Some malware remaining after standard procedure

I'm trying to clean up my mother's computer because it had a whole mess of malware on it. I don't know how long it has been infected for because I haven't lived with her recently. She suspects it got on there this spring/summer when my cousin downloaded a game he plays.

Before I did the standard procedure, I looked at the add-ons/extensions in Firefox, Chrome and IE and the unfamiliar programs in control panel. I found the following things that googling suggested to be malware:

Hotbar
Browse to Save
Blinkx beat
White Smoke
Oberon game toolbar
search.conduit
Codec-V
Conduit/mixiDJ
Snap.do
DomaIQ
QuickShare
QuickDrag
Software Version Updater (apparently related to White Smoke)
Search Protect by Conduit
White Smoke New Toolbar

I followed the standard procedure for malware removal (logs are attached) and it seemed to clear some things but the following remain:

Blinkx beat
Snap.do
QuickShare

Snap.do is not listed in control panel, but it keeps being reset as the default search engine/home page for Firefox and Chrome. My sister has told me that she's tried to get rid of Snap.do some other way before.


The AV used on this computer is AVG 2013 Free, the OS is Windows 7.

Thanks for your help!

 

Everything seems to be the same as it was before I did hitman the second time.

I deleted everything except for MGtools (it thought it was a trojan). Of course, when I scanned after deleting and rebooting I forgot to uncheck MGtools and it deleted it. XD

Also, if hitman is just a 30 day free trial, then will I be able to use it again in the future? (After the 30 days are up)

 

Three of the things I suspect are malware are still on the computer.

Blinkx beat and Quick Share might not be malware, when I search on google I get mixed results on whether or not they are. I don't think they were installed intentionally but it's possible they were accidentally installed with another program. They're both listed under Programs and Features in Control Panel so I could try uninstalling them through there.

Snap.do is the big problem though. It doesn't seem to be affecting Chrome anymore and it was never on Internet Explorer, but it's still on Firefox. It sets http://search.snapdo.com/?st=nt&q= as the homepage and default search engine, and even if I reset to google.ca next time I restart the computer Snap.do is back. It isn't listed as an add-on in firefox.

 

Sorry about the reply - I was too late to edit my last one.

I tried resetting the firefox homepage to google again and it hasn't reverted to snap.do yet so I think Hitman did work. Looks like snap.do is gone!

 

A couple hours after my last message snap.do was back on firefox. I reinstalled firefox and haven't seen snap.do since but I ran the Junkware Removal tool to be sure as you said.

Thanks again!
