Yes, you're right. I am confident that Avast Home can detect all possible ITW script viruses which are already known. I just want to make Avast Home a little bit more powerful to block unknown scripts which may destroy one's system. What I concern most is whether Avast Home can really block bad scripts by using blocker. If yes, then Avast Home is really the most powerful and free antivirus programme in the world. If not, it doesn't matter. Avast Home's detection rate is indeed very good, as tested by many testers.
