AVG writes "Please note that rootkits can be either correct or malicious. Correct rootkits may be installed as a part of legitimate application. The list of some well-known rootkits can be found in the FAQ 2346. Because of that it is necessary to pay close attention to the Anti-Rootkit results."
Since it's on the whitelist and AVG documents why this is so, no further action is required.
Hello. I just installed AVG free version 10. Did a rootkit check and have 272--all "white-listed" or "hidden" so not removed. What does this mean? ANy rememdy? I have windows XP home SP3. Thanks kindly.
