[newbe here needs some help-- quarantine to many files!]

I have been using Malware-bytes for a :long" time with no ill effects. Until now.

I was cleaning out some files for a friend. MB scanned and showed some bad files. I clked to quarantine  them and went to heat up my coffee. Came back and it was on 1,000 and xxx number file. OOOPS. I knew I had a problem.  Long story short I should have never rebooted the box because after I couldn't log in as a Admin. Just a Guest. Can't change anything as Guest!  SCREWED!

 I got past the log on problem today. I started this easy small job on Sat.   I can now get in to the PC and fix some things.

Question:  Can I UN-quarantine  those files some how?  I am afraid to reboot because I may not be able to log back on again.   I am thinking of doing a system restore. Even if I get the files back I may.  Looking forward to hearing from someone. I could use the help. 

Windows 7 Home Premium,  Lenovo Z565 PC.  Sorry but I can not start Malwarebytes right now! Just tried to get ver #, probably a few yrs old version. still need info though.

Thanks, Brian
