Notes about the SNU file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The SNU file type is primarily associated with 'AVG' by AVG Technologies. AVG is anti-virus software that uses the following technologies to detect computer viruses: Scanning - searching for character strings that are characteristic of a given virus; Heuristic analysis - dynamic emulation of the scanned objectís instructions in a virtual computer environment; and Generic detection - detection of instructions characteristic of the given
virus/group of viruses.
