Does anyone have any information on the G-Lock Temp Cleaner hard drive cleanup utility? Downloading via G-Lock's website, you can get two versions of the installation file. Download site 1 offers 'download-gtc.zip.exe'. AVG Anti-Virus gets alarmed by this file - 'Warning: Hidden extension .exe'. Download site 2 (when it's working) gives 'gtc.zip' which AVG passes as clean. Is AVG needlessly panicking?
