if your computer has a slow disk drive and you are doing a lot of paging (using virtual memory) to switch from one program to another rapidly, then your disk drive will become a performance bottleneck and your computer will seem to have trouble keeping up with your commands. The computer, here, is "thrashing", spending all of it's time trying to keep up. Imagine a person drowning. They are thrashing because they are spending all of their energy doing one thing to stay alive.

When does thrashing occurs?

Thrashing is computer activity that makes little or no progress, usually because memory or other resources have become exhausted or too limited to perform needed operations. When this happens, a pattern typically develops in which a request is made of the operating system by a process or program, the operating system tries to find resources by taking them from some other process, which in turn makes new requests that can't be satisfied. In a virtual storage system (an operating system that manages its logical storage or memory in units called pages), thrashing is a condition in which excessive paging operations are taking place.

How does your PC operating system know that a QQ program is running on your PC?

When a QQ program is running on your PC, the operating system utilizes system resources such as memory, CPU usage, and network activity to track its presence. The operating system maintains a list of currently running processes, which includes the QQ program. This list is constantly updated by the operating system to monitor the status of all active programs, including QQ. Additionally, the operating system may use inter-process communication mechanisms to detect and communicate with the QQ program.
