High CPU usage (100%) on Random applications. (Applications using 50%)

https://www.youtube.com/watch?v=l6JT-3CJMeI

Lately I've been experiencing High CPU usage on random application. It's becoming really annoying and cutting down my productivity on already slow, crappy laptop.
I've tried everything:
*Virus Scans
*ProcessExplorer (and all solutions related to it)
*Defragging
*Attempting to enable DMA on SATA drive (Doesnt work because my drive doesnt have that option)
*Simply ending the processes.
*I would hold overheating responsible but then my pc has been overheating for a long time now and that doesnt stop it (Not to the point where it randomly shuts off, but to the point where I close it down [laptop] and after entering stand-by, it shuts down)
*I made sure to uninstall other anti-viruses, so that it wouldnt compete with malwarebytes.
*Im still installing a whole lot of windows updates, hoping that the fix might be among them.
*I tried a system restore to a date before this happened...No luck.
*I've tried plugging it out and then in again 3:
*Ive tried updating drivers

Hi Inquixitor and welcome to Seven Forums!

Same problems if you boot to Safe Mode? If that helps try this as a next step:
Troubleshoot Application Conflicts by Performing a Clean Startup

*ProcessExplorer (and all solutions related to it)
Including enabling VirusTotal check from the options menu? That will check all running processes against 50+ antivirus products. Start Process Explorer as Administrator so it can check system processes too.

Instead of killing a process from Task Manager it's better to use Process Explorer and first Suspend the process, then kill it. In case of malware infection this reduces it's chances to automatically restart the process when you kill it.

So, Im using the virus check in Process Explorer, and so far I've found a virus in a process that's used with DaemonTools... Not sure if it has solved the problem, because malwarebytes is using 50% CPU, not sure if that's normal. If it isn't, Im going to follow your first suggestion.


Thanks so far.

I didnt go in safe mode, but I went ahead and tried step 1 in the link. The problem persisted. So I decided to scan a few more things.

The virus in all chrome processes is Antiy-AVL :Trojan/Win32.SGeneric

The VirusTotal results are only showing for a few of your processes. You should start Process Explorer as administrator so it can check all processes including those running as system, services etc. Or you can go to the File menu and select "Show Details for all processes".

Process Explorer can't remove infections, only show the results from VirusTotal. If only ONE anti-virus detected something it's not necessarily an infection. It's likely a false positive, a wrongly detected "infection" by a specific anti-virus product. A detection from several anti-virus products are more likely a true infection.
The purpose of checking VirusTotal with Process Explorer is to perhaps get a first clue IF you have lots of infections. Because it checks with more than 50 different AV's it's a very fast way to get an first overall picture of all the running processes.

*I made sure to uninstall other anti-viruses, so that it wouldnt compete with malwarebytes.
Malwarebytes Anti-malware is not a true anti-virus product and should not be a replacement for a real anti-virus product. For example it can't detect older viruses. Malwarebytes made the product that way on purpose since it's only meant to be a complement to an anti-virus product. Malwarebytes focus is more on newer threats, primarily what's called Zero-day and Zero-hour threats. So if you only have Malwarebytes you do not have a good protection.

*Virus Scans
What virus scans have you tried?

I suggest you try booting to Safe Mode. It will load Windows with minimum drivers required and without 3rd party products. It the problems goes away in Safe Mode, you should try the link I posted before to do a clean startup:

Via, false positives, check this out



49/55 sites claimed there was a virus, but when I did a second scan, it came back as 0/55....

I'll do the safe mode thing now...

Looking at your screenshot, I believe your PC is heavily infected.

The Sality malware can according to Win32/Sality :
  • Stop your security software from running
  • Steal your sensitive information
  • Download and run other files
  • Delete security-related files from your PC
  • Lower your PC security settings
Your online accounts, credit cards etc could be compromised!

You could try the MS Free Malware Removal Tool | Anti-Malware Scan Software

But I suggest you consider doing a clean install of your entire system.

I wouldnt switch to mac just because you got a virus. Even mac's can get viruses. My brother is a hard core apple person as he buys old macs, refurbs them and then resells them; and in his last mac he somehow got a virus. So no, even apple stuff is not impervious to viruses. I would stick with windows.
