i don't usually share private info. sorry if it sounds weird to you. i can't share you the transaction details with you though the wallet isn't a private one. i use this wallet for small transactions only.
i'm using electrum atm. afaik it's safe. i have downloaded this from authorized website- electrum.org
i had no transaction within last few days other than the one i sent to my friend. i didn't have any other bitcoin address around at that time.
is this info enough? i guess you are right that i have been infected with malware. gotta get out of this.
