Good Morning- Windows Vista Home Premium (32-bit) SP2 ESET NOD32 version 4.0.474.0 I just downloaded a sceensaver. Knowing how notorious these type of sites are for delivering some type malware I wanted to check the download before installing. I 'Right Clicked' the .exe file and clicked 'Scan with ESET NOD32 Antivirus". The On-Demand scan showed 1 file scanned and no infections. However, when I opened the .exe to install I received the NOD32 popup window with the "Warning: Potential threat found" message. I deleted the file. Of what value is the On-Demand Scan via the context menu, or should I ask, what exactly does the On-Demand scan identify? Thank you in advance.
