It was the one used in business not commercial so not sure about heuristics

Sunbelt VIPRE is probably my first recommendation for those paranoid about security and associated threats. Lightweight antivirus yet including very good anti malware capability.

Personally, I use Windows Defender (built in) on my Windows 8 machines and system center endpoint protection on my non-Windows 8 machines. (i.e., security essentials if you like)

Try this.

1. Use Tune Up 2010 - 2013.
2. Open configure system start.
3. Turn off iehighutil.exe
4. Delete iehighutil.exe in system start.
5. Open Manage running programs.
6. Terminate process iehighutil.exe
7. Close Tune Up.
8. Open C:
9. Delete C:\Temporary
10. C:\Temporary\iehighutil.exe should now be deleted.
11. You can now empty the Trash.

Just noticed that this virus seems to be back on my computer, any ideas what to do next?.
