No need to apologize. We're always glad to help. It seems a bit odd that a standard Windows Vista logo was superimposed on one of Dell's. It is always good to be suspicious when it comes to the internet. It still wouldn't hurt to run Malwarebytes Anti-Malware. It's free and a good program to keep updated and run every so often just to be sure nothing has sneaked by your anti-virus and Windows Defender.
About a month ago a virus entitled Security suite started attacking programs on my computer. It appeared as an orange logo on the bottom right hand tool bar. It started interfering immediately and gradually got worse. In desperation I finally opened it and had a web site trying to sell me anti-virus software. I managed to get rid of this nuisance by using system restore. Now I have blue logo in the same place which has an i in the middle. When I pass the cursor over it it claims to be "informational alerts" a piece of grammar which makes me think it is probably a virus. I don't think it has done anything yet, although for some reason my screen resolution changed recently and had to be changed back. I haven't opened it. Question is-is it a virus? If so what can I do about it. I tried system restore but it did not work. If it is not a virus what is it?  
virus or not?
