you would only have MSE if you went and downloaded it and installed it, the program does NOT come with windows. You would need to totally remove AVG when and if you do get MSE, as stated use the removal tool which you can find here. Antivirus Product Removal Tools Keep malwarebytes if that is actually what you have, it is difficult to know when you do not use the actual names in your post. What does this line that you posted mean??? "the malware small window at the bottom of my screen" are you referring to malwarebytes? or is it some rogue malware??? Tell us exactly what it is you see and what it goes to. Names of security programs are extremely important because the people that want to infect your computer with bad stuff create the bad stuff and put names on it that are very similar to real programs and if we do not know which you have well we can't really help. And zep is right the mini is not really meant to be a main computer it is small in every way not just size, it has a very small processor and since yours runs windows 7 it takes a lot to run that and the little mini will struggle. but you do need to tell us exactly what is slow, is it surfing the web, is it booting up, is it opening programs on it????

since you said you don't know anything about it then I would run a belarc to get all the info about the pc and a SIW, plus you will want to run a secunia scan to see what needs updating on it and do those asap. Belarc Advisor SIW those are good to print so that you have all the info handy should you need it. Secunia Online Software Inspector (OSI) I forgot to mention adding spywareblaster to your security list, just install, update then once a week open it hit update then click the enable all protection so the shield turns green. SpywareBlaster be sure you get the free version when you go to the download link just continue with the one you started with do not move to the trial of the pay version.

Thanks, Zep and Raven. I had a hard time finding the free ZA download, but managed to avoid the other stuff in the end. Oh, yeah, and I can see that ZA is going to take some getting used to. Lots of things in Program Control that I don't know what to do about, though when I can find time to go through all the tutorials Raven gave a link to, I hope I will begin to understand. But meanwhile: (1) Will Firefox need to be "allowed" under "Server"? If I don't allow it, what might I miss out on? (2) Should I allow Sys32\svchost under both Access and Server? I have no idea what it was allowed previously, though presumably access was allowed. (3) Under Firewall>Advanced, I find "Disable Win Firewall," which I assume is good, now that I have ZA, but what is "Filter traffic over 1394"? No idea at all what 1394 is or what checking this box might do. Only these two boxes were already checked. I will leave them checked until I hear to the contrary by one of you. All help along this line is appreciated!
