Chrome Infected withallsearchapp

[etsdca]

The default page on my Chrome is http://proxy.allsearchapp.com and I cannot remove it, I'm pretty sure Chrome is infected. I read the post 'BEFORE YOU POST' but I am very nervous before running any software on my PC especially knowing that it's already infected. Please patiently walk me through what steps I need to do to remove allsearchapp malware. I got from the 'BEFORE YOU POST' is to run ERUNT to backup registry and run DDS to get a log.

Thanks
