Is anyone else having their browser hijacked to a site something like www.asnews.sg when they sign and first click on a PC change or is it just a local issue to me? Thanks.
If you've got the one that won't let you close the page or the browser but instead puts some advertising up. Do not click any of the buttons. Easiest fix is, while the "bad" web page is visible, un plug the network cable or turn off wifi, then use task manager to close Edge or IE. Then restart Edge/IE and it will fail to load any web site. Close Edge/IE and then re-enable your network. Restart Edge/IE and the problem should be resolved.
A lot of this sort of thing isn't quite a traditional 'virus'. In addition to my regular anti-virus software, I also run Malwarebytes. www.malwarebytes.org It tends to pick up things that the regular anti-virus software doesn't. I'm generally against capital punishment, but I'd happily flick the switch on people that write this sort of software. It's annoying when it's your home computer, but in a small business it's very easy to loose days or weeks to something like this just because you visited the wrong website.
What Peter said. Stuff that happens in your browser is generally at a different level to what traditional antivirus stuff picks up. AV software looks at file-system level stuff and possibly a bit of network related stuff (eg inbound emails). Doesn't typically look at what's happening in your browser.
I was just in Adelaide using another computer. The same thing happened to me a couple of times in 2 weeks. It wasn't regular, so I don't suspect malware. Could be a problem with AdSense? https://techstuffer.com/is-adsense-ads-hijacking-back/ @Simon Hampel Because I wasn't used to the computer and the trackpad was overly sensitive, I can't confirm if I clicked on an ad accidentally, which took me to asnews or if the site randomly redirected there.
Thanks for the info @Perthguy - there does seem to be some reports around about adsense hijacking (Flash based adverts including code to redirect the entire page - which they aren't supposed to do) relating to that website. Just in case, I've blocked a few Ad Networks associated with that domain and explicitly blocked adverts from that domain as well. It may take a day or so for the blocks to start being enforced ... but please do let me know if it happens again.
