My aunt's computer is super slow. She's had her dell computer for about 4 years now. Her daughter and nieces put a lot of little games like dinner dash and some casino like games on it. Also it has McAfee anti-virus program that came with the computer, but it has been expired for a couple of years now. I was thinking about putting AVG anti-virus the free version on her computer because the computer hasn't had a virus scan in a long time. It take like 10-15 minutes for it to go from the profile screen where you choose which profile to go under to the actual desktop. From the desktop everything is still slow, it takes forever sometimes for it to do anything like clicking on an icon. Sometimes you will have to put the mouse cursor on an icon and then press enter for it to do something. I installed malwarebytes and did a quick scan and it found like 425 problems. I thought that would fix it but it's still slow. I am in need of some help big time, so if anyone has a solution to this disaster please let me know thanks in advance.
That sounds like a classic, spyware filled computer to me. You really need to download and run anti-spyware/virus programs. When you ran malwarebytes, did you actually tell it to remove the infected files? I'm not familiar with the program, but I use spyware-terminator/ad-aware and AVG-Free with great success for these sort of problems. Once you have these installed you should boot the computer in safe-mood by pressing F8 at the boot screen and then running the scans. It should make things run a lot smoother.
Try what delta36 has said, also try cleaning her temp internet files with ccleaner and do a disk defrag. Here is a link for ccleaner http://www.ccleaner.com/download Hope this helps
Yeah when I ran malwarebytes, I told it to remove the infected files. I will do what you said and see if they work thanks.
