PC cursor freezes, PC locks up

About a week to a week and a half ago, my computer started freezing up when on the internet or with more than 1 program running. The cursor freezes in place. ctrl/alt/del and it brings up task manager, but will not shut down/restart the computer. I have to totally cut power.

A few days ago I updated Windows (Service Pack 3) and related updates, and of course it loaded tons of c***, and turned things on that I don't need, like networking & messaging.
My processes list is a mile long now.

A google search brought me to the MajorGeeks Malware removal thread. I did all the installations requested, and am attaching the log files.

I could not disable AVG Free 7.5, so totally uninstalled before running combofix. I downloaded Avira Antivir from your site and that is the only thing I have done since these logs were run.

After these are reviewed, I'd like to know if there is a guide somewhere that tells me all the unneeded things/files/programs I can safely delete/disable in order to regain some speed and memory from our sluggish PC.

Thank you SOOO much.

 

Here is the Malware Bytes log.

 

Thank you for your answer. We have been out of town. I'll post the event logs in 'Software'.
