Hello,
Please make sure that you have activated the resident protection of Spybot - Search & Destroy.
That's the way to activate it: run Spybot-S&D, switch to the "Advanced mode" via the menu bar item "Mode" --> hit "YES" --> select "Tools" in the navigation bar on the left --> "Resident" and there you can tick the checkboxes in front of the two tools.
Please also immunize your system with Spybot.
Make also sure that your antivirus protection is working and up to date.
Best regards
Sandra
Team Spybot
