Dear All, I have a problem. Here is what happend: 1. I executed some .exe file on my Windows 7 with MSE installed 2. MSE didn't trigger any warnings about exe file 3. Just in case I sent file to virustotal.com and virustotal stated: MSE - nothing NOD32 - infected with Win32/HackTool.Patcher.A 4. Immediatelly I bough NOD32 anti virus. Uninstalled MSE, installed NOD32. 5. Scanned the same file locally with NOD32 that I sent previously to virustotal.com Result = nothing. No viruses found. Any ideas why virustotal reports the virus with NOD32 and NOD32 itself cannot find it. Any ideas?
