If you are seeing a message that says you are infected with Lsas.Blaster.Keylogger, then you should seriously consider investing in a reliable antimalware program, because this message is sent by a fake antivirus program called System Security. That is to say, Lsas.Blaster.Keylogger is not a real infection. The name is used to create a fake security notification that would later on push users into purchasing System Security or any other rogue from the same family. Therefore, the answer to this program is rather easy – in order to remove Lsas.Blaster.Keylogger, you need to remove System Security in the first place.
The fake antivirus program System Security was first detected in 2008 and all the bogus messages distributed by this application include the names of non-existent computer infections (such as Lsas.Blaster.Keylogger). It also claims that a number of system files are infected as well, including svchost.exe, which is actually an important system file that runs almost all of the time. Actually, were you to listen to System Security and delete svchost.exe you would not be able to run your PC properly.
Therefore, you have to ignore all the fake security alerts delivered by System Security, including the ones that say you are infected with Lsas.Blaster.Keylogger. You are definitely infected with malware, but not with the one you are being told about. System Security (or System Security 2009, depending on which version you are infected with) is a dangerous threat itself, because it significantly slows down your system, constantly performs a fake system scan and then pushes you into purchasing the full version of a dysfunctional program.
According to System Security, once you invest in a full version of this application you will be able to remove Lsas.Blaster.Keylogger and all the other reported issues. However, were you to reveal your credit card date in the rogue’s purchase form, the cyber criminals behind this scam would gain access to your bank account and your money would be stolen.
Therefore, in order to get rid of the Lsas.Blaster.Keylogger fake security messages, you need to invest in a powerful antimalware tool and remove System Security from your computer. The problem is that most probably you have other dangerous threats in your PC as well, so run a full system scan with SpyHunter free scanner to figure out what other unwanted programs you need to remove. Once you have that settled, acquire a legitimate antimalware application that will protect your PC.
