Today is my unlucky day, I got an emergency situation earlier this morning, my computer was infected by TROJ_CRYPTFILE.SM. To by honesty, I don’t know how I got this virus in my system in the first place, it doesn’t matter, I was told by a technician before, it’s inevitable to get virus sooner or later as long as you surf the internet, since my antivirus cannot solve this one, I guess I should search for help from internet first, if it does work out either, then I will have to fix it in a local shop. So anyone who happens to know about this stuff, can you please help? 

Brief Introduction to TROJ_CRYPTFILE.SM

TROJ_CRYPTFILE.SM is a new Trojan and also a potentially malicious program has been spread on internet for a while. This one mainly disguises itself as normal software in some unknown website or third-party download resource; it can be installed through a download manager. Normally, innocent users whose computer were infected by TROJ_CRYPTFILE.SM would not notice that until they find their computer system acting funny, most of them will be shocked when the find already messed up their computer, because the thought they did not do anything before, they will never allow a program like install in computers. Well, actually this virus is very tricky, in some ways; it can bypass the permission from users and perform some action to harm the system without letting computer administrator know!  

Once mounted, the creator who made such pesky malware will give instructions to it, for example he would like to use a Pay-per-install scheme to deploy it more rapidly, after that, I may tell you this is the beginning of the nightmare, that’s a misunderstanding when people think all the damages were caused only by one virus, the method doesn’t only load TROJ_CRYPTFILE.SM; it may also distribute malicious programs like toolbars and home page hijacker together etc. I will personally take hijacker as a example, for people who don’t get to know what’s hijacker, it’s virus which could totally mess up all your explorers, such as Internet explorer, Firefox, Google chrome and so on, when you open up them, you’ll find the homepages had been changed, all the favorite site you saved early were gone, and you can’t change them back or control you browsers at all, the function keys are failure to use. I think this one already can drive some of the victims nuts, can you image if bunches of unwanted programs running in your system, and you don’t even notice that, cause all of them will be running in the back ground, that’s why their computer will act such weird, poor performance. The malicious program already taken up nearly all of the room of cpu usage. If an infected computer will keep running like this, the overload operation may probably lead it to a blue screen!

What’s worse, TROJ_CRYPTFILE.SM will also attempt to encrypt your files and then try to contact you to bribe you to pay them to release these files. If you are smart enough, then you will not pay for this scam and try to get rid of it at once. However, I still have to remind all the victims; do not treat this one as a small problem just leaves it aside, because cyber criminals may already get their hands on your private info and data, and depend on how value of the info and data, the bad guys will make use of them. So, this whole thing will not only injure the computer systems, but also could harm victims in spirit. No matter what, act quickly to remove this virus would be the best choice.
