Hi, everybody. I am running Windows Vista Home Premium 64-bit and I set up a limited User account for everyday use to make sure that my administrator account is safer. I was running Malwarebytes' Anti-Malware and I came across 2 infected files that I couldn't delete and McAfee couldn't detect. So I found the files and uploaded them to VirusTotal.com and it said they were infected by the hiloti! trojan. The trojan has infected two dynamic-link libraries in the AppData folder and it appears that they are important, so I can't delete them. The trojan tries to download more trojans once in a while but I know exactly where it sends them and am deleting them as they appear but I would very much appreciate a permanent fix. FYI, the .dll files are a toolkit for burning discs from Padus and a Cyberlink Library.

Hi,
I'm just curious, where did you download these programs from? And have you tried to scan with Eset's online scanner at www.eset.com/onlinescan? Eset is very good at cleaning without deleting where it can. In my experience, I've had it clean things while still leaving the legit part of the file intact. Eset are very well-known for that.

Hope this helps,
Regards,
Chromebuster

I'm pretty sure they came installed on the computer, I never really had to dig around in the hidden folders until recently. I will try your suggestion, though. Thanks.

Use TFC instead.

TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download link
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
