If your system's getting those, your security measures need an overhaul immediately :shocked: Are you using WindowsXP? If so, enable the Internet Connection Firewall right away. Start > Control Panel > Network & Internet Connections > Network Connections. Now right-click your network connections, choose
Properties, hit the
Advanced tab, and enable the firewall on each connection.
If you get lost, consult Windows Help on the Start menu and search for "Firewall." If you're
not using Windows XP, then get some other firewall software installed, such as
free ZoneAlarm.
Next, order up a budget router (assuming you have a broadband internet connection). Linksys BEFSR41, D-Link DI-604, Netgear RP614, those would be fine.
More info about routers and how they protect you.
After that, get some
current antivirus software installed, trialware at least, update it, and scan for viruses. Get
Microsoft AntiSpyware beta and scan for spyware.
Once you're clean, update your computer at
Windows Update and keep going back until it comes up clean there too.
