On the XP PC at work I keep getting an advert with an arrow which points directly at My Posts. Difficult to avoid but not impossible.
On Vista I don't get the same.
I think these annoying adverts are something we're just going to have to live with. The Microsoft 365 has just elapsed, now we get another.
No matter how much we complain or contribute to endless threads, nothing will get done (despite promises to "look into it") because that's how the forums are funded (no cost to us apart from the inconvenience) so let's get on with life and try as best we can and live with it.
Kaspersky has anti-banner enabled by default and I had to change the settings to even see this ad. It isn't a major problem and I don't understand why you are clicking on the ad instead of My Posts. The page may jump a bit but wait a few seconds.
