made the mistake of turning off windows defender and putting avira on my computer. Tried uninstalling avira because it froze up, now when in the program area to change or uninstall programs there is still an avira icon showingand wont uninstall. tried to get defender turned back on and a window pops up telling me the app is turned off,when i went to acton center and clicked antivirus programs it says turn on defender but doesnt really turn on. any help would be great !!!!!
