Here's something else I found handy that I'm adding to the list.
Trojan Killer 1.3
Download Trojan Killer 1.3.3.1 - A malicious computer software (malware) removal tool. - Softpedia
I was infected by Win32: Trojan-gen,something questions are being asked about all over the intenet and not many seem to know how to get rid of.
I used Avast,which spotted it but couldn't get rid of it,same for AVG,also Malwarebytes Anti Malware couldn't get rid of it.
It affected Internet Explorer giving anoying pop up advertising every couple of mins.
It did not affect Firefox however so I used firefox till I found a way to kill the Trojan.
2 days later I discovered Trojan Killer 1.4 which done the job.
