I have been using Eset Internet Security for about 2 years.
This morning Chrome browser started to give warning about a data breach, when I visited a trusted website and wrote my account information/email and password combo to sign-in:
"A data breach on a site or app exposed your password" and it recommends me to change my password.I noticed it is related to one of my accounts, whenever I use that email and password combination on some websites , Chrome warns me with the same message.
It may be probable that a website which had my account information, got hacked but I think that the problem may be different.
Yesterday I visited some potentially dangerous websites which had potentially malware stuff.I rarely visit those websites and it might sound silly but generally I do it for the purpose of testing my security software.I know that it is dangerous and that no security product can give full security.Though still, I don't download and run .exe files from those websites, I only visit some of their pages.
I didn't give any account information on those websites but I strongly think that they took my account combination information from my pc, somehow.
About 2 years ago, while I was using Eset Internet Security trial, I was testing the product by visiting potentially dangerous websites.In the same days, I had visited another security vendor's forum page and wanted to register for the forum, but that website had given me a warning similar to Chrome's warning.
And a few months ago from present, when I wanted to sign-in for a popular game server, after I wrote my account name and password, that page suddenly started asking me my cellphone number.I contacted the support staff of the game server and told them that I never wrote a cellphone number into my account details, they told me that my account was stolen and then they reset my password so my account got recovered.
My question is, is it possible that while I was visiting potentially dangerous websites, my account name and password combination got stolen somehow and not detected by Eset Internet Security?(or maybe I wrongly chose "allow" when it asked for permission to allow connection)
Note: I have an account for this forum actually but I decided not to sign-in to it for asking this question, it is the same account/password combination which was stolen and I thought it might be a bad idea to use it while asking this question for probable security reasons.Though of course I am changing the password soon.
