Question:How do I uninstall illegal software?

Spyware and malware infections are incredibly frustrating for any computer user and can dramatically decrease both system stability and performance. Thankfully, detecting and removing these irritants is fairly straightforward. If you think your system has been infected, follow these steps:

1) Download and run the Microsoft Malicious Software Removal Tool. This will scan your system for a number of common viruses and inform you if any are present.
2) Once this program is finished running, visit the Ad Aware website. Ad Aware is a free utility designed to clean spyware and malware installations off your computer.
3) Install and run the program. You may want to run it several times to ensure all malicious software has been removed.
4) In order to keep your system protected in the future, consider purchasing Ad Aware or another anti-malware product, such as Spybot. Companies like Norton and McAfee also include anti-malware software in their security suites. If you need an anti-virus solution as well, one of these might be a good option.

Successfully completing these steps should result in an malware-free computer.
