If you’ve got a PC infected with malware, spyware, or rogue/fake antivirus applications, the best tool for removing them is the free SUPERAntiSpyware Portable edition.
You might wonder why a portable version is so important… the problem is that the worst malware infections block you from installing malware removal software, and even if you manage to get it installed, most of the time when you try and launch it the infection will not let it.
So this edition does not require installation and will run from a memory stick if nneds be.
