I installed Avast Home (free edition) the moment I purchased this new Acer laptop, running Windows 7.
In one day I went from 20% of the hard drive (c:/) to full!
I definitely have a virus/malware something that avast did not protect me from.
How can I create a CD that scans and fixes during the boot?

Welcome to the forums, KitsapLady 
Have you tried a boot time scan with avast?
Also, that Acer probably came with a pre-installed av program. Did you remove it and how was it removed?
I have a brain injured aggressive post transplant grandson staying with me…
Please forgive me me for the reply…
I’m new to AVAST, and I don’t see an option for a boot time scan. Can you tell me where to find it?
I have not reformatted my new computer, I have made the installation CD’s. I’d really rather not reformat.
I have already used Malwarebytes, that was the first program I downloaded before I came here.
Wow… Hirens Boot CD’s… I remember that from the old days! I’ll have to look at that page and see their is if a boot cd for me!
