Hi all
Recently I've been getting some high CPU usage for no apparent reason. My processes give no hint to what it could be, and I've heard that I could have a bot on my PC. That said, I ran a full system scan (avast antivirus) and it's come up blank.

Here's a screenshot of the type of activity (look to the right)

If someone could help me with this, I'd be really grateful.

Many thanks
