Yes it can be trusted, however...
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."

So use it at your own risk if the company ever re-establish
contacts with IBIS. I recommend you use other softwares such as
Ad-aware or Spybot which has more reliability
