Keep your system updated

• Keeping your programs (especially Adobe and Java products) updated is essential. Update Checker will notify you if any of your programs require an update.
• Microsoft releases patches for Windows and Office products regularly to patch up Windows and Office product bugs and vulnerabilities.
• Please ensure you update your system regularly and have automatic updates on. You can learn how to turn Automatic Updates on here

I also recommend you to switch your antivirus program to a better one. Here are some suggestions:

• avast! 7 Home Edition - Don't use it with Online Armor
• Avira AntiVir Personal
• Microsoft Security Essentials

In addition to your antivirus, you need additional protection such as a firewall and behavioural blocker.

• Online Armor
• Comodo Firewall - If you are an advance user

Here are only a few suggestions that will improve your system security. Should you wish to allow us to make full recommendations and set your PC up with maximum security, please start a thread here. Our community of PC enthusiasts and experts will give you feedback and help you secure your system from future malware infections.

Internet Explorer may be the most popular browser but it's definitely not the most secure browser. Consider using other browsers with addition add-ons to safeguard your system while browsing the internet.

Firefox is a more secure, faster browser than Internet Explorer. Firefox contains less vulnerabilities, reducing the risk of drive-by downloads. In addition, you can add the following add-ons to increase security.

• KeyScramber - Encrypts your keystrokes to protect you against keyloggers that steals personal & banking information
• AdBlock - Disable/blocks advertisements on websites so you won't accidentally click on a malicious ad.
• NoScript - Disables Flash & Java contents to avoid exploits or drive-by attacks
• Web of Trust - Shows the website rating by other users and blocks dangerous and poor-rated sites

Google Chrome is another good browser that is faster and more secure than Internet Explorer by having a sandbox feature. Additionally, you can add the following add-on to Chrome to heighten security.

• AdBlock

Lastly, it is important to perform system maintenance on a regular basis. Here are a few tools and on-demand scanners that you should keep & use every 1-2 weeks to keep your system healthy.

• CCleaner
• Malwarebytes Anti-Malware
• Temp File Cleaner by OldTimer

Other than that, stay safe out there! If you have any other questions or concerns, feel free to ask
