Interference with HP Photosmart 6520 printer

[A.G.Tufan]

Hello Everyone
My home info:
-ISP KPN Netherland
-Printer HP Photosmart 6520 (+ Deskjet 3070A)
-2 laptops Sager 9370, Samsung RV720
-2x Avast internet Security
-win 7 pro x2

I have allot of issues with interference between avast and printers on my home network printer(s) (wireless).
Printers keep disconnecting after a few hours, after a night, from the laptops and can not scan and print.
Even when put laptops to sleep (ps: tried shutting down same no changes)

I have contacted my ISP it is not from the rooter. (changed rooter, changed house but not because of printer )
I have contacted HP they offered a outstanding support calling me 7 times in 2-3 weeks they used a similar program as team viewer to modify things in my laptops and still the issue continues
I turned off firewall, problem keeps persisting.
Turned of avast permanently on 1 laptop, so far everything ok with printer on both laptops

I have bessicaly tried everything that me, HP, ISP  can think of

Any solution for this would be helpful besides running to pay another antivirus i would really miss avast (i have posted some photos of errors)
Thank you

i see in one of the images you have a lot of tempurature monitors running. i have had a few issues with these causing the problems with drivers crashing, especially with anything that has storage.

speedfan seemed to be one of the culprits that would cause issues on my network, i would run it all the time and it would be fine and after a while would just cause all my external drives to disconnect.

try stopping them from starting up and see if the problem is still there.

Avast shouldn't be causing such a n issue on your whole network.

I tried that today sadly still get printer disconnect
The programs were HD Sentinel and Core temp 1.0

Thank you roguekiller23231 for the advice did not try that until you mentioned it
