Good afternoon everyone:
Yesterday morning, I went to check my yahoo email account.
In the spam folder I noticed a email to me from one of my other Yahoo accounts that I use when I sign up to online forums.
I obviously didn't send it to myself, so did some investigating.
I don't have any contacts in that account, and it looks like the spam email was sent to the two addresses I had in the sent folder, although the spam email itself was NOT in the sent folder. Nothing in the account settings appears to have been changed.
I logged into that Yahoo account. When I checked in the account information section, it showed someone had accessed my email at 4:14 am from Thailand via Yahoo Mobile.
I don not use Yahoo mobile, and in fact own no mobile devises capable of using the internet. I went to another computer in the house and immediately changed the password for that Yahoo account.
So, the question i have is, does my system have an infection, or is it an issue on Yahoo's end?
I have run full scans of my system using Norton Internet Security 2012 (up to date), Malwarebytes and SUPERantispyware. All came back 100% clean. Could there be something on my system these programs aren't picking up? Should I try running them with windows in safe mode?
i somethimes use my PS3 to check my emails instead of turning my computer on. Is it possible for the PS3 to get infected with maleware/viruses?
Any information you could provide would be greatly appreciated.
