Recurring Malicious URL Pop-Up

I’m hoping someone here can help me out with this problem that’s been happening the last 2 weeks.

Every 5 minutes I get an avast pop-up warning saying that avast has blocked a malicious website from opening. This happens all by itself, when I’m not opening anything. It comes from the same place every time, and this is what it says:

Infection Details
URL: hXXp://ycxv.net/result/?affiliate
Process: C:\Users\myname\AppData\Local\OverDrive…
Infection: URL:Mal

Additionally, when I open some sites from a google search, the page I open sometimes gets re-directed to a different spam site full of ads.

I’ve done full scans, a boot time scan, a Malwarebytes scan, and it hasn’t found any viruses on my system. Any ideas?

Thanks!!!

Please ‘modify’ your post change the URL from http to hXXp, to break the link and avoid accidental exposure to suspect sites, thanks.

This needs further analysis by a malware removal specialist:
Go to this topic http://forum.avast.com/index.php?topic=53253.0 for information on Logs to assist in cleaning malware. Use the information about getting and using the tools and attach the logs here, not in the LOGS topic.

Ok, I’ve done the scans and attached the logs. What should I do now?

also attach aswMBR log

What should I do now?
now you wait.....malware removers are notified but it may take hours before on arrive

Let me know if this stops it
