The picture looks like textbook graphics corruption.
The crash however is clearly blaming AVAST! for your problem.

Probably caused by : aswSP.SYS ( aswSP+afaf )

Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arg1: fffffa80058ffd10, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.

If you are willing to remove avast my two suggestions are ESET or MSE
Anti-Malware, Virus, Spyware Protection | Microsoft Security Essentials
MSE is free as well though. If you run it and scan manually about once a week with malwarebytes
Malwarebytes : Malwarebytes Anti-Malware is a free download that removes viruses and malware from your computer
you have a stable and relatively safe system.
Obviously you should at least turn on windows firewall as well now.
