Hetty,
I think you are good to go.
I would do a few things to finish up:

Open OTL and click the CleanUp button. This will remove most of our tools and associated folders.

Run a full Scan with Symantec and have it remove anything it finds.

-----------------------------------------------------------
To increase your protection going forward I would recommend use of a HOSTS file.
It blocks inadvertent access to thousands of harmful websites.
Be sure to follow the whole two-part procedure, and get the DNS Client service disabled BEFORE installing the HOSTS file.
-----------------------------------------------------------
Replace the Current HOSTS File with MVPs
You can read about HOSTS files here : http://www.mvps.org/winhelp2002/hosts.htm

• Disable DNS Client Service. This is necessary when installing a large HOSTS file.
  From Start, or Start, Run
  Type services.msc in the box and hit <Enter>
  Give permission to continue if necessary.
  Scroll down to DNS Client on the list, Right Click it and choose Properties.
  Under Service Status, click Stop. Wait until it reports the service stopped.
  Under Startup Type, choose Disabled.
  Then click Apply, OK
  If this procedure was successful, proceed with the installation as follows:
  
• Use HostsXpert to Install the HOSTS File
  Download HostsXpert and unzip (extract) it to your computer, somewhere where you can find it.
  
  • Double click on HostsXpert.exe to launch the program. Give whatever Permissions are required.
  • In the bottom half of the left pane, click on File Handling
  • If the first button at the top is labeled Make Writeable?, click on it so the label changes to Make Read Only
  • Click third button from the bottom, labeled Download. A couple new buttons will appear at the top.
  • Click on the top button labeled MVPs Hosts and choose Replace
  • When asked to verify if you want to Replace present Hosts file, click OK.
  • When it finishes, click on File Handling again.
  • Click the button at the top labeled Make Read Only, so the label changes to Make Writeable?
  • Hit the X in the upper right corner to exit HostsXpert

If you have a separate third party firewall, or Winpatrol, you may have to give permissions at various times to Unlock the present default HOSTS file and install the new one.

Good Luck !
