Videos lag until I move the mouse, 100% maximum frequency [TROJAN MAYBE DETECTED]

[dezork]

I'll be watching a video (youtube, for example), and the video will start to lag-think a slowdown to a few frames per second. Oddly, audio is unaffected, and continues to play as normal. Then I'll move the mouse, and it immediately returns to normal. This happens every few minutes.

I opened Resource Monitor, and it looks like CPU is clocking up to max frequency until I move the mouse, then it returns to normal. CPU utilization doesn't max out, only the frequency of the chip (I guess?).

Any idea what's going on?

Memory utilization seems to be unaffected. I have a Core i7 2600k.

try turning off windows search service, worked for me - run services.msc scroll down to windows search, stop it / disable it

I found the fix about this problem. I have problems with process like issch.exe which was taking 25% cpu usage and starts lagging like hell, one year i resolving that process with "End Process" in task Manager, but after this second problem, your problem become my problem too.. I buy and install program which is called "Malwerbytes" Anti-Malware Premium v.3.1.2.1733 and run the scan, i have 19 threats in my pc and cleaned it all. After that i was not have problem at all.

If this not helps you or anybody else, the problem is behind "Taskhost.exe" which in the process you will find more than one "taskhost.exe" and that means that the trojan or whatever is behind one of them, he masking himself to not be found. Cheers!

Check the task scheduler, I had the same problem and found some shaddy miner tasks running every minute

I had the same issue as the rest of you... playing any video on or off-line would lag after a few seconds, sometimes a minute or more of playback.

This is just a simplified way of describing how you get to the Task Scheduler... follow these steps:
WindowsKey (on keyboard) > ControlPanel > AdministrativeTools > TaskScheduler > TaskScheduler(Local) > TaskSchedulerLibrary

If you see anything related to bitcoin or blockchain or anything you don't like (Google the name first before jumping to conclusions please) just disable the task or delete it altogether.

P.S. I was also thinking of re-installing Windows but it's a nightmare and I have things to get done GD it!

Roguekiller64 portable is a classic for finding this junk....

I started having this same issue within the past couple days, and I thought it was due to the new Nvidia drivers that just dropped. I just scanned with Malwarebytes anti-malware, and it found quite a few bitcoin miners. Hope this did the trick.

You can troubleshoot it for days, or, wipe and reload (delete partitions/reinstall) in 10-15 minutes, assuming you have installation media on USB, and are using an SSD drive...; will take 30 min if installing from DVD to a spinning drive...

Gather your required chipset and GPU drivers ahead of time...

I had been having the same issue on and off for a long time, and I FOUND A SOLUTION.

For me, HARDWARE ACCELERATION in Chrome was causing my issue. The whole video in Twitch would freeze (the audio would continue), but the video would work fine once I started moving the mouse and would continue to work when I moved the mouse in circles.

I fixed it by going into Chrome's advanced settings and disabling "Use hardware acceleration when available".

Seems to have fixed it.

Thanks philip-42, I had the same issues with video lag, I followed your advice and problem solved.
