I am using Quick Heal Antivirus software, which is the best and affordable for me. My desktop is safe from unwanted virus attacks from last 2 years. MY vote to Quick Heal.
i am using avast antivirus. If avast!'s very good malware cleanup doesn't recognize a suspicious file, its built-in automatic sandboxing can keep that file from doing harm.
I am using M-cafe from last couple of months and get good results from it.
It is very sharp in getting new threats and provides complete Computer support .M-cafe has good scanning speed as well.
I will suggest you to go with M-cafe to get complete web security.
