Reason is, "Reputation." Is it safe to shut down my anti-virus and install anyway?
Do you know what is "reputation" criteria in Norton's antivirus?
Reputation Scan compares the files on your computer with those about which information is submitted from the computers of millions of other
Norton users. From Reputation Scan, one can learn how common or rare these files are across
Norton users, whether those files are trustworthy, and their age.
Reputation scan sounds like it involves public opinion,
but actually Symantec analyzes usage information from millions of
users in the Norton Community to derive reputation scores for applications. In particular this analysis notes how prevalent the program is among Norton users, and how recently it was created.
A program with just three users that was created yesterday is much more likely to be malware than one created last year with 3,000 users. This is little too presumptious, if you ask me.
So... since now perhaps we know, let us not suggest, that BMS files are harmful. And .... do not shut ever antivirus, just use better one!
