A fairly old computer I aquired has Trend Micro Chipaway on it, whenever I boot-up I get a message saying Trend Micro has detected a virus on boot-up. It gives me the option to hit enter to see more information, or to hit N to boot-up normally. The computer boots up fine, and I even ran AVG, Malwarebytes, and Housecall, all which didn't find any viruses or malware. So, should I be concerned? I read that you can disable Chipaway in the BIOS, but just wanted some advice on this.
