Security Tool: what it is, and how to remove it.
If you haven't heard of 'Security Tool', then chances are you soon will. This fake program is as aggressive as any virus, and if your computer becomes infected you're in for a fun time in trying to get rid of it.
Security Tool presents itself as as a bona fide anti-spyware program, popping up on your computer and informing you that you have dangerous viruses. It offers to cleanse your computer of said viruses, and very convincing it looks too (see above). But beware. If you allow the software to perform a 'free scan', then you very quickly realise that Security Tool is the virus. It shuts down all programs other than those necessary to keep itself running, and the 'threats' that it suggests you remove are in fact legitimate Windows applications. Your desktop will be jammed with pop-ups that are simply impossible to circumnavigate. No amount of deleting will get rid of them, and trying to access program removal is useless. Many of the big name anti-virus programmes currently have no defence against this vicious little beast. A member of my family inadvertently allowed Security Tool to run, and I've spent many hours of frustration in trying to deal with the resultant havoc.
Security Tool is a piece of work, sophisticated and cleverly designed. You have to wonder at the kind of person who would put their creativity to such damaging use, and why they would want to be so despised. It's beyond me. But, as always, there are superheroes on hand to vanquish the forces of evil!
So step forward Malwarebytes Anti-Malware. This is one of the few programs capable of defeating Security Tool, and I'm very pleased and grateful to be able to recommend it. Get it now. The free version works fine, but for ongoing real-time protection you might consider stumping up for the Pro.
You'll also want to visit bleepingcomputer.com's helpful site for more comprehensive information, and a step-by-step method for Security Tool Removal. This runs to several pages, so you'd best print them out.
Even with Malwarebytes excellent product successfully installed, you're still looking at several hours work. I had to download the software onto a separate laptop, put it onto a flash drive, and then upload it into the infected computer running in Safe Mode before I could begin. And this is part of the problem - the infected computer will be virtually seized, and so you'll need a second machine to operate from.
The best solution would be to install Malwarebytes in the first place, so if you're lucky enough to be able to read this then I suggest you act now while you still can.
