I just bought and installed NOD32 today. I'm in Tawain and needed to buy the v3.0 Singapore version then downloaded the 2.7English version. Anyway I'm not sure if I have a virus on my system or not. Acer Aspire 5735Z laptop, Vista Home Premium dual core Pentium, 160Gb, 2Gb RAM, etc. I installed the program and it is running but it never did an automatic "Initial Scan" like every other AV product I've tried, is this normal (do I have to manually run a scan the first time I run and install the program)? I've tried 3 or 4 times to scan the In Depth, Local and Run NOD32 scans from the NOD32 menu and every time after about 20 minutes it just stops on the folder: C:\ProgramData and just hangs there forever. I basically need to Ctrl-Alt-Del to get the scan to stop. I've heard for years that NOD32 is the best AV program out there. I've used Norton for years and it has been heavy, but always worked. I'm sad to say that I paid $50 for NOD32 and the thing can't even do a complete scan of my computer. Any help of feedback would be appreciated, thanks.
