Hello everyone, First, I apologize for my (very) bad English ... I am a new customer of Prevx. I am satisfied because Prevx is really efficient, lightweight and impact on performance is minimal. To all: Congratulations to the development team. However, I found some problems / bugs: 1 / if I right click to scan a folder containing multiple files Prevx tells me I noticed that one result: 0 files, 0 programs. If I start again a scan on the same file then Prevx indicates the correct number of files scanned. Below is a screenshot to show you the result during a first scan: 2/ Each day I am testing urls on MDL and I see that Prevx will not detect most infected pdf files ... I changed the settings of the heuristic, but it does not change anything ... Here are some example URLs: ~ Virus Total Results Removed per Policy ~ Thank you for reading. Good day! Note: I am running Win7 32Bits with Prevx just installed (no other antivirus).
