Yesterday 3 updates failed, these were hydra, virgo and capricorn, tried to run again but with no success. Is this important and should i take other action?
Try rebooting your computer, and also check that there are no Windows Updates waiting to be installed.
If restarting don't help, then try resetting F-Secure's updater by the tool "FSAUA-RESET TOOL".
Download it here: https://www.f-secure.com/en_US/web/home_us/support-tools When downloaded it, rightclick on it, and click on Run as administrator, and check F-Secures updater to see if it works...
