This has happened twice to my father's computer, one on Feb. 20, 2014 and once on April 18th, 2014. Using his @AOL.com email address someone has accessed his account and has been sending fraudulent emails to his address book. In other email providers there's a way to view account history that will show the general locations where users have logged in at, but AOL does not seem to have this option from what I was able to find.
I checked my father's computer history and logs and didn't see anything that stood out (ex: no porn, Russian music sites, torrents), so I thought to run a series of checks on his computer. The following software/systems did not find any problems:
Malware bytes full scan
Hijack This log (I went through, nothing wrong that I could find)
He hasn't downloaded anything recently.
He doesn't do much on his computer outside of casual web browsing and emails.
When this happened in February I advised him to change his password, which he did and AOL has a log of this. But it happened again.
I'm not sure what the problem is and I'm not sure where to go from here. As you can tell I'm new to this site from a posting stand point and I do apologize if I am not in the correct section, but I am concerned my father's computer is infected with something.
Please note, he does not use the AOL browser but accesses his email through IE 10… I’ve migrated him to Gmail for some of his email usage but he still uses his AOL email often. If it is of any assistance, here is some of his computer information listed below.
OS Name: Microsoft Windows 7 Home Premium
Version: 6.1.7601 Service Pack 1 Build 7601
System Manufacturer: ASUSTeK Computer Inc.
System Type: x64-based PC
Any assistance is appreciated. If there is anything additional I should provide please let me know.
