The most common complaint is a slow computer. If computer programs run fine and things only slow down when using the Internet, then call your Internet Service Provider (ISP) and asked about getting a faster Internet connection.
If a computer runs slow when a web browser isn't open, when starting up or shutting down, or if just a few programs are open, then adding more memory (RAM) and adjusting the virtual memory setting will likely solve the problem. (Don't confuse memory with a computer's Hard Drive - an explanation is here.) However, if the computer is four to six years old, it may be time for a new one.
If infected with Malware (spyware, worms, scamware, viruses, pop-ups or adware) the computer may also slow down as a result of opening multiple windows or processes in the background. Usually one infection leads to another so it is good idea clean up the situation before it gets worse. Conficker continues to be the most prevalent Worm worldwide, yet is easily identified and removed. It is good to know what signs to look for in determining if a computer is infected; here is a brief list.
Unfortunately, 70% or more of the anti-malware programs advertised on the Internet and on TV/Cable do not work as advertised, or are malware themselves. Most will scan your computer, and tell you that it is infected - even if it isn't - and then request that you purchase their program to fix the problems (this is called scamware.) Stick with well known product names! Also, most Internet service providers offer antivirus and other protection while you are their customer. If you use this alone, you might be minimally protected. Additional software may be needed to keep your computer(s) clean and running their best.
