Wipe command deletes Avast Anti-theft too?

I managed to contact my stolen phone and execute Wipe command. After that I dont get any contact from the phone. Do you know if Wipe deletes Anti-Theft too?

I am asking if anti-thieft app itself survives data wipe. Because from that point I cant track my stolen phone.

Read the article, especially point 4.

I did it but the answer is unclear. Does it wipe the anti-thieft application too making phone lost forever? Yes or No?

The answer is very clear :

4. Log in to your My Avast account from a PC to wipe your phone. This will delete and overwrite all of your personal data.
It clearly says what will be wiped.
