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.

Microsoft Security Essentials is set by default to run every Sunday at 2 a.m. Any time the computer is not on then the scan will run the next time the computer is started. The scan time can be altered to suit the user of course. As I noted above the program updates automatically too. Nothing to do except on occasion make sure the program is still running and updating, I have been very happy never had an issue with the program myself

With the wealth of programs for internet security it is about the same as picking Ford, GM or Chrysler as a best vehicle. There are a number of long running anti virus and malware programs that stand up very well. Normally I tend to shy away from the new guy on the block. Note above that Jane_ny uses Live Onecare and seems very happy, I have used and worked on computers that use Windows Defender. This appears to be the best of both. The firewall should not be an issue, it has been used on all Vista models and there have been no big write ups about it being defective. Note too Mikie has been using this since beta and if my memory serves me he mentioned installing this back in the spring or early summer. Like Zep I installed it on my Windows 7 computer just today so I will see what it does for me.
