I just installed Avast Internet Security 5 and are now having issues logging into any website where I have to enter a username and/or password…ex. bank account, facebook, etc. etc. I had Avast Home Pro before and never had this issue. During installation everything seemed to flow. I even tried disabling all of the shields and firewall but I’m still having issues. Any suggestions?
what antivirus did you have before avast ? have you removed it ?
do you have more then one firewall ?
Prior I had Avast Home Pro and McAfee at the same time and I didn’t have any issues. So right now I have Avast Internet Security (don’t see anything Home Pro anymore) and McAfee. In what order should I uninstall and re-install?
Thanks!
start with running the McAfee removal tool and reboot, and with some luck thats it… 
McAfee is #20a http://uninstallers.blogspot.com/
why you should never run more than one AV ( see reply from quietman7 )

Why Shouldn’t I Install More Than One Antivirus Program At A Time?

Thanks for your help!! I followed your instructions. It definately had something to do with McAfee. I uninstalled McAfee per your instructions and then re-installed the Avast. Everything seems to be running fine now. Again, thank you very much!!! I love Avast as it has caught stuff that McAfee hasn’t so I don’t mind just running Avast.
Glad i could help…
I also recomend to run Malwarebytes. it works great as an extra scanner along side avast…run it now, you may be supprised :o …OBS always update it before you scan.
