I will share what I know.

"[T]here are lot of svchost.exes running" is normal and from the report, the source of the svchost.exe in each instance seems legitimate.

There are five programs, two or three of which are security-flawed, outdated.

Firefox is now at 15.0.1. Isn't that the purpose of the Maintenance Service?

VLC is now at 2.0.3. (Cosmetic and functional changes)

Java, even with the auto updater(!), should be at 7-7.

Adobe Reader is at version X?

Adobe Flash didn't list the version, but I suspect, with the numerous recent changes, that also is not at 11.4.4.

As to why your "svchost and explorer were using max cpu", were previously installed 3rd-party security software cleared and cleaned out before installing Avast? Remnants in the wrong place, while not seen as threats, could wreak havoc.
