It seems that you think this is a virus, although there could be other causes for your Internet to be periodically disconnected. We’ll address the virus issue first, and if that doesn’t work, you can try some of our other suggestions.
Antivirus Programs
The first thing to try is the Microsoft Malicious Software Removal Tool, which is available for download here: http://www.microsoft.com/security/malwareremove/default.mspx . I’m assuming that you have antivirus and antispyware protection - if so, make sure it is updated by downloading any updates from the manufacturer’s website and running them regularly. If you don’t, you need to get some quality antivirus software. We have recently reviewed about 20 quality antivirus programs. Check out our reviews here:

Modem Connections and Settings
If you run the antivirus programs and you are still being disconnected from the Internet, chances are the problem isn’t a virus. The easiest thing to do is to check your Modem connections and make sure everything is where it should be.
Check your modem settings and update your drivers by going to:
- Control Panel, then double click on the Phone and Modems Icon.
- Select Modem and Click Properties. From here, you can update your drivers, troubleshoot any problems and find conflicts.
- Check to see that your system isn’t set to Auto Disconnect - the computer will come with this disabled, but it’s possible that it was reset. This is located in Advanced. Check the default Preferences and make sure that the “Disconnect a call if idle” is not checked.
If you are having a problem with the modem, you may have to get a new one to solve this problem.
Check Your Router
We actually had this happen to us just last week. Our Internet connection was disconnecting and then reconnecting randomly - I don’t have to tell you how annoying that is. We had our ISP replace the modem, but it was still a problem. We replaced the router and it’s been working fine every since. It is a more expensive solution, so try some of the above fixes first, but it is worth checking into if all else fails.
