Computer freezes after bootup

Hello,
I have a clients computer that would boot but after logging in would freeze.  I had him boot into safe mode.  With programs he unintentionally downloaded I could tell he would be infected with Malware.

Unfortunately I could not use a system restore point since something wiped out all points before infection.

MSE found and removed Trojan: HTML/BlacoleRef.A.

In Safe Mode (since I still can't run computer in normal mode) ran Rkill, then SAS and MBAM (I know MBAM should be run in normal mode and that was my next step) restarting and running RKill after each scan.  Both SAS and MBAM found plenty of PUPs - how I hate mywebsearch - looked like TV Bar toolbar was a main culprit.  After MBAM ran I tried to restart in Normal Mode...no go.

What would the next step be?  What can be done remotely or do I physically need his computer?

Thank you for your assistance.

Try further troubleshooting using a clean boot

If that does not help try a Repair Install.

Hi jcimarron.  When my client gets back to me I will do a clean boot...if that doesn't help me resolve the issue I will get his computer from him.
Thank you.

Thanks nobus...He informed me yesterday that he has been able to log in with out things freezing before I did a clean boot.  I will run a chkdsk.  Should I do the basic with a elevated command prompt?  sfc /scannow or add something to that?  Thanks again!
