hi wondered if anyone could help upon scanning my laptop with AVG i came across a damn trojan which is deleted now but it also found a reading error just says file: hosts. result/infection: reading error. path: C:\WINDOWS\ststem32\driversetc\hosts. Checked the path it is a back up file entitled hosts.bak. BAKfile. Anyone know what this is? is it safe to delete? what should i do please help. Thanks in advance.
