To make it short I was browsing the internet and out of nowhere Bitdefender blocked several viruses (I didn't catch there names it happened so fast.) how can I be curtain Bitdefender did its job and blocked these viruses? I'm in the process of scanning my computer with Bitdefender, Malwarebytes Anti-Malware, Trendmicro Housecall and GMER so far they haven't found any viruses.
