Download HijackThis. Unzip it. Run a scan, and save the log file. Copy and paste the log file, along with your problem, into a new thread on the HijackThis Log Help Forum (not this forum). The analysts will scan your log file to check for any malicious programs running on your system (viruses, trojans, worms, spyware, etc). If anything is found, they will provide you with steps to thoroughly cleanse your computer.
Open Control Panel. Go to Security Center. Click Firewall. Go to "Recommendations". A dialog box will pop up. Make sure there is a check in the box below that says "I have a firewall solution that I will monitor myself". Do the same with Virus Protection.
