I installed it on my PC and also followed the instructions to download it onto a jump drive. I ran the program on my PC, (took a LONG time) and found29 items. I clicked the tab that said "Fix PC" . . . I then put my jump drive into my laptop and it did an install from the jump drive. I ran the scan. The scan found a bunch of stuff related to the Edge browser, However, this time when I clicked the "Fix PC" tab, it asked me for my registration key. So, I went back over to my desktop, retrieved the code and carefully entered it. I got a message saying the key was invalid. I tried a few more times and got the same message. I then contacted the manufacturer and told them of my issue. I received an e-mail with a "ticket number" but have yet to hear back from them.

Due to many false positives and uncertainties I posted fair comment and a question that appears to have been deleted.

Given similar findings relating to this and an earlier Giveaway version - plus a number of negative online reviews, I am glad to have rid my computer of Trojan Killer.

Downloaded and installed easily. Using "Standard Scan", it scanned 57,494 files (over 400,000 on my computer) in 5 minutes using 37 detection types and found 55 problems.

Problem 1: The window is not resizable. I could not read the full problem , so I exported it to a log file to read it.

Problem 2: I don't know how to interpret the problems. Why are the following examples a problem?

2a-- c:\users\owner\appdata\roaming\mozilla\firefox\profiles\5rzqm5wx.default-release-1\user.js ---- General PartOfThreat Susp.PL.Gen.vl MD5: CC279550DFE2E28FA099883AA3F95166:886

----- HKCR\Interface\{C8159E37-5EDF-4E6D-8E6D-E558E8DDC2A0} ---- Registry Threat

I would like to know the difference between "Standard Scan" and "Full Scan". Actually, I would want to know much more about what the program does and how it does it before I would purchase it. Especially, I will not delete anything unless I know what the problem is.

Thanks to GAOTD and Gridinsoft for making this program available for evaluation.

Well, so much for that. "Installed" without a problem, but refuses to activate. Getting popup boxes that state the "Connection is down or busy. Please try again later." The activation screen itself says "Oops! Check your internet connection settings or try again later." Nothing wrong with the internet, nothing blocking outgoing traffic, just doesn't work. This is the first program I've ever had a problem with from here, so I'm 99.9% confident that there is nothing on my end causing the problem. Guess I'll try again in a little while, maybe their activation servers are having problems...

I do find it funny that a "portable" piece of software installs to C:\Program Files\Trojan Killer\ by default, and also installs parts of itself into C:\Users\[user]\AppData\LocalLow\. It also creates a start menu link, adds entries into the local PCs registry, as well as creating an "uninstall" entry in Programs and Features (Add or Remove Programs). Not sure how any of this stuff makes this software "portable".

I've been trying for over 3-1/2 hours to get this to activate, or even successfully contact the update servers, and it just won't. Claims that it can't contact them and that I need to check my internet connection.

Thanks anyway, but useless in its present state. Uninstalling.

I downloaded this to my Windows computer and it installed with no problem. Told it to run a full scan. Part way through it froze the whole computer. Had to do hard reboot. Ran a clean up program, then ran Trojan Killer without anything else running, in case having a browser open had caused the previous problem. Came back a while later and screen was black, computer unresponsive. Had to do a hard reboot again. Uninstalled Trojan Killer.

I have a laptop that never goes online or on a network or on the Internet, there are only DOC and PDF files in that laptop.
As a curiosity, I ran this portable software on that laptop, results, exactly the same suspicious files found there as on the main computer connected 24/7 on the Internet.
If you think I'm pulling your leg, do the same experiment and post your results. I'm little skeptical that Trojan killer like this really removes anything from your computer, because all the known Trojans are always morphing, hide under the operating system files with exactly same names, but slightly different spelling and in different sub-folders with same name as your OS or in different names that first must be detected from a known d-base at the developer's side and do regular updates of such Trojans in your software.
What happens between the updates it is a gray area and an unknown, Trojans can live and do the damage to your computer. The best thing is to have virtual system running all the times, when such computer is switched off, everything is return to the previous state and nothing is loaded secretly into your files.

unbelievable number of false positives more than 50% of items scanned were false positives tried stopping the scan and the UI did not provide a true way to exit the scan entirely just paused it and only way out of the paused state was a back arrow button that recommenced the scan... lifes too short to fight this... no User interface to end program... Task manage had to be used. suspected PUP's and suspicious items and suspected adware are NOT Trojans!
Uninstalled with prejudice!

Hmmm thought this was supposed to be a portable program? Yet the setup.exe installs into C:\Program Files\Trojan Killer\ by default and offers a desktop shortcut and installs a start menu folder and shortcut... calling a program portable and then installing it without even an option of putting it onto removable storage is a little deceptive to say the least!

So claims portable but is fully installed but is allegedly USB thumb drive friendly if you manually copy to a USB stick after fully installing it.

Reply   |   Comment by TK  –  Last year  –  Did you find this comment useful? yes | no (+1)

Bob, the problem with that bodge which you can do with most any program that does not claim to be portable in the name too is that you still get the uninstall entry in the Program and Features window of Windows as well as an folder in the Start Menu too without even giving it permission to install a desktop shortcut to a USB thumb drive that may not always be there... It's not a portable distribution and that is a fact.

Reply   |   Comment by TK  –  Last year  –  Did you find this comment useful? yes | no (+2)

On my production desktop it found nearly 100 trojans.
Upon inspection of the file names they are mostly (probable ALL) false positives. Like links to an exe that I know is harmless.
It found the gnumerics installer (a very good freeware spreadsheet) to be a trojan: very hard to believe.
Also all portables I made with Cameyo are flagged as trojans.
A Giveaway from 2011 is also flagged. Etc.

I cannot recommend it.

Installed fine on win 7 pro x64.

. Very pleasant interface
. Fast

. Took forever to update virus listings, on first use, even over a 70Mb broadband connection...
. Though it says it is essentially a "portable version" it defaults its installation to the PC and then suggests to run install again for a usb if portability is desired...
. Annoying rules: though no registration KEY is required (as stated in the .txt file included) it does generate an ACTIVATION code it then sends to your e-mail for safekeeping. What for, I ask, if you can only install it during the GAOTD period?
. The .txt file says that "free upgrades for future versions are valid for 6 months", but the e-mail received says this software's key is free for 14 DAYS...

What's going on? Is this a free portable edition for "life" (without upgrades or support, of course) or not? Why use confusing words?
Not complaining, just giving some feedback on what I saw upon successful installation.

The software reports many false positives. Everything from "The Windows Sysinternals troubleshooting Utilities" among many others. I uninstalled it, because I don't want something that "erases" what it shouldn't. Be very careful.

This is a very dangerous utility. I just installed it and ran a scan and fix without going through the deletion list carefully. Now several of my utilities were permanently deleted including Wechat, Weiyun drive, and QQ from Tencent as well as KOPLAYER and BlueStacks (both are Android emulators). If you don't have any of the listed here, maybe it is good for you. Or check the list before hitting the CurePC button. Good luck to you and I will remove it now.

I installed it and ran it and it found items, and then told me I had to buy a license. What did I miss?

Reply   |   Comment by NIna Macdonald  –  Last year  –  Did you find this comment useful? yes | no (-1)

The program window is an unresizable 657 x 450 pixels - did the programmers phone it in ... on a rotary phone?

Like Malwarebytes, they think everything is a PUP, including paid-for programs that get 0 hits at VirusTotal.

Oh well ... it found 5 empty references in the registry, I suppose that was nice to clean.

The 500+ other items it found are stuff I use on demand, tools, like from GOTD, that have 0 hits at VirusTotal.

At this point in anti-everything programs such as Gridinsoft Trojan Killer, I need them to tell me more, such as "this is adware in the fact that ..." and then specify - if I have opted-in to give feedback to the programmer, that's not malware, that's participation, like here at GOTD, where we give feedback to software programmers.


The usual criticisms apply - no control over program window size, no right-click on items to get information and go there, and so on, same same for so many other programs from programmers who seem to ignore everything we tell them about what we want.

Before I start with this, does it ask me what I think of the scans? Or does it just delete without my approval/unchecking boxes etc. ?

Reply   |   Comment by dave c.  –  Last year  –  Did you find this comment useful? yes | no (+25)

dave c., You do get the opportunity to survey what it has found before deletion.
It also has the facility to reset your browsers back to original settings too.

Installed flawlessly. Reminds me the way GridinSoft Anti-Malware works, also a GOTD give away. Takes a few minutes to run but I have a ton of things on my puter. Just make sure you read carefully what you delete. T/Y GOTD.

I've been using this product since its last GAOTD offer. I use it from a USB flash drive when PC's exhibit virus infection behavior.

It's been my experience that it works quite well.

It has detected and eliminated malware from several systems that a PC's installed anti-virus software including GridinSoft's standard anti-virus product) did not detect.

STEVE A SPURLIN, what are you doing that causes your PC's to "exhibit virus infection behavior."? Only infections I have have EVER had unintentionally since using windows based computers are W32/induc-A virus. Which I then figured out how to patch the infected files to castrate the infection with a single byte patch. After manually repairing my Delphi dev environment of course.

Anyway, it took a long while but I was using my browser at the same time tho it was hard work. The program seemed to be locked on the '1 minute' countdown for around twenty but it finally got there and pleased to say ALL 19 finds were suspicious and I have not noticed any losses in functionality

The lack of the ability to set a Sys Restore point is very concerning and I would be very interested to hear from Gridinsoft if this will be included in later offerings and if not, WHY not?

Reply   |   Comment by Terry I  –  Last year  –  Did you find this comment useful? yes | no (+26)

Bob, Thanks
Appreciate that but not everyone is savvy enough to know to do this. Perhaps if the program made mention of it when first run, would be sufficient.

Reply   |   Comment by Terry I  –  Last year  –  Did you find this comment useful? yes | no (+10)

Terry I, you should not rely on restore points as they can and do fail especially with advanced trojan activity that may bypass VSS disk writing interception and break the VSS database integrity causing a prior restore points to fail. Real offline system backups should be made at some point if you really want to go back to previous states cleanly.

Definitely read the comments at https://www.giveawayoftheday.com/trojan-killer-portable/
folks. The software -- in that version, at least -- seems to have a distinct predilection for
false positives, and not only deletes what it deems to be offending programs, but everything
in their folders, too. Proceed with great caution.

Thanks for the heads up, krypteller.

"The software -- in that version, at least -- seems to have a distinct predilection for false positives"

There was/is a major campaign in the news that started with a Solarwinds attack & compromise.


Once FireEye found it [they'd been compromised too], they were able to release malware signatures. And that, in a nutshell, is the weakness of pattern-based malware detection. The compromise has been ongoing for most of the year -- you can't match what you don't know about, and minor modifications can render yesterday's patterns useless.

Apps like Trojan Killer Portable, Kaspersky's standalone rootkit scanner etc. can be useful because they're not installed, which actually introduces vulnerabilities [e.g. malware often tries to disable or exploit installed defenses], but they're limited to known malware signatures, and because there's no heuristics / monitoring to help reduce risk, can tend to have their sensitivity dialed way up, meaning more false positives.
