So I got McAfee then later a downloaded something which gave me random stuff on my computer so I recovered it. I then tried to get McAfee again but then after I installed it I could not open it and it would not appear in the task bar. Hold on it did open yeah but I could not do anything with it and also I pressed scan and nothing happened. Also yeah the McAfee thing was not on my task bar. Then I saw other people post similar comments and a person had a link to a technical support thing so I did it and then it said I had 4 missing files, that was a problem that could not be resolved and I also scanned it again and again but the 4 missing files thing could not be resolved, but I do not understand what that means. Then I restarted my computer. McAfee was in the task bar but it will not open. Please help me.
