Pokki Start Menu, Inbox Toolbar, MySearch, Coupon Printer for Windows, Image Resizer for Windows, and many others.
After the above steps, if you are not using the latest version of Maximum Security (ver. 11.0), we would like to suggest that you reinstall Trend Micro Security to the latest version to reset the program and patterns. You can refer to the link below for detailed steps: Reinstalling the latest version of Trend Micro Security program
It's quite a few steps to perform, but please do let us know if it solves your high disk usage and slow performance issue. If the problems persist, please let us know what kind of games are you playing and a description or picture of the screen for this issue would also be very helpful. Thank you.
