I know nothing about viruses. recently a message appeared on my computer saying that i needed to clean computer to avoid itt being crashed and prompted me to click "clean computer" following which a security warning came up regarding the file which was entitled "warderinformationdetect.pl. I then closed computer. Cant remember what was on the original warning i think Microsoft was mentioned and three viruses detailed. a friend of mine told me that no anti virus was on the computer and he activated AVG Anti Virus Free Edition 2012. My query is it safe to transact on line banking now. Apologies if all this seems puerile!
