My computer is infected with Bob.718.a. I found many files with the name Bob.718.a in my computer, so I searched for the file on the internet. That time I came to know that it is a virus. I could not understand why Escan antivirus, that I am using in my computer could not alert me about this virus. I scanned my whole system, but still it showed no infections in my computer. So, I am totally confused with how to remove this virus. I am using Windows XP operating system and my browser is Internet Explorer 8.
