Good evening everyone. I would like to get some opinions on this, how to keep my PC in top shape? Several months ago, I had a browser hijacker on my PC called Ueep, and that was extremely difficult to remove. It remained on my PC for 3 months and I managed to get rid of it last January. It took 12 hours to remove using several programs. I am so glad that it is gone now, but I would like to know, does it really make sense to install programs such as Iobit's Advanced System care on my computer and Iobit's Smart Defrag on the computer or is it best to use the free utilities that come with the windows operating system (Windows Defragment and Disk Cleanup)? I am just afraid, if I begin experimenting with different programs, would I run the risk of bringing back that browser hijacker or any other problems that was so difficult to get rid of. Right now, my PC is running fast and fine, but I would just like to know, is it really worth downloading those 3rd party programs or are the built in programs for Windows fine for keeping my computer clean and optimized?
