    I and family members have seen a nasty increase in malware emails that most likely will plant a Ransom Virus if the attachment is acted upon. We now get several every week and sometimes several in one day. One of the most insidious is an email where the sender is spoofed to be Amazon. The "Amazon" message will seem to announce a shipment having been sent. However, there are two tell tale warning signs: 1) It is sent to an email address that only my friends and family know. I use a different email address for Amazon. 2) The message is empty, except for an attached Word document. Amazon never attaches Word documents to their emails. Like I'm going to open such a Word document and run the risk of a malicious macro getting run on my machine. :| The other type will be an empty email from myself to myself. It has an attached zip file that contains a Javascript file. If you look into the message header it is full of Arabic characters and is sent from a domain in Iran. Of course I am in the habit of running Javascripts from unknown sources on my machine. :| Now here's the bummer: If I scan these obviously malicious messages with Defender and Malwarebytes, they come up clean! I was wondering if anyone else has had similar experiences?

    Usually I don't - I mean, U receive a lot of those e-mail but they are egregiusly filtered by Big G spam filter and end up in the Spam folder. I rarely receive spam or phishing between the good e-mails.

      Just under 5% of the emails I get are junk: adverts, spam, phishing, and such like - nearly all of which I never see because it goes straight to my "junk mail" folder via the Live Mail rules I have set up. Every now and then I go through and forward phishing mails to the supposed originator. But so far I've not seen anything like you describe. I still do regular-and-often backups though! :laugh:

          Probably! I find that if you have a backup, you probably won't need it. If you don't... :laugh:

            Yup! And having full backups takes fear out of the equation, doesn't it? Knowing you can recover from an attack gives you peace of mind, even if it never happens. ;)

              And the fake tax refunds, had one that looked very much like an HMRC mail, but they don't send attachments.

                  Don't worry. Letting windows update own your computer and rule your life will solve all your problems. Oh, wait... No it won't. It'll just "fix" things that work. The best process security and peace of mind is, and has always been, "don't do anything stupid". If you use Outlook (the MS Office version), one trick is to drop suspect files into the "Junk E-mail" folder before opening them. That disables anything that could do a nasty. But I prefer the "If in doubt, delete" method. Failing to open a genuine e-mail will not add or remove a second to or from your lifespan.

                    Well, gosh, don't you have a filter in your e-mail whatever that is at least flagging these toxic billet-doux, routing them into a special folder (as in Chrome's 'Spam folder) ? If I were ever crazy enough to open one of those '.doc files, or run some kind-a strange JavaScript, I suspect my Emsisoft software would catch them and warn me.

                      Precisely! Same here. But maintaining good backups does not hurt. Ransom viruses are also spread by hacked "good" websites. There is always the risk of visiting a supposedly safe website that has been hacked.

                        I use Office 2010. It does not have the greatest spam filters. However my ISP does filter for spam. However, some messages still make it through to my inbox. :sigh:

                          Had the exact e-mail before. A good metric to see what scanners are good is to upload the attachment to http://www.virustotal.com and see which scanners detect it. Neither MalwareBytes nor Symantec picked it up when I checked awhile ago.

                                      But why worry? If your own, personal files (which are a tiny proportion of the files on your PC) and your configuration details for various programs (which don't amount to five beans' worth of disc space) are saved to other locations, then all you lose is an OS -- and I'd be quite happy to lose any OS higher than Win 7. Just use another machine while the "attacked" one is getting everything reinstalled and copied over, and you haven't lost a peanut.

                                        I am in total agreement with that. All that unnecessary junk steals my bandwidth even if my browser settings block it from being rendered. If I may also play devils advocate, I also understand that many websites depend on advertisements to supply their operating capital BUT the broad spectrum tactics that most ad services utilize, showing you a million ads in hope that you click one, is reliant on quantity and not quality. In my opinion, one or two high-quality, content-targeted ads per page is more than enough. Three dozen ads trying to sell me the latest pharmaceutical product or another product that I have no need for is a waste of money on both ends and does the advertising industry a disservice.

                                          Mark, When I am attacked by Ransomware, it takes me less than 10 minutes to totally recover and clear my computer of the virus. (It has happened 3 times.) If data files are corrupted by the virus, add the time to overwrite the corrupted files from a backup that was disconnected at the time of the attack. Can you beat that? If yes: I would love to hear how!
