Trojan horse Small.GUH Virus Removal

Hello! I use AVG anti-virus, the free version, and 2 days ago, it found Trojan horse Small.GUH virus (object name c:\Windows\System32\svchost.exe) and shows it is removed. However, each time it says it has taken care of it but then it shows up the next time I scan. So is the virus gone or not? There is nothing showing in the Virus Vault and I’m concerned. Why didn’t AVG block it in the first place if it was a well known virus. And what is the best way to get rid of this virus without coming back? Any help will be highly appreciated.
