How long did you wait for the startup? I usually go for a little walk or stretch myself a bit if it takes longer, but it has never failed to boot for me since the last two years at least.
Personally, I can’t remember having problems at startup with Avast and I’ve just switched from CF 5 to 6 on my W7SP1x64 laptop in the last couple of weeks.
I’d suggest the following:
- be patient when it happens or get a SSD if you don’t have one
- try clean install of both Avast and Comodo
- check S.M.A.R.T with CrystalDiskInfo and post a screen shot showing every raw value meaning expanding the window
- if it comes to the worst switch either AV or FW or try a complete clean install of Windows and everything
Also, listing your computer specs like
- CPU
- MB
- RAM
- GPU (especially with the GPU driver version)
- PSU
- HDD/SSD
might help in debugging the issue.
