So Saturday I get a strange email from my wife’s Yahoo account. One of those “Hello” in the subject and “I thought you would enjoy this link” messages. I immediately knew it was crapware.
My wife has a netbook that she takes around and uses on open (free) wireless networks wherever she is. She also does not turn it off but rather just closes the lid. Apparently while opening an email (she is a couponer so she opens any and all emails) her machine became infected. Even though I have talked to her about the dangers her attitude is “I have got your to fix it if something happens”, my issue with that is about four times a year I am cleaning a big mess of the laptop, and this time the infection allowed the hackers software to have access to and harvest our Yahoo email password.
What I did next is exactly what I preach here and what you should do. I turned off her laptop. I then went to another PC in our SonicWall protected network (I have NEVER had an infection make it through the SonicWall – contact me for a quote on one that will meet your needs). On the clean PC I logged on to Yahoo and changed my password.
Next I ran my security software on all computers (except the netbook). First Malwarebytes then Spybot and finally ESET. All machines were clean. On the netbook I ran Combofix, TDSSKiller then Malwarebytes, Spybot and finally ESET. I ran them all in normal mode (I did not bother with SAFE mode at this time). After running those (which takes hours), I logged on her system and did a little surfing, cleaning up Internet Explorer, installing Firefox and its security add-ons I have mentioned numerous times (WOT, Adblock Plus, Ghostery, and NoScript), she had not been using Firefox because “she did not like it”, which really turned out to mean the security add-ons kept me from clicking on anything and everything.
Regardless, after a Saturday night spent cleaning all computers I have a story to tell. The moral, don’t jump on any and all open wireless networks, get a SonicWall, even for your home, use Firefox with the security add-ons and quit clicking on every darn email.
Until we meet again, have a virus free week!
