Do you have anti-virus software installed? If not, install AVG and run a scan, also install Malwarebytes and run that scan. You can then uninstall Malwarebytes and leave AVG running. If the system won't let you install the programs, which some viruses do, download a rescue boot disk from an anti-virus vendor and boot off that to run a scan.
