If your computer has limited resources, you might do some research on it and see if it could be an option. The computer I have it on has not suffered any problems, but my actual usage of it is probably less than a year. I keep meaning to set up a virtual PC and do some rigorous testing, but I haven't had the time. For that matter, Panda Anti-virus is cloud based and has a very small footprint ( ) but I have not used it enough to vet it properly. For a good number of years I have used Avast for antivirus ( ) There are a number of good free AV programs, but I've found Avast works well for me, and does not have a large system footprint like others do. I routinely scan my Add/Remove programs list for anything I missed or for programs I just no longer use. I use extra caution when I am installing a program, to make sure there are no tag along programs being installed as well. Such 'bundle ware' is common, and while not usually nefarious or harmful, can load up a PC with useless junk. often a tool bar or other such app will be installed with another wanted program without your knowledge. Like others have said, most computers have programs on them the user never needs. If you have never used such programs on your system, the first time you run them you will be amazed at the junk they remove, and the space freed up. I recommend using CCleaner in conjunction with Wise Care as it gets some detritus that Wise Care doesn't. I use the Pro edition, but the free edition is pretty much the same. I also recommend Wise Care 365 as I have used it extensively on three computers without issue, and I have been pleased with its performance.
