Never respond to SPAM
Don't even click the alleged "unsubscribe" link (it won't unsubscribe you!) It encourages the spam-makers to continue sending spam. It also lets them know they've found a "live" address, and consequently your address will then be sold to hundreds more spammers. The best way to deal with spam: use a program such as IHateSpam, or simply delete it. For more help with this problem, call On-Site Solutions today.  

Don't fall for "phishing" scams 

Have you gotten an e-mail from Such-and-Such Bank, titled "Important Online Banking Alert"? Did it ask you to "confirm your bank account records" by clicking a link? But yet you have no account with that bank?! That's because someone is "phishing" for customers of Such-and-Such Bank. Don't be fooled... never divulge personal information such as passwords, PINs, or account numbers over the Internet. Call your financial institution if you have any questions. 

Ignore Pop-Ups 

Pop-up messages are not just annoying, they can be hazardous. A click on a pop-up window may start a file download, with or without your consent. Be especially cautious of pop-up windows that simulate legitimate windows from your operating system (ie. "WARNING! You may have critical errors on your PC"). Close these pop-ups by carefully clicking the "x" in the uppermost right corner (sometimes there are two, to deceive the user) or use the keyboard combination of the alt and F4 keys.

Turn off Preview Panes in Outlook and Outlook Express

With the advent of VBScript-based viruses being spread by e-mail, it is possible, with Preview Panes on, to launch a virus as soon as you receive the e-mail. To turn Preview Panes on or off in Outlook, click the View menu and Preview Pane. In Outlook Express, click the View menu, then Layout, then click the Show Preview Pane checkbox to deselect it, and then click OK.

Protect removable media - Zip and Floppy

Scan all zip and floppy disks prior to using them. When moving a disk between computers, ensure that it is virus-free and copy-protected before putting it in the next computer. This prevents the spread of viruses. Note: Viruses can also be spread via CDs... ensure your files are virus-free before burning that CD!
