So my sister calls me today stating her Chrome browser is showing a windows update page and downloading a file that her antivirus, Kaspersky Internet Security 2011, keeps red flagging and sending to quarentine, this happened no matter what page she went to, Facebook, google, etc..
Burned a copy of her OS, WIN 7 home premium 64 bit incase reformat was inorder, grabbed my bootable kaspersky recovery usb stick,Packed up the kids and went to her house and saw the same thing, at this time she informed me her messenger, MSN, was failing to connect as well as her antivirus was failing to update and now complained of a bad blacklist, normally this would be a sign of a cracked or stolen copy of the antivirus program but seeing as I bought this for her and still have the key I knew this wasn’t true,
Rebooted her pc onto the Kaspersky recovery key and tried to update its definitions, that failed, I opened its internal browers and low and behold the same page came up.. then it struck me some one could be deploying a MITM attack either through her wireless router or her internet so either way I took her router out of line and pugged her directly into the modem, automagicly the problem was solved,
I updated the definitions and ran a full deep scan anyway with no Virus or otherwise found, at this point she has no need for the wireless AP so I left it out of line untill I can futher assert what happened either way that’s my interesting story of the day and as I said I trust Kaspersky, the rescue edition can make either the usb key or cd which is linux based, a complete plus in my book
I leave you with this
If two operating systems on the same computer of seperate origin( linux, windows, etc) experience the same problem its not normally the pc at that point but though for me 99% its not always the case
