I am using Win 10 and Chrome browser and using the Windows default settings which I believe includes Defender Anti Virus. The Chrome browser has picked up some malware. When I click on a link in Google search results, it gets redirected to some other site. I then press the Back key and click link again, and it works OK... Does not seem to happen when I launch IE browser... What is the best way to get rid of this?Mostly the latter, although when Microsoft merged their consumer OS with their professional OS they were a little sloppy and left quite a few holes that have since been closed up. At this point Windows is about as secure as any other OS, but due to its prevalence in large commercial enterprises it is still heavily targeted. Although the popular targets for malware these days are mobile devices (especially web browsers) and cloud services.
