Keeping safe on the Internet can be a very difficult task. There are a lot of threats to your PC out there, and it can be very hard to keep your computer clean. One of the more infamous threats nowadays is the appearance of fake anti-spyware programs.
These pieces of malware pretend to be legitimate programs to defend your computer but are actually malware themselves. A prime example this is AVDefender 2011. Usually, trojans and fake online scanners promote this AVDefender as a way to keep your computer safe. If you didn’t know any better and downloaded it, you’ll be in for a lot of problems.
First of all, it will change your security settings to block legitimate anti-virus programs. This is to protect itself. Next, it will modify your settings so that it will always activate on start-up – where it will do a fake scan for viruses. This is fake because these infections do not exist – they’re just made up so that you would pony up the cash to buy the “full” version of AVDefender to remove these infections.
If you have this program on your system, be aware that it is malware and that you should remove it immediately. To find out what to do, read on.
