Hello there and welcome to BleepingComputer. My name is Charles and I will be dealing with your log today.
I do not recommend that you have more than one antivirus product installed and running on your computer at a time.
The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other antivirus products to create "false alarms". It can also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection.
In general terms, the two programs may conflict and cause false alarms - when the antivirus software tells you that your PC has a virus when it actually doesn't. Also it can cause system performance problems; your system may lock up due to both software products attempting to access the same file at the same time.
Therefore please go to Add/Remove in the Control Panel and remove either McAfee
Please download HostsXpert from here
Then click on "Restore Microsoft's Host File
", followed by OK
at the prompt.
Close the program when complete.
Once you have done this, I would like to see a new HijackThis log in your reply.
