It looks obvious

I never liked Symantec’s anti-virus . When I had it installed on my old Sony Vaio it use to be very generous using the computer resources, making it difficult for any other thing, and wasn’t so efficient detecting viruses.

Today I found out that not only it wasn’t great anti-virus it was harmful and increased risk for users:

“The anti-virus vendor acknowledged that it was deliberately hiding a directory from Windows APIs as a feature to stop customers from accidentally deleting files but, prompted by warnings from security experts, the company shipped a SystemWorks update to eliminate the risk.”

The only way to convince companies like Norton and Sony to stop from harming their customers is to stop buying them. Being humble is the first rule, and if they forget it we should remind them.
