... I've had several incidents of trojan horses getting through (on my computer and others), and a few weeks ago, AVG mysteriously uninstalled itself from my computer.Apprently something got though to allow it to do that.
If you ask me, the process starts with something FREE and has nothing to do with your Free Antivirus.
Usually, you have to click OK to something, like download a Free game or (my all time favorite) Free Screen Saver, or it find its way into security holes in applications, like in Widows or Flash Player. This comes with Malaware (not a Trojan) that plugs itself to the Registry file.
From there, first thing they do is to Turns OFF (changes the value in Registry to prevent starting) your Antivirus program along with the Firewall.
Then, they do whatever they want to do, starting from displaying bunch of warnings that you have crap load of viruses and they recommend to download a software to remove them (with or without pay), or by simply installing back door Trojan that the only purpose of it is to let other Trojans in.
BTW, I havent seen Antivirus software get uninstalled yet, its deactivated and hidden.
And Malaware is not a virus; Antivirus will not detect it on download since mostly it happens with your permission. For example, from simple please vote to , click OK to download and to see this nude picture please confirm that youre over the age of 18 years old
My vote goes to Avast Antivirus software, I use it and recommend all the time. And set Windows updates to Automatic.
