Just had a virus infection on my USB disk which then transfered to my PC. NOD32 (Smart Security specifically) did not detect it as a virus. I only noticed it when an unfamiliar exe file wanted internet access. I then upload the file to virustotal.com and it came back 22 out of 32 virus scanners detected it as a virus. Kaspersky detected it as Worm.Win32.AutoRun.aw, which is what im using now to scan my computer after the discovery of this virus. Im surprised (and a bit worried) NOD32 did not detect this virus.
