Earlier this year, my computer got infected with Vista Guard. I downloaded the free malwarebytes to remove it and that appeared to work, but it re-appeared this past Monday. This time around, it wasn't as bad since I could actually open my programs around it, but I still wanted to remove it. For some reason, Malwarebytes wouldn't open, so I went to MajorGeeks and downloaded a-squared, their top anti-virus freeware. Apparently there has been some kind of change in business with that company because it changed into a different program mid-download, but I looked it over and it all seemed legit. I let it go and finished the download. The a-squared did remove three files, one of which I assume was the Vista Gaurd because it hasn't shown up since, but now I have a bigger issue. Ever since the download, many of my programs do not open. Instead I am asked to pick another program to open the file for the program I want. And with every attempt to open a program, I am also asked to pick an additional program to open another file, that I don't even recognize. This additional file is any of these 3: MSASCui.exe, ssvagent.exe, and rstui.exe. ssvagent is by far the file that pops-up the most often. Because of this, I cannot open many of my media programs and the ACER empowering technology no longer loads on start-up. (Oh, I have an ACER Extensa 5420) There is one other little set-back to the problem. I do not have access to everything on this computer, nor do I have all the paperwork. It was donated to me through a third-party, and the man who gave it to me got it me did not give me all of the information. I only know that it was set-up through geek squad. He even has programs on here that are password protected, and he didn't give me the password, so I have been kept from different areas of the computer based on that. Ideally, I can fix whatever is going on with my computer without paying anything. I plan on buying a new one in Feb or March and I don't want to put any money into something that I won't use for much longer. I don't have the money anyways. Oh, and I can't give my specs either. This 'pick-a-program' issue wont let me use download from online, and all of my Windows related activities keep giving me an 'application not found' box. Please, if anyone can help me I would really appreciate it.
