There is no "freeze". It is a block.

A application start without AV would look something like this.
1. User requests app start
2. Windows itself calls a low level method called X
3. X returns after doing something
4. Other stuff happens in windows
5. App starts

With AV in place the above process becomes the following instead.
1. User requests app start
2. Windows itself calls a low level method called X
a. Call to AV is made
b. AV does stuf
c. AV displays dialog
d. (other stuff.)
3. X returns after doing something
4. Other stuff happens in windows
5. App starts

In the above c blocks waiting on the user. Since it blocks 2 blocks. Since 2 blocks the entire process blocks.

The AV accomplishes this by hooking into windows low level functionality. AV apps probably use quite a few different low level API hooks but in terms of this question only the specific one is called "File System Filter Drivers".
