(KANSAS CITY STAR) — It’s time to get (your computer) tested if you’ve used the popular porn site Pornhub in the past year, because your computer may have been infected with a virus.

Cybsersecurity firm Proofpoint announced this month that it had uncovered a malicious program that had been lurking in Pornhub’s advertising network. The virus, called Kovter, had been routinely attacking visitors for more than a year, the researchers found.

Here’s how users would get the virus: After visiting the site, a new tab would sometimes pop up saying there was a “critical update” for whichever web browser the viewer was using. If the user clicked the update button, the virus would be downloaded to the computer, where it would then track users’ personal information and browsing habits.
