Insanely high HDD activity from Chrome and IE.

[Pete.Dakota]

Started happening the other day. I've got "Enable phishing and malware protection" unticked in Chrome which is supposed to reduce HDD read/writes, and I'm using the "--new-safe-browsing" trick too. I know Chrome generally has issues with HDD spam, but never had it from IE before.

Why are they both doing so much to my hard drive? I'm not downloading anything.
