How often you use anti-malware applications to scan your hard drive really depends, I would suggest, on your surfing and downloading habits, and the frequency these find malicious files. If, for example, you never go on-line without your firewall and Antivirus real time protection enabled, and if you do not visit potentially dangerous sites or download files without careful research, and if you use an alternative browser to IE, then I suggest the following that a weekly schedule should include a thorough scan by your Antivirus first, and by at least two of your Anti-spyware applications (the order of the latter is unimportant), with appropriate action taken after each scan.
I would avoid the use of registry cleaners entirely, as the benefits of their use are minimal, and the danger to your computer's ability to run are great.

John.....As a 'Newbie" I understood your suggestions up to your last sentence where you mentioned registry cleaners. By that, do you mean that CCleaner and PC on Point are registry cleaners and should be avoided?
