I removed my AVG, installed KasperSKy and scan the system, it mentioned that the trojan has been removed to Quarantine.
I have uninstall the KasperSky without uninstalling the Quarantine. Re-Installed the AVG.
Now it seems that trojan has been activated, I cannot update my AVG as It doesn't let me to connect to internet!
Can anyone give me a hand and let me know if I do have any other option except the formating and re-installing windows.
P.S: I am using windows 7 home premiume.
