Strange rootkit detected?
Recently, a few AVG users reported unknown rootkit infection detected. Although rootkit techniques could be used by legitimate applications for various purposes (e.g. copy protection), we recommend thorough checking the system if unsure, whether there could be a malicious rootkit present. More information about rootkits and how to remove them can be found in the following FAQ articles: What is rootkit? How to deal with rootkits?
If you believe a rootkit is detected while in fact there is no rootkit technique employed, please provide us with more details as described in this AVG Forums post (the Anti-Rootkit False Positives part).
