Issue

  • Unknown applications, folders, or icons appear on your PC.
  • Pop-ups appear repeatedly with interface similar to anti-virus software or Microsoft support notifications. You can see warning messages about viruses, vulnerabilities, and system problems inside those windows. The warning windows occasionally show a telephone number to contact for resolving the issue.
  • The PC is working slower than usual.
  • The mouse pointer moves independently, browser or other application windows open by themselves.
  • You receive a lot of spam, often with threats: your computer has been hacked, personal data or browsing history has been copied. You are asked to pay ransom in bitcoins to prevent the data from being published.

Solution

  1. In a Kaspersky application, enable detection of legitimate programs which can be used by cybercriminals. See the guide below.
  2. Get rid of the spam emails. See the guide below.
