Avast18.8 acting oddly

Well, word meaning varies on people… in any case, “support” is ended already.

End of support for Windows XP/Vista

I believe these are just webpages implanted into GUI, so they didn’t modify programs but webpages.

Also, your screenshot shows Windows Embedded Standard… it’s technically a variant of XP, but I don’t think it’s not officially supported by Avast.

I don’t think so unfortunately…

Well, no news for fix… I got following response:

the vps update package is Instup compatible. There is no such functionality (now) for Icarus.

So, it means it won’t work from now on. They also stated that they might reconsider it if there is enough reason or mass demand for it.
