When I challenged Trend Micro to protect a virtual machine test system from my current collection of malware samples, it wiped out 66 percent of them on sight. It whacked quite a few more when I tried to launch them. Its detection rate of 89 percent and overall score of 8.9 put it in between F-Secure Internet Security 2015 and Bitdefender Total Security 2015.
I tested the product's ability to block malicious URLs using newly-discovered URLs supplied by MRG-Effitas. When initially tested, Trend Micro's 80 percent blocking rate for malicious URLs was a new high score. However, a few days later it was deposed by McAfee AntiVirus Plus 2015, which blocked 85 percent. Both scores are impressive, given that the current average is 32 percent.Symantec Norton Security, tested simultaneously with Trend Micro, managed to block 51 percent.
A full scan of my standard test system took just 20 minutes. Because Trend Micro avoids re-scanning files already found to be safe, a repeat scan finished in less than a minute.
Trend Micro's impressive handling of malicious URLs also carried over to my test of its phishing protection ability. Its detection rate lagged just 4 percentage points behind that of Norton. Very few products come close to Norton's fraud detection rate.
Small Performance Hit
I wondered whether the additional installation of the password manager, safe browser, vault, and especially SafeSync would make this suite more of a resource eater than Trend Micro's entry level suite. In fact, its scores in my performance tests were the same, within a percent or two.
My boot time test, which measures the time from the start of the boot process (as reported by Windows) until the system is ready for use took 31 percent longer with this suite installed than with no suite. Given that most people rarely reboot more than once per day, this probably won't be noticeable.
A script that moves and copies many large files took 7 percent longer with Trend Micro watching. That's actually a bit better than the current average of 9 percent. And another script that repeatedly zips and unzips those files took 13 percent longer, just a little above the current average of 10 percent.
There are definitely suites with lower overall impact. Webroot's average impact across my three tests was just 3 percent. F-Secure and Bitdefender averaged 4 percent. Even so, I doubt you'll be able to perceive any system slowdown after installing Trend Micro.
Note: These sub-ratings contribute to a product's overall star rating, as do other factors, including ease of use in real-world testing, bonus features, and overall integration of features.
