If you missclick the download button on the download page for hwinfo you download a virus instead.

Ads are placed by Google, so if you were redirected to a malicious site, it should be reported to Google. This could happen on any other site.
If you provide more details like the link, I will investigate that and report.
I dont know that sounds like an excuse to me. You and others decide exactly where the add is, purposly placed so that people click it. sure yo do not control the content but you certainly control exact location of ads. and you know what kinda ads you have. you know already is the basic assumption i have from this exhance of words but also that one of you might actually be devs of the softwares on the ads. idk thats just a conspiracy theory though. but it makes sense if that is the case.
