I was having this same issue, just started yesterday in the evening.
BAD_POOL_HEADER
Tried system restore to move everything back to the 20th... Still same problem... (Thought it was a just-installed-app, at first). Seemed to be trigged by attempting to use USB3 (LINKSYS) wifi stick.
Uninstalled Malware Bytes, after seeing a thread about other people having the same issue on reddit.
For some time though, it kept saying no realtime protection after rebooting.
Windows defender is disabled.
Leaving it uninstalled for now. Hopefully someone here can email if the issue is resolved, or if more information ( hardware specifics, dumps, logs ) are needed.
Windows 10, i7 2600k, 32GB DDR3 (Corsair with XMP profile enabled... passed MemTest86... thought it could be bad bit in RAM at first, common reason for BAD_POOL),
GTX 980ti, Crucial 960G SSD, USB3 PCI-Express card, Hardware RAID card.
UFEI booting, ASUS motherboard, USB3 LINKSYS WiFi stick.
To be honest, if I don't get contacted about the issue being resolved... It will probably stay uninstalled and i just won't renew. I shouldn't have to come back regularly to find out if a major problem like this was resolved.
