Solved No malware, OK hard drive, but 100 CPU and insanely slow!?

March 21, 2014 at 19:23:19
Specs: Windows 7, 3.00 GB (2.74 GB usable)
One day,my Advanced System Care kept on telling me that it blocked something from changing my homepage. Then all of a sudden, the CPU skyrocketed and my computer was as slow as a snail.

For about two weeks, I ran MalwareBytes multiple times (and deleted everything it said was bad) until nothing showed up. I ran CCleaner, SUPERAntiSpyware, and AdwCleaner and fixed and deleted everything. I checked if my hard drive was failing through command prompt and CrystalDiskInfo (both said the hard drive was OK).

Everything in the previous paragraph was done in Safe Mode.

I've talked it through with a friend (he's a computer geek). He said he would trust MalwareBytes for finding the malware, but other than that, he had nothing to suggest other than resetting my computer back to factory settings and starting over.

That's the last thing I want to do.

First, I don't know what's up with my computer. Supposedly, there's no malware and thehard drive is OK, but for some reason, the computer is really slow and the CPU refuses to come down. Second, I don't know what to do anymore. I think I've done pretty much everything a homo sapien can do to save a computer.

Thanks,

Harrison

Good rule of thumb.. If you don't need it - better to get rid of it.

Which version of CCleaner have you installed?

I have never had anything even remotely sounding like Spigot install with the genuine CCleaner...

Per chance did you download one of the several other "versions" which try to pose as the genuine CCleaner, and aren't? Some even have almost identical names...

This is the genuine (free) version...

When you install it - do a manual setup (not an auto setup or whatever they call it) and deselect (decline) any suggested add-ins or offers to change "anything" . Simply install only the utility.

did you look in task Manager and see exactly what it is that is using the CPU.

Install Process Explorer from Microsoft because it will show you better what is running on your system.
When you have a better picture of what is running, Run msconfig, go to Start tab, and uncheck all except Microsoft items and your antivirus program (you can add back anything you later need as you notice any), Apply and let it restart the machine. Go directly into Safe Mode and rerun Malwarebytes. Open Programs and uninstall anything you did not install and is not otherwise needed, Google anything you are not sure about that you see. Restart in normal mode.
Let us know the progress and results.

You have to be a little bit crazy to keep you from going insane.

Another thought:
Do a System Restore to a date well before the problem and repeat above in the same order.
If it is a root infection and these do not help, you will probably need to do a full restore or reinstall. Back up first or course!

Get rid of Advanced SystemCare & SuperAntiSpyware. Stick to CCleaner & MalwareBytes. Open CCleaner, click on Tools > Startup & disable or delete all unnecessary or useless entries. Do the same on all the tabs (IE, Firefox, Scheduled tasks, etc). Reboot.

Just to add that most system care type programs are capable of introducing more problems than they fix. SuperAntiSpyware is a legitimate program but generally MalwareBytes is favoured around these parts.

Junkware Removal Tool can sometimes unearth things:

There was nothing that I was able to see on Task Manager that used up all the CPU...

I'll try the Process Explorer.

I've tried System Restore, but it didn't really fix anything.

I'll try out the CCleaner again

Thanks for offering the Junkware Removal. Will try it out now.

Also, I talked with another friend today. He told me that updating my BIOS or something like that might help my computer. Is he right?

Better to follow one path of problem solving at a time... Do the clean out routines suggested above first. Then consider other paths...

Just found Spigot on my system...it was included as one of the programs that start up with the system on CCleaner.

I heard it was some kind of malware, though it doesn't do too much damage.

The one I have is the genuine one.

I prevented this Spigot thing from starting up with the computer. Should be okay now.

Just one more note: do NOT update your BIOS unless you know you are having a problem that the updated BIOS is listed as correcting or when you need it for advanced compatibility (like a newer CPU). The danger is if the BIOS update fails, you may never be able to use the motherboard again.
