So, I won’t use the language I want to here in my first post but really, this software is sucking up my processing time. Everything I do since PURCHASING and loading this software is slow or even inexorably delayed! There is no other reason than this software. I wish I could get a refund and go back to the free version which caused NO problems whatsoever. I certainly will NOT renew this software pacake. 
- Which version/build of Avast Premium…?
- OS…? (32/64 Bit…? - which SP/Build…?)
- Other security related software installed…?
- Which AV(s) did you use before Avast…?
After latest update avast is taking 100% of my cpu only way to use my machine is to uninstall Avast never had this problem before
