In testing done by CNET Download.com, Trend Micro Anti-Spyware finished scanning in slightly more than 11 minutes. Thanks to the integration of InterMute's highly regarded CWShredder program, Trend Micro Anti-Spyware 3 does a better job of finding and deleting all traces of the notorious CoolWebSearch family of browser-hijacking spyware than most competing products; however, a confusing removal process requires that you first blacklist all found spyware threats. After two scans, the program turned up different numbers of spyware threats and included false-positive spyware traces that were independently found not to be on the test system. When Trend Micro Anti-Spyware finished its removal process, we were disappointed to find that it had left Bookedspace, Search Exe, and 180 Search Assistant, as well as other minor traces.
The integrated help system is adequate to handle basic questions, but Trend Micro's online FAQs weren't exactly helpful when it came to Anti-Spyware 3. The searchable knowledge base wasn't any better; it was confusing and seemed to contain very little information about the Anti-Spyware product. Luckily, technical support is available at no extra charge via both telephone and e-mail, with a guaranteed response time of 48 hours.
