My Avast! has been screwing up, saying the file system shield isn’t active. The program says a reboot is required, although rebooting did nothing to aid the error. I tried to reinstall the program, but on uninstall it told me that I have to reboot to complete Avast’s last action. When doing a smart scan, it seemed to finish really quick, although I don’t know how long a smart scan should take due to never using it before (it said no virus+malware was detected). No other shields are down.
I use Windows 8.1 64-bit if it is important. I have no other Anti-Virus programs installed, and never had another. I am however running Malwarebytes and SpyBot with Avast!, but that hasn’t troubled me before.
