My Security Shield is rogue antivirus software, and it and all of its iterations and family members are part of a scam. My Security Shield aims to take over your computer, scare you into believing that it has found your computer to be full of viruses, and convince you to pay for its useless, bogus software. It tries to make itself look like real antivirus software or a windows component, with a realistic-looking interface that may even use Windows graphics and fonts, but this is all meant to trick you. Under no circumstances should you pay for or intentionally download My Security Shield.

Different Name, Same Malware

My Security Shield is just one iteration of a long line of malware programs that are basically identical. It was especially prominent in early August 2010, and seems to be showing a resurgence in January 2011. Earlier versions of this same malware were Security Master AV, My Security Engine, Security Guard, CleanUp Antivirus, Virus Doctor, and Smart Security. Other currently circulating versions of the same malware (members of the same malware family) are Windows Defence and Internet Antivirus 2011. The family of rogue anti-virus programs to which My Security Shield belongs to has been around for a while. My Security Shield has been traced to an origin in Russia, and so it follows that these other versions of the same malware are also almost certainly from Russia.

As is typical for rogue antivi-rus malware, My Security Shield usually infects a system by way of a Trojan, although worms and other viruses have been reported. The Trojan that delivers My Security Shield is always hidden in a download or a file that seems harmless. Once it has been unpacked by the Trojan, it sets itself up to run whenever Windows starts, and to redirect you to its own malicious website when you try to access any of the major Internet search providers. When Windows starts, My Security Shield will run a bogus system "scan" and turn up a whole list of scary-sounding infections and problems. The ironic thing is that most, if not all, of these threats that it reports are garbage files that it created so that it could detect them as "malware." It may also list perfectly ordinary programs or Windows components as threats.

Aside from the fake system "scans," My Security Shield will constantly bombard you with error messages, which claim all kinds of horrible things are happening with your computer. If you try to kill My Security Shield using Task Manager, it will shut down Task Manager. Similarly, if you try to open any actual anti-virus or anti-spyware software, My Security Shield will prevent that from opening, too. My Security Shield will tell you over and over that something is wrong with your computer and that it can fix it, if you buy the full version or the product key. My Security Shield is not real antivirus software, and you should not pay for it, no matter how hard it works to try to scare you. The site you are redirected to after agreeing to buy the software or the product key certainly will take your credit card number and charge you for the "full" version of the program, but it will do no more than that. Product keys are never received, and My Security Shield is incapable of performing any antivirus or security functions.
