The following software has been tested by myself and may currently be used on one of my computers at home. I try not to reccommend software to anyone that I have not personally had some experience with.
AVG Antivirus: I dont personally use this program at this time, however i have many personal contacts that have had good luck with it. I have used it very briefly in the past but could not tell you anything about the latest/most updated version.
MalwareBytes: This is an anti-malware program, and in my honest opinion the free version is just as good, if not better than the paid version.
Windows Defender: This program is built in to newer versions of windows, and is also free. It is a very good program and mostly a set it and forget it type from what i have found.
MS Security Essentials: Free antivirus distributed by microsoft in earlier versions of windows. This has since been replaced with Windows Defender in newer versions of Windows.
Spybot Search & Destroy: Be aware that Spybot has a newer version specifically for Windows 10. I personally had no issues with it from the start, but then had some form of conflict with the other programs that i was running, so i chose to uninstall it. Although that is not to say it is a bad program. I have used, and continue to use the older version of Spybot on my laptop.
PCDecrapifier: This can help to remove many "bloatware" programs that come installed on a new computer. BLoatware can significantly reduce your computer's performance in some cases.
CCleaner: CCleaner is a very useful tool as well. I use it often when optimizing my own personal computers.
For those of us who are predominantly Windows users:
Use Windows XP or Windows 7, 8, or 10. Never use Vista.(There is a reason Windows 7 came out, to "improve" upon Vista.)
For those who are wanting to change over to Linux but have little to no experience with it, i suggest trying out Ubuntu. Not only is it free, but it is easy to learn.
Contact me at the first sign of trouble. If you notice your computer being extra sluggish, popups, or other abnormal behaviors, don't hesitate to call.The faster you get computer issues fixed, the less damage can be caused in most cases.
If you dont know exactly what you are doing, setup a consult, and let me help you. Please don’t purchase computer equipment from someone on eBay or craigslist. If the price is too good to be true, it probably is. You never know what you are getting until it arrives. You also dont know the quality.
There is however, some good stuff that occasionally will come up on Freecycle.org, computer related and not. It is sort of hit and miss though, as it is FREE stuff that is being given away and has, in most cases, been "well used".
If you have multiple users sharing the same computer, each person needs their own account with a password.
