For Prevx version 184.108.40.206: This is a trivial case, as the item detected was just a "low risk adware" object. I do however have to question why it took Prevx so long to detect this "threat" on my computer. Here's the rundown of my situation: *I have a folder on my Desktop called "Folder A" *In "Folder A", I have one ISO image and one folder. "ISO 1" and "Folder 1" *Files in "Folder 1" were used to create the "ISO 1" image *Both "Folder 1" and "ISO 1" therefore have the exact same files - specifically ATAINF.EXE (this was the file flagged as the low risk adware) I have had Folder A on my desktop for a week. I have run multiple scans with Prevx and it never detected anything. Just a few moments ago, I went ahead and used "Folder 1" to create "ISO 1". I decided to scan ISO 1 just for the heck of it, and it found ATAINF.EXE as a threat. Prevx then prompted me to reboot the computer to complete the removal process. Upon reboot, Prevx performed another full system scan. It also found the ATAINF.EXE file in my ""Folder 1" and flagged it as the same low risk adware. So my question is: why did Prevx not flag that file as a threat until after I scanned the ISO image with it? As a sidenote, it seems it would be a false positive. Prevx was the only scanner out of 42 to flag it as malware when it was analyzed through Virus Total. Also, I should add that I am running Prevx alongside with Threatfire 220.127.116.11 and ESET Smart Security 4. Reason I mention this is because I have heard that some programs may conflict with one another, and may actually result in a reduced level of protection - thus, could Prevx be conflicting with either Threatfire and/or ESET Smart Security?
