Typical problems on today's personal computers include disorganization, malware, spyware, and loss of privacy from intrusions by outsiders. To address these issues, users can clean up their computer with free utilities, use free anti-virus and firewall software, and ensure all software is updated and patched. Leaving a computer unprotected can result in slow performance, pop-up ads, spam, and other issues as unprotected systems may contain hundreds of spyware components and other malware.
