I updated my Windows 8 laptop to Windows 8.1 on 1/22/2014. Secunia reported that all apps were then up to date, including Chrome. I ran Chrome and found it was v.31. I downloaded and installed Chrome 32 and noticed there were two Chrome icons. A little surfing told me that Chrome always leaves the old version in place. I deleted the old one. I then ran Malwarebytes and was pleased to find nothing. I then ran CCleaner and deleted what it found:
Google Chrome - Internet Cache 49 MB 380 files
Google Chrome -Internet History 740 KB 20 files
Google Chrome - Session 57 KB 2 files
Applications - Adobe Acrobat XI 9 KB 1 files
Applications - Office 2010 6 KB 4 files
Utilities - Windows Defender 125 KB 21 files
Windows - MS Search 3,072 KB 3 files
I then wanted to see how many Restore Points I had created, and discovered that System Restore was turned off! Did CCleaner do that, or does Windows 8.1 come that way?
