got my account stolen lucky it had NOTHING of importance associated with it so they may as well have gone and registered themselves a free gmail account 
I used my gmail account on 3 devices.
1)Samsung galaxy S (this was running a custom (but trusted) rom from xda developers site, I have not had the phone for well over 6 months)
2)Sony Ericsson android phone (stock 2.1 rom, unrooted)
3)Sumvision tablet (budget device, android 4.1 rev1.4 from their website)
Turn on the table the other day having not powered it up for several weeks to see a few new emails in the inbox 1 from blizzard entertainment that I believe is legit but the message text is entirely in Chinese so I have no idea what it says and another message from goggle saying someone in china tried to log into my account but the action was blocked.
it also seems I have either forgot the account password or it was changed.
my phone is mostly running wifi disabled and I rarely enable grps (does wonders for the battery life)
when I do use it that account Is only used on my tablet and my phone.
I suspect the tablet because I used the account recently on my tablet (few months before the unauthorized login attempt) to authenticate an associated account (trusted site) and had to tap my password into the tablet.
so far I have left both devices disconnected from the internet and installed avg, both scan reports come back clean but I suspect it may be only scanning user installed apps?
also looks like I can recover the account but I need to make a secondary account in order to do that so I figure just let them keep the account and start over with a new one but I want to make sure my devices are clean first.
tldr : is there a better scanner I should try see if it picks up on any keyloggers or anything avg would miss ?
Thanks
