While online today, my AVG anti-virus detected a Trojan virus and instructed me to run AVG if I want to remove it. I ran AVG and it didn't detect anything. I tried some free online virus scanners and they didn't detect it either. Any thing I can do to remove it? I didn't pay attention to what file is infected because I simply thought that AVG would find it once I did a scan. Know of any other Trojan scanners I could run to find the virus?
