It was supposed to be after Emsisoft installed BDTS and it was...But however, I made a return to AVG IS. Why ? The reason is one. Less resource consumption. I have nothing against Bitdefender. It is a very good choice. But working on a laptop (such as browsing the Internet) is a bit slow. It is faster than Emsisoft but still causes slowdowns.
Therefore, the choice (long planned) fell on AVG.
Protection - very good.
I finally have the luxury of browsing with security.
AVG IS consumes much less memory and is very good
