If you have a virus or Trojan present on your PC and it has been detected by your anti-virus software, you should follow the instructions to successfully remove it and run a full anti-virus scan afterwards to ensure your machine is clean. If you think you may have a virus or Trojan and do not have anti-virus software, use a specialist tool (like Windows Malicious Software Removal Tool) to detect it and remove it. Then be sure to install and use anti-virus software. If after following the advice above you still have problems then contact your PC supplier.
