Anyone else Using both Avast AV and CCleaner Pro and Chrome as browser? I have been getting this Url:Mal Alert "Network Shield: blocked access to malicious site hxxp://18.104.22.168/casino/CA?subid=177622288614&zoneid=408912&sxid=st33du0i2815 ([22.214.171.124]:80) [ C:\Program Files (x86)\Google\Chrome\Application\chrome.exe ( 5388 ) ]" I have yet to get this when I disable CCleaner Pro background monitoring! So if your answer is yes to the topic and you have been noticing Url:Mal alerts like mine shut down CCleaner Pro's background monitoring and see if the alerts ceases to occur. Post here also if you are experiencing similar alerts by Avast. Maybe it is just a coincidence I don't get the alert when CCleaner isn't monitoring in the background? Maybe something infected a file that ccleaner is using but it would have to be a file that isn't removed and reinstalled when I uninstall CCleaner Pro and reinstall it! This may occur with other browsers but I don't use any others. Regards, Trevor Issue Solved! It was Popup Blocker Pro extension.
