Is there any Anti-Spyware programs that are really good but totally free as well. I have already downloaded several Anti-Spyware programs but when i have scanned my system and it has found several threats then after it i try to remove them it prompts me to buy the full version and says that i cant remove any threats until i buy it, but to be honest i don't really have the money, so is there any way of me getting a program that is absolutely totally free and is good quality.
Also, my Windows Defender and Windows Firewall is not working, once i click on either of them my computers say that the service is not working properly and i should restart my computer. But, i have done this several times and nothing has changed. There is also a code included within the message when i try to open Windows Defender the code is:
Now, i have no idea what this code means and why my Windows Defender isn't working, please could someone help me in solving this problem.
Also if this helps i am using Windows Vista Service Pack 2.
