Yes. Spyware Terminator offers the option of integrating ClamAV's signatures into the Spyware Terminator's Real-Time Shield signatures. According to what one of the Spyware Terminator techs told me a while ago, integrating ClamAV's signatures with Spyware Terminator's increases the effectiveness of the program's Real-Time Shield. In fact, during the fore-mentioned episode with MySpace, it was the Clam element of ST which caught the malware. I realize the potential for conflicts between two antivirus programs, but my Avast and my Spyware Terminator have existed peacefully for quite a while with not one problem.
I am by no means a software expert, but I intimate from two other posts currently on this forum that the Avast! program seems to be detecting the antivirus signature "JS:ScriptSH-inf[trj]" in other programs, Spybot and ClamWin (I believe ClamWin and ClamAV are different programs, but am not quite sure). This is the first signature that my Avast! has ever detected inside another program, and over the years I've used it with Avorax, Threatfire, Windows Defender, Spyware Terminator, SuperAntiSpyware, Spybot, Malwarebytes, AdAware, among others. I have had more luck (and fewer conflicts) with Avast! than with any other antivirus program I've ever used and it is my favorite AV software. That's why I was hoping that perhaps the people at Avast! might be able to rectify the conflict.
Actually, if not, it's a relatively minor niggle, and a simple matter of checking "No Action" on the warning box.
