Disabled software and settings

When configured correctly, your anti-virus software should launch automatically each time you start your PC. It also should look for viruses in every file you open or save, every email message you read, and every web page you visit. You should become a little nervous if you notice that the anti-virus utility suddenly stops doing these types of things and you know you didn’t disable the software yourself. Some of the most recent viruses can now disable anti-virus software and spread themselves without detection.
In addition to disabling the anti-virus software, viruses also may disable firewalls and reconfigure key system settings. The only way to recognize these changes is by paying close attention to system performance.
