PUP.Optional.FrostwireTB.A, PUP.Optional.OpenCandy, Backdoor0.Access, Trojan.Medfos, and others found on my PC

Yesterday, I ran a Malwarebytes Custom Scan after noticing some strange things on my PC.  It seemed slower than usual, as well as opening 2 tabs at once whenever I tried to open a new tab after a short delay.  To sum up, the computer seemed to studder with every action I took.  I first did a virus scan using Avast! free antivirus, thorough scan, which turned up nothing.  Then I downloaded the latest version of Malwarebytes and did a Custom Scan.  What turned up were many instances of PUPs and other nasties:

 

PUP.Optional.FrostwireTB.A

PUP.Optional.OpenCandy

Backdoor0.Access

Trojan.Medfos

 

FYI, I don't know much about computers.  But I Google-searched these names and determined they were not the sort of thing one wants to find on their PC.  I quarantined, and later deleted, all instances of these items.  I did another Custom Scan today, and it revealed no instances of any malware.  The "studder" also seems to be gone as well.

 

Basically, I was wondering what to do next.  According to Malwarebytes, nothing more is turning up in the scans.  Am I free from this malware?  Would it be safe to do something such as buying something online with this PC or entering personal information?  Or is there any other action I need to take?

 

Any help would be appreciated.
