One constant struggle firms face is spyware, adware and other "malware" infections on computer workstations. Cleaning and removing these spyware infections cost significant time and money that can be better spent on improving IT systems. Barring more draconian measures to restrict the use of web surfing and downloading files and other media, we strongly recommend the following safe surfing practices.

Make sure the web address fits the web site.  The web site address, (or "URL") should reasonably match the web site.  For example, if you on the web site of software maker Adobe, its web site address should be "http://www.adobe.com", or "https://support.adobe.com."  Web sites that claim to be Adobe's but have addresses like "http://adobe.0012441tojay.net" are likely phishing sites or web sites designed to infect your system with malware. You can also find out information about the owner of the web site address by performing a WHOIS ("who is") search.

Know your web address. Misstyping the web address for a well-known web site or organization can lead to web sites expressly built to capture misspellings. Many of these mimic a directory of links that you may find on the site you intended to visit, but are really advertising or meant to infect your machine with malware. Also, be sure you have the domain extension correct -- entering ".net" instead of ".com" may land you on a malicious web site.   

Do not click on any pop-up windows, especially one proclaiming that you may have a virus, spyware, or other malware infection.  In fact, the intention of that pop-up is to infect your machine, not inoculate it.

Did not click on any banners, pop-up windows or web pages saying you have won a prize. Almost always it is a rouse to infect your computer with spyware or adware. At the very least, it is an attempt to get personal information for marketing or more nefarious purposes. In fact, be wary of clicking on most banner ads. You can almost always find the site running the banner advertisement on your own.

Avoid downloading software and applications from the web.  The Internet has made delivery of applications and media much easier, but stick with trusted companies, sites, and organizations. There are a host of blogs, discussion forums, and consumer web sites where people report their experiences with web sites and online software vendors to check their reputation.

When in doubt, search Google. Usually searching on the web site name or organization on Google will provide a wealth of links to let you assess the reputation of a web site and those behind it.

Just like any scam, the common sense adage that "if it seems to good to be true, than it probably is." The Web is full of great discount web sites like Woot.com, but if the price of some consumer item or software is outrageously low, likely the site is trying to scam you for your money, likely injecting some spyware or adware at the same time.  If you are bargain shopping, stick with Ebay or Craigslist.

Following these guidelines should reduce the amount of spyware and other malware. Many of the same rules apply to unsolicited emails.  Don't click on links in spam e-mails or from senders you don't know, no matter what the promises to your financial prospects or "prowess."
