Suspected Adware and other problems - Can't Remove

[hphuongan]

Hello,

I'm infected with several viruses, (using Avast free antivirus to scan), but one virus (Win32:SupTap-O [adw]) kept reappearing after my afterward rescans. So I downloaded Malwarebytes, ran it and after that rescanning on both softwares didn't yield any threat any more. I thought problem was solved, but when I was browsing by Chrome, some random ad site reappeared again at random clicks, just like some user with adware issues had described on this forum. Please help me on this, it has been very frustrating for a few hours. 
Addtionally, my computer has been very slow lately, which I thought was due to failure of the hard drive, turns out it is virus all along. Also sometimes when i'm typing the cursor just jumps around randomly, and taskbars and windows would freeze at random with only logging off then on again solving the glitch. I think this is also due to the viruses, but I'm not sure. So how do I remove the aforementioned virus and other problems?
Many thanks in advance.
I attached the log file from FRST, as instructed by the pinned post and the screen cap of my first avast scan
