The problem is not that your system cant carry out simple instructions without going on a pilgrimage. It is not that if you as much as shift the mouse key, an alert/warning comes up telling you how a program was stopped because they couldnt verify its source. The problem could be that you system has been taken over by Antivirus.NET virus.
Exactly. The Antivirus.NET virus is a virus that sounds, looks and feels like a real Anti Malware Application. It is so successful at this that many took to it from the word go. And they paid the price for allowing image to rule their decisions.
Cause and effect:
It does not just slow you operations down; it also does some potentially more damaging things like pass on your credit card information to its creators and other relevant details. Your system becomes a shadow of its former self as it can hardly be used optimally. Antivirus.NET virus effectively becomes the application determining what other applications can do and how they can operate.
This was set up from the very onset with their marketing strategy of first telling you what is wrong with your system and offering to have it rectified for free by downloading their anti virus software at no cost to you. Downloading becomes hard to refuse but unknown to the person doing the downloading, rather than download an anti malware, they downloaded a dreaded malware, the antivirus.NET virus.
You can get rid of this malicious scarware by editing the system registry to stop the virus from loading at startup and then deleting the infected files. The only little thing you should be careful of is that you would effectively render your system impossible to use if you as much as tamper with some other files in that registry.
