My inlaws' desktop pc was hit by a this a virus that pretends to be anti-spyware programs. Their names are kinda legit but they are just scarewares. Their computer's antivirus expired and they thought those pretending to be anti-virus scanners are ok so they downloaded it saying that it's free for trial. The rest is history, their computer is now infected. As I googled about this, I found out that these pretending / fake anti-virus programs once installed starts the infection and once it's running on your computer, it will install another copy of itself with a different names. Some of the rogue names for Windows 7 are Win 7 Antispyware 2012, Win 7 Antivirus 2012, Win 7 Home Security 2012, Win 7 Internet Security 2012 and Win 7 Security 2012. The latter was the one that kept on popping out their computer screen prompting you that your trial copy is already expired so Renew Yes or No? Then a blackscreen, wait for a couple of minutes, it will back to seemed normal, then it goes on and on. I will be coming to their house to fix their computer, since it's spring break, I could bring along my son and will have enough time to troubleshoot. I thought it would just be simple based on my background about this stuff but when I googled it, it's a long process! There are lots of things to download, which I'm having second thought of downloading them. There are lots of files to backup because it will be a nightmare when one day, they will ask me for a certain file that's not really existed. So, I need a backup to show them that those are their recent files and documents. Lots of programs that will be reinstalled if the need arise that I should wiped out and have system restore. Moral lesson, don't procrastinate in getting your anti-virus, always makes sure before the expiration, you already renewed or bought and installed a new one from legit distributors. For me, I always want the disc copy and not the downloaded one. Goodluck to me and I hope things will work as it should be.
