Hi, having a bad day, i turned my pc on this morning to find it was infected with security tool malware, its the worst of the type of those that ive had so far. I just got it cleaned out though, at least it appears to be gone for now, i couldn't get any malware removal tools to install, was tryng a few but whoever programmed security tool are crafty enough to try and block you at every obvious attempt. Anyway, il provide the link to the info below because this is the worst one ive had on my pc, at that site search for the name Stephen and follow his instructions http://www.xp-vista.com/spyware-removal/remove-security-tool-removal-instructions i noticed how after he posted his solution, that a few people were satisfied with the results, its a manual removal, but doable, just take it nice and slowly. One thing ive noticed when looking through suggestions on sites on getting rid of malware is so many different suggestions and it gets confusing, not knowing what to try first, if you try his numbered instructions though you should be ok, and hopefully it works for you too if you ever get this dreaded infection.
