My English classroom has a lot of computers, all of which are very slow due to not being maintained and old, outdated software... or even software that is redundant. One of the computers has three antivirus programs, Adware (freeware), Symantec Endpoint Protection, and Microsoft Security Essentials. Are all of these needed? Symantec comes on every computer in the school, and removing it is not an option. It detects a lot of viruses (I have had things such as NetCat on my flash drive that it picked up), and I do not think they would like to stray away from this.
Is it possible to delete Adware and MS Essentials, because they are just doing the same thing? I would replace the both of those with MalwareBytes Anti Malware, which I have never used, but have read a lot of good things about.
Basically, is it OK to remove Adware and MS Security Essentials and keep Symantec Endpoint Protection? And is MBAM really needed if Symantec is in place, or even recommended by you all?
