Here I will explain the way to prevent virus and malware from entering your computer:
1. Anti-virus, yep that's the most important part of your computer, no computer can stay safe without that. There are a lot of good and free anti-virus out there, you can search it or just click here to download my recommended anti-virus. Only installing anti-virus isn't enough, you have to update it everyday (some anti-virus automatically updates every hour). Don't forget to always set the realtime protection on (it will slow down your computer a bit, but without realtime protection the anti-virus is useless).
2. Anti-spyware, also important to prevent your computer being 'infiltrated' by uninvited guests. So what's the difference with anti-virus? Anti-virus kills virus that will try to destroy your system, while ant-spyware prevents spies from stealing informations on your computer. Anti-spyware can be very effective to protect you when you're browsing harmful websites because those websites probably send you things that you won't like (keylogger is a good example). There's only a little number of good quality spyware killers, so I'll recommend one for you, click here and don't forget to update it at least once a week.
3. Firewall, virus will try to download its "friends" when active, prevent it by firewall. Firewall can also block network attacks and cancel harmful downloads. Windows firewall isn't enough, you need stronger firewall, you can find a very strong one here. Firewalls usually updated only a few times a month. Each time it gives you warning about connection attempts, check the process name, if you think that it's suspicious, then deny the access.
4. Startup manager, this the part that underestimated by many people. This one is your last defense against virus and malware. If the virus or malware can't be stopped by anti-virus, anti-spyware, or firewall then you have to stop it yourself. Every virus and malware will always put themself in windows startup. When you see suspicious file trying to add itself to the list, you can block it using this software, click here to download.
