3 days ago, AVG antivirus alerted me on the presence of Trojan horse Patched_c.LYU. The infected file was found on Windows/System32/services.exe. I am confused because AVG detected the virus on the said file but it cannot be removed from the system because it is in the white lists.
I noticed two unfamiliar things since the infection of Trojan horse Patched_c.LYU virus. One is my browser is redirect to other web site when I clicked on a search result links from Google. Another is the warnings I received from Facebook each time I start to log-in. Other than that, there is no more symptom of the infection. The computer acts normally and Trojan horse Patched_c.LYU does not affect the performance at all.
I hope someone here can help me remove the virus from my computer. If you can provide simple instructions or a removal tool, I would be very glad to accept it.
