^ Like the title says and the screenshot below demonstrates. Avast version is .2322 and virus definitions update is 180113-0 (which judging by the numbering is from today). Was working on my laptop this morning when an Avast alert popped up.
I removed Avast on my desktop/main PC in order to get the Meltdown patch, but left it on my laptop as I don't use it that often and figured the Meltdown difficulties would be sorted eventually. Well...so much for that, apparently. My laptop tried to pull down KB4056892 along with a Malicious Software Removal Tool update (KB890830), only for Avast to interfere by shoving one of the update files into its Virus Chest. I restored it, but the updates are still stuck at "Installing - 0%," presumably because of this. Charming.
While I'm aware that false positives do happen, this is really beyond the pale IMHO. I think I'm done with Avast.
