Security Tool is a rogue anti-malware application that appeared in the fall of 2009. It is closely related to System Security and Total Security 2009, and it is most likely from the same creators.

How Security Tool Behaves

During the first year of its existence online, Security Tool relied heavily on getting people to download its program voluntarily. Typically, what happens with this method of infection is that you get a pop-up message on a website that says your computer is infected with viruses and that by clicking on the window, you can get a free system scan or download a free anti-virus software. Clicking on this window leads to a website with a fake ad for the fake Security Tool software, after which you are able to download Security Tool. Only afterwards does anyone who falls for this realize that they have downloaded something malicious.

Less commonly in the early stages of its existence, Security Tool was also spread by a Trojan that would be hidden in a fake update or bundled with some other download. As time has gone on, Security Tool has been spreading more and more through Trojan infections. In October 2010, it was reported that Security Tool was spreading through fake Adobe Flash Player updates and that this method of infection began with adult websites in Poland.

Security Tool engages in some relatively common scare tactics to get you to believe you must pay for its "full" or "updated" version. It will configure itself to run on startup, so that as soon as you begin Windows the first thing you see will be a fake Security Tool "system scan" window. Security Tool will start running a fake scan and claim that your computer is infected with 41 viruses. (For some reason, it always tells people this same number, 41 viruses.) Be careful here, because the things that Security Tool picks out as viruses are actually just Windows components, and deleting them can really cause problems.

From the main Security Tool "scan" screen, there will be options to buy the full version or to update the software. If you click "update," it will show a progress bar, but there will be absolutely no actual activity or communication over the network that would correspond to an update. It's all for show. Security Tool doesn't actually have the capability to protect anything. It just puts on a show to scare you into thinking you have to buy its software. Some of the other things that it does include preventing other programs from running and claiming they are "infected," creating extremely frequent pop-ups that warn you of phony urgent security issues, and sometimes even interfering with your ability to access the Internet.

Remember that you do have a choice, and you don't have to pay money to the scam artists who created System Tool. Paying for System Tool will not change anything, and contrary to what System Tool wants you to believe, it can be removed.

Security Tool installs on your computer through a trojan and may infect your system without your knowledge or consent.
