Hi, New User Here. I have just run Avast for my MacBook. Got errors not sure how to proceed. Error 42110 "The file is a decompression bomb." This is a warning. It sounds really dire. What's a decompression bomb?? Also got Error 60 - Operation timed out and Error 42120 ARJ archive is corrupted. I think I will go ahead and delete the corrupted file, but what about the time-out error? Thanks for your e-help, I'm really new at this.
