Quite accidentally clicked on the sponsored link, and then my Opera browser opened page, which immediately closed the browser.
Almost immediately I began to notice in the pages of a completely different sites, sponsored links appear, from which redirects to the Landing Pages or Aliexpress.
These spurious links already tortured, ESET antivirus does not react, dr.Web Curelt! also did not notice anything. Can someone with a similar problem infected browser, please help practical advice.
