Browser tabs taking up to 100% of CPU

Hi !

I would need a suggestion what could be the culprit here. I was on a bussines trip and was on a hotel wifi for 2 weeks, after i returned PC started to stall and overheat. I did a whole system check, ran it through few cleaning apps (adwcleaner, emisoft emergency kit, rogue killer, gridinsoft) and indeed found few threats that got cleaned. Now all of them show nothing but CPU is still jacked to 100% during processor easy tasks... for instance playing videos or just watching stock screener.

I even ran it through FRST a few times and get rid of some unknown stuff there but the issue remains. I don't believe that stuff that was running smoothly until recently suddenly starts to stall everything and melts my CPU, but i can't find anything that could be doing this.

I'm attaching FRST and addition files beforehand to make matter quicker

Hi !

There was no need to ZIP the file on my desktop, it is just my tab where i keep track of my runs, thus the weird name 

The log output is here:

Thank you.

Is the CPU usage the same?

Yes, unfortunately no luck.

Best indicator is a stock screener i use, stock market is closed now so there is no active element on the whole page now and CPU si on 100 all the time.

I use mainly chrome, but other browsers spike too (altho not as much, they max out around 60-80 but that is still far from what it should be)

• Press the Windows Key + R at the same time.
• Type msconfig and press Enter
• If you are prompted for an administrator password or for a confirmation, type the password, or provide confirmation
• Click on the Startup tab
• Click Open Task Manager
• Note down each entry listed as Enabled then right click on the item and select Disable (you will need this list during subsequent steps)
• Close the Task Manager windows and you should be back at the System Configuration window
• Click the Services tab
• Click to select the Hide All Microsoft Services check box
• Click Disable All, and then click OK
• Click Apply, then OK
• When you are prompted, click Restart and boot into Normal Mode
• Check your computer performance

• Results?

Tried to disable everything like stated, but aside from disabling a lot of crap that i didn't know i even had still, there was no visible change.

The few pages that pumped CPU, still does.

What i noticed while finicking with it is that Firefox is doing better in general. Chrome is maxing out on almost every page. I also tried to delete every extension in every browser, no change either.

One quirk i noticed was that touchpad (which i never use because i have a dock) is always on after restart, even when i disable it manually. But that's probably nothing because performance don't change when i disable it.

Thank you.

Please Add a new Chrome Profile and test the performance.

Added another account, but still the same result.

Even when more processes use up the CPU, as soon as any is available it pops above 80.

update:

Might have found the culprit... as it turns out, my CPU + chrome was crap all the time, and when "graphical acceleration" is off, it juices the CPU like crazy.

Don't know how did i switch it off, but after turning it on, even the permanent 100% tabs eat only around 20.

*the more you know chime playing*

I think this topic can be closed... but atleast you helped me clear a lot of sleeper stuff eating away resources in background for no reason 

You are welcome, although I didn't contribute much.
