Thing you must do to keep your PC Safe
1. Run Windows update often. It should be ran once a week . It is very important to install all critical updates on your PC in order to patch any security holes found in Windows.
2. Install and update an Antivirus program on your PC. I have used several over years. My favorite is Norton Antivirus and PC-Clins Antivirus programs. I suggest that you download and AVG Antivirus if you can not afford to buy an Antivius program. Do not open attachments. If you have to open an attachment do the following: find out if the the person that sent it meant to send it, and you scan it
3. Scan for Spyware and Adware. This type of software also needs to be updated. The program I highly suggest is Sybot Search and Destroy. Another program is Ad-ware. To learn more about Spyware / Ad-ware check out my aricle Spyware What is it and how to get rid of it .
4. Install a firewall. Get a router if you share your internet access. If not download the free version of ZoneAlarm. Having a firewall is very important, because it helps to protect your PC from viruses, and other forms of hacker attacks. A firewall is no replacement for any Antivirus and Spyware / Adware detection software.
5. Use a tough to crack password like !Qas5*9n? not Muffin to protect your PC from being cracked into. A good password also applys to every thing that requires a user logon like email, and a router. Also remember not to share your password with any one. I highly suggest that you change your password every 90 days.
6. Protect your PC from power problems by doing the following. turn off and unplug your PC when a thunder storm hits. Use a UPS to protect your PC from power spikes, brown outs, etc. UPS also allows you to save your data and shut your PC down safely if the power goes out. An UPS works by getting power from the wall socket to charge up a batterry which powers the PC. If you can turn off your PC during a thunderstorm to protect it from harm.
7. Use a different browser instead of Internet Explorer. The reason for this is because of all of the security vulanabilities found in Windows. I highly suggest Mozilla's FireFox, which cuts down on the security fauls found in Windows, and also offers many great features like: tab browsing, and popup blocking.
