What to do if my computer is infected by a virus or a malware?
My system has got infected. I want to download and install an antivirus. I can't access any antivirus site. I have checked the host file. It is not allowing the USB drive too. What options I have now? Apart from these two, my system is working fine. Operating system : windows xp sp2. EDIT : have scanned by malwarebytes. Did not find anything.
