Before we begin, please be sure that HiJackThis is in its own folder. This will allow us to use backups to restore entries if necessary. Please do not put HiJackThis in a temporary folder, or on the Desktop. I suggest using 'C:\Program Files\Hijackthis\' or C:\HiJackThis\, but any name you choose is fine.

Reboot in Safe Mode* and run HiJackThis. <-- IMPORTANT

Check the following items in HijackThis.
(note: If any R* items do not appear in Safe Mode, re-run HiJackThis in Normal Mode and remove them after you finish removing these items.)

Also, uncheck the boxes for hiding known file extensions and hiding protected operating system files. We want to see it all. When we finish here, it would be a good idea to rehide the protected operating system files but leave the rest to be shown.

Reboot in normal mode

Run HiJackThis again and post a new log in this thread.

Your log indicates that you are running more than one AntiVirus product which provide real time protection. There is nothing wrong with using more than one AV as long as only one provides realtime protection. Using more than one AV for realtime protection may lead to system slowdowns, conflicts and possibly corruption.

Also, uncheck the boxes for hiding known file extensions and hiding protected operating system files. We want to see it all. When we finish here, it would be a good idea to rehide the protected operating system files but leave the rest to be shown.
