Recurring POPUPS from Avast!!!

I keep get a recurring popup from Avast. It says Malicious URL Blocked.
These are the two that I get.

URL: http://t.webbster.net/click/?s
Process: C:\Users\User\AppData\Local\Temp\sfhxcws\srvdxwt\wow.dll

URL: http://t.webbster.net/click/?s
Process: C:\windows\syswow64\svchost.exe

I have ran a scan and a boot scan and found nothing infected. Malware Bytes also finds no infections.
What can I do? Please help!!!

Please attach your logs. (AdwCleaner, MBAM, OTL and aswMBR…!!)

Hi,
Should I run Combofix and/or Zoek?

Not until you’re instructed to do so. Please be patient.

Hi lets clear the temp files first and see if that resolves it

Hello, I ran OTL again with the new commands. Here is the report. The problem seems to be fixed!!

Thank you essexboy and Asyn

Don’t go away just yet.

essexboy will either give you the all clear or ask you to run another program. Wait for him to respond.

If you are happy then run OTL and press the cleanup button to remove it
