Hello,
Windows 8.1 64 bit is my OS.

I have received the following blue screen errors the past few days


Bad_pool_header
driver_corrupted_pool
page_fault_in_nonpaged_area(WiseTDIFw64.sys)



driver_IRQL_not_less_or_equal(afd.sys)

I had been using Panda free antivirus but it blocked my internet connection so I switched to avast free. Is it possible that is the reason I have been getting the blue screens? If so how do I know if this caused the blue screens? I did a scan with avast and it did not find any viruses or malware. Malwarebytes scan found no detected objects.
If that is not the reason what else is the cause of the issue? If it is a driver issue how do I check? Is it safe to replace a driver if needed?
According to drive booster these are the current drivers needing updates.




If any of the above is not the issue what is the issue and how do I resolve the issue?
Thanks for your help.

You could go into Task Manager's StartUp tab and uncheck those programs causing issues as a troubleshooting step.




page_fault_in_nonpaged_area(WiseTDIFw64.sys)


This is related to the Wise Care product, stop it from starting at startup or uninstall it completely.




driver_IRQL_not_less_or_equal(afd.sys)


is your network card driver, best to get the latest driver.


I don't know the Driver Booster application. Often you can get driver updates from Windows Updates, are you all up-to-date with those?

I have 9 optional Windows updates would you suggest I install all of them? Where should I get the network card driver from?
I don't have any programs name Wise Care in my installed programs list.
What do suggest my next steps be?

Start by uninstalling any unneeded or unrecognizable programs from Programs and Features, but do your research first.

For the optional updates you can install them but they likely aren't hardware driver updates since those are always named appropriately.

You can get those driver updates from your helper software, I did a little research and it seems legit.

Afterwards you can use the free version of Ccleaner's (https://www.piriform.com/ccleaner) features.

Is drive booster the helper software? Do you suggest updating all the drivers it lists? If not all of the drivers which ones should I update? When I updated drivers on a previous PC it messed it up so that I had to do a system restore to fix it. If I do update all the drivers hopefully that will not happen.
Do you think if I update all the drivers that will resolve the blue screens I am getting?

I suggest that you also as part of this to check your hard drive for errors. You could have a bad sector and it coruppted the driver.

Then be sure to update all your drivers with the latest ones.

Here are results of a WhoCrashed scan

47650

Do these results mean that avast is the cause of the bsod? If so would you suggest uninstalling and reinstalling avast? If you think I should use a different antivirus which FREE antivirus do you suggest using?

You may want to examine this thread to see if it relates to you. Try some of the suggested methods and keep us posted.

I submitted a support ticket to avast. I have not heard back from them yet.


Here is another whocrashed report

47670

Is this 47671 the same item that is in the whocrashed report? If so should I delete it? Do I use right mouse click and delete or how do I delete it?
