Spiritsong,
True, the program has not been around long enough to be considered "trustworthy" yet at spywarewarrior, who say this about it's
de-listing as "rogue" (in March this year):
Note on SpywareTerminator: We originally listed Spyware Terminator on this page out of concerns that Crawler, the company behind the product, had established connections with IBIS, a well known adware distributor responsible for such adware programs as Wintools, Websearch, & Huntbar. Although we found no problems in our initial testing with Spyware Terminator, and while the vendor itself announced that it was exiting the adware business (1), we decided out of caution to impose a three month probation period before we would consider re-testing and, if warranted, de-listing the the product from the Rogue/Suspect list. During that three month probation period we monitored the behavior of IBIS and Crawler. At the end of the three month probation period we re-tested Spyware Terminator, again finding no problems serious enough to justify listing the program on this page. As the vendor involved has not been involved in the distribution of adware for many months, and as the program itself exhibits no problems serious enough to warrant mention on this page, we have decided to de-list Spyware Terminator from the Rogue/Suspect list and can no longer regard the program to be "rogue/suspect."
Note: not to be confused with Spyware X-terminator from Stompsoft

However, if you look at the opinions of a few users, who haven't been riddled with popups and adware since installing it, (quite the reverse, in fact), you might perceive a different view.
My opinion, for what it's worth, is that the application is trustworthy.It's definitions are not as broad ranging as some, there has been the odd bug in it's development, it's not always straightforward, particularly for a newbie, to set it up correctly or to know how to respond to an alert. A check of the forum content will reveal this, and more. It will also reveal a genuine appreciation of the product. My PC is important to me. (That's why I use Avast). And I'm quite happy to have ST guarding the malware side of it.
