Spwareblaster would be fine to install and a good idea. Along with a program called Web of trust (Wot) These programs actually can prevent Malware from installing in the first place. Only run 1 Anti Virus Program. Only use 1 Firewall. And only 1 Active Spyware program, like Windows Denfender, in your case Kaspersky probably covers you as it would more then likely have spyware protection and a firewall included. Spywareblaster does not scan in the background so it will never interfere with any other active spyware programs running. You will need to up-date it manually, I check mine once a week. Malwarebytes free will also never interfere with other active scanners, it's called an on-Demand scanner and does not run in the background and does not prevent malware, it is generally used after the fact to remove malware. Malwarebytes is the first tool of choice to use when you think you may have an infection or just addware like myweb search, or the ask toolbar.

Windows Update had nothing to do with it. You may have accidentally downloaded it to some other location on your computer. As long as you didn't interrupt the download, it should be there somewhere. If you try to download it again, pay close attention to where it says it's going to be saved. For reasons too complex to explain, downloads can go to different locations; you can always change this before the download starts, but you should never assume a download is going to the "usual" location. You need to carefully check the download location before clicking on the save button.

it sounds like you have an infection that has blocked you from getting programs that would try to clean it, see if it lets you go to any of these online scans to run.

The default settings are the ones that the application comes with. If you haven't used it in some time, it will probably tell you there is a newer version. Download and install the latest version and use it without fear. Like azinoh I have used both the clener and registry tool with no problem, always backing up the registry. This is just one step in my routing maintenance before I defrag.
