Multiple chrome.exe *32 processes running and constant anti-virus pop-ups.

Hi,

Since a week I've had multiple chrome.exe *32 processes running while having chrome open. All these processes also use a lot of memory and cpu capacity. I have already followed this guide (http://malwaretips.com/blogs/remove-chrome-exe-virus/) but the processes are still there. Ran full scans with several anti virus and malware programs like ESET, Adwcleaner, avast and roguekiller. I'm running out of options so I am hoping that anyone can help me.

Thanks in advance!
