You probably have spyware and malware on your computer. Most people do. You get it when you visit certain websites or when you download games and music. The games and music come bundled with a lot of other programs that run in your computer. These programs run constantly on your computer and are difficult to get rid of. They not only serve ads and collect information about you, they can also slow your computer down and cause it to crash.
The solution? Keep your virus software up-to-date and run a few anti-spyware programs. Also make sure your Windows Updates are turned on and working and that your Windows Firewall is turned on. Ducktoes can help. Call (403) 287-0105.
