Virtual Memory Low-Is it worth buying a speed up?

Hi,
I've had a message saying my Virtual Memory is low and had no idea what this was so googled it. Most of the sites that came up had a 'Speed up your PC' to download so I did. It scanned my system and said I had over 400 problems but to fix them I had to buy it! Is it worth me paying for this or not?

No. Don't do it. It is a registry cleaner and there are no problems with your PC. The program defines them as "problems" so they can then "fix" the non-existent problems, damaging your system in the process. There is no program in existence that can reliably scan a Windows system and tell you what problems it has. If there were, this site would not be needed and most repair shops might as well close, too. They would only have business replacing failed hardware.

As far as virtual memory goes, it may be a false message due to malware, or you may need to increase the size of your page file.
