Computer Threats

One of the most annoying factors about the Internet is indeed Pop-up ads. They often interfere with your web surfing and searching. But, compared to junk e-mail, they are considered a minor threat to you and your business. Employees that download programs to work computers can also cause these threats.

Viruses and Spyware – a computer program that can copy itself and infect a computer. Spyware can enter a computer system through infected e-mail messages and can secretly monitor what employees type and record account numbers and passwords. Security holes are other ways for viruses and spyware to enter a computer.

Adware – Similar to spyware, adware installs itself on a computer. Even though it typically displays more advertisements as usual when online, it can cause your computer to slow down. Adware does not destroy data.

Create a security policy that clearly state what employees can download to their office computer, and what they cannot. Explain in person to employees why the policy is important.

Consider using software that checks for and removes spyware. Microsoft has a free Windows Antispyware program and a Malicious Software Removal Tool you can use to rid your PCs of unwanted software.

Use a firewall on your PC and a router for network protection. The combination of activating the built-in Windows Firewall and adding a network protection device enables you to filter or block Internet traffic to and from dangerous sites.

Make sure your antivirus software is up-to-date and that you use it often to thoroughly scan your system. If antivirus software was installed on your new PC for a trial period, make sure to buy a subscription after the period expires, or buy and install a new antivirus product.

Regularly check with your software manufacturers to make sure you have downloaded and installed the latest updates to patch security holes. If available, use an automatic update service like the one available with Windows XP.
