PC Tools Threatfire 4.5
PC Tools Threatfire 4.5 is a free behaviour-based antivirus utility that serves as a great supplement to your existing security software, offering superb behaviour-based detection.
- Superb behaviour-based detection, works with existing security apps
- Cannot perform regular antivirus scans
Although Threatfire is designed to run with other apps, and we had no problems in our tests, it has conflicted with AVG in the past. That aside, we recommend PC Tools Threatfire 4.5 as a strong extra layer of defence. It's free, so grab it.
PC Tools Threatfire is not a stand-alone antivirus program. Instead, PC Tools Threatfire 4.5 supplements your existing security app with highly effective behavioural analysis that can stop malware based solely on what the file tries to do on your PC.
Behavioural detection attempts to thwart the successful hacker tactic of churning out ever greater numbers of malware variants to stay one step ahead of traditional antivirus signature databases (which the majority of security programs use). Other programs employ behavioural or heuristic techniques, too (the latter looks for partial matches with known malware). But behavioural detection like the approach that PC Tools has implemented in PC Tools Threatfire 4.5 can be particularly tricky, as it's prone to accidentally flagging harmless software.
In AV-Test.org's behavioural-detection tests, most apps have only about a 30 percent to 60 percent detection rate. Not so for PC Tools Threatfire 4.5: It warned about every single one of the 15 malware samples used, and it blocked all but one of them. What's more, this nimble malware nabber didn't put up any false-positive warnings. It's hard not to be impressed with such stellar performance.
While running more than one regular antivirus app at the same time can cause major problems, PC Tools Threatfire 4.5 should run smoothly alongside existing security tools. Since it detects only programs that attempt to run, you'll still want a standard antivirus program to perform regular scans and to check files that write to your hard drive, before they get a chance to execute.
PC Tools Threatfire 4.5 is simple to use and defaults to an appropriate medium level of sensitivity, but we suggest turning on the option in Settings, Quarantine to create a system restore point automatically before quarantining anything. As for extras, a nice system-activity monitor provides extensive technical details about all currently running programs, and a mostly just-for-show threat monitor maps global malware outbreaks.

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
If you’re looking to invest in your next work horse laptop for work or home use, you can’t go wrong with the MSI GE63.
If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
Touch screen visibility and operation was great and easy to navigate. Each menu and sub-menu was in an understandable order and category
The printer was convenient, produced clear and vibrant images and was very easy to use
I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.
