How do I get rid of pop-ups, viruses, adware or spyware?
If you suspect that your computer is infected with a virus or other malicious software, remove it as soon as possible.
Unlike other software, malware can't be completely removed by using your operating system's feature for add/remove programs. Some bits of malware may still be hiding on your hard drive, doing damage behind the scenes. To remove malware, use software specifically designed to find and delete it.
Many solutions are available for ridding your computer of malicious software. Find these programs by searching the Web for virus protection. Whatever software you choose, be sure to keep it up to date.
In some extreme cases, antivirus programs may not be able to remove all malware. It may be necessary to reformat your hard drive and reinstall its operating system. If you're using a laptop computer, installing the operating system from the partition backup may not completely remove malware. Instead, be sure to get installation disks for your operating system from your hardware vendor, and use them to reinstall your operating system.
