How to Deal with an Ongoing Attack

The first thing to do if your PC is under attack is to stop the attack. You can do this by disconnecting your computer or network router from the Internet, which should terminate the attack.

Once your PC is offline (disconnected from the Internet), you should use your anti-virus software and anti-spyware software. The anti-virus software will run a scan to look for any backdoor Trojan programs installed by the intruder. You should also look for any missing or changed files on your system. Upon successful completion of this activity, you can then reconnect your PC to the Internet.

Once you're back online, you may find that your PC is still being attacked. (This is possible if you're the victim of an ongoing denial of service attack.) If this is happening, disconnect your PC from the Internet again and then contact your Internet Service Provider and alert them of the attack.
