do you run ublock origin?

do you run ublock origin?

no

do you run ublock origin?

no

I would suggest it as it might reduce CPU usage. Toms shouldn't be creating that much traffic so it might be adware

Tries running malwarebytes on PC and see if you have anything installed you don't want.

i tried to scan with malwarebytes -hitmanpro - rkill

no viruses detected

there is such a thing as Java script CPU mining, I can guarantee Tom's isn't involved in it but this might ofer some insight: https://www.gizmodo.com.au/2017/09/how-to-stop-pirate-bay-and-other-sites-from-hijacking-your-cpu-to-mine-cryptocoins/

If you install Ublock Origin on all browsers on PC and Laptop it should now block these attempts. The filters were added soon after the ability was discovered. Ublock exists for all major windows browsers, including edge.

The article also shows how to block them in adblock.

using ublock fixed it but i want to know is there a virus infecting sites or iam infected and why antiviruses didn't catch anything if so

I wanna say that, somehow you're the one whose infected. Cause I installed nocoin and it doesn't come up on this page.
Interesting that even malwarebytes didn't detect it... uhh did you like already have it installed from long ago? and not update it? though I think it runs an update when you do a scan...

Restart your computer?

 

[Islam_610]

i restarted and installed new windows the only fix is to disable JavaScript or use extension that blocks miners

What anti virus are you using? Try downloading the free version of Bitdefender and see if it finds anything

 

[Islam_610]

iam using malwarebytes
i tried bitdefender didn't catch anything too
i noticed that the high cpu usage happen after ad sites open like (ONCLICKREV)
then malwarebytes blocks crypto-loot.com domain

another good reason to use ad blockers. Ad companies must hate these people who figure out ways to exploit their services. How are you going to convince people to not use ad blockers with this sort of stuff happening?

I don't know how it works, since it doesn't happen on every site it must be triggered by particular ads? It would be interesting to find which exactly.

only ways to stop it is No Coin or Ublock or blocking domains or script blockers - http://www.thewindowsclub.com/block-websites-using-cpu-mine-cryptocurrency
