The link you gave is clearly about XP and the time frame where SSL died. Since you don't run W7, I think you must be asking about something else entirely since I see no file renaming in that discussion.
I bascially have this issue:
But I don't understand the solution(s) proposed. How will my security protection be compromised by changing the file name?
Also wanted advice: I was going to buy lastpass initially but saw password management was a feature on kaspersky as well. what do you think of these antivirus providers who also offer the password management feature? I'm a little concerned about locking myself into a program associated with my antivirus, in case I decide to change programs or in case any vulnerabilities with the program mean vulnerabilities with my passwords as well. Do you guys think its better to diversify in this case? Or is it just a waste of money investing in a separate program?
