So, I’ve been having this problem for the last couple of days and I can’t seem to fix it myself. I am usually pretty good at knocking out spyware/malware but this one has me stumped. Avast won’t start with Windows, nor can I start it on it’s own after boot up.
I have attached the requested log files from the sticky in this forum and I want to thank whomever comes to my aid! You guys are saints for helping people out with stuff like this! 
Let me know if Avast starts after the reboot
