Just the other day I, inadvertently, ran a Trojan (not as hard to do as one may think) which managed to download to A.N.Other the various site passwords which were stored in my browser. This was a real stupid situation to get into and it was only discovered once I had been banned from visiting one site.
Using an online scanner the Trojan was found in less than ½ hour but it took me almost all of the rest of the day to change my passwords at the various forums and sites I visit.
In retrospect, it pays not to have your browser remember passwords and it is not a bad thing to change passwords on a regular basis.
As T.J. once said “The price of freedom is eternal vigilance”.
Tweakie.
