Overclocking is never a "safe" activity. To overclock, one must be willing to accept the hazards of such including shorter life and occasional burnout of the processor if you exceed the max limits it was manufactured to operate under.
Some of the "hobbyist" or "game" priority motherboards already have some degree of overclocking processes built in so they do so automatically.
I would research thoroughly and become expert before I traveled that path. You could do irreparable damage to your processor and motherboard.
By the way - I don't believe ram managers do anything worthwhile for an XP machine. The op system is more capable of regulating ram than third party code is.
It looks like you could use some web based scans (requires IE not Firefox)Web based online Antivirus and anti-malware scans:
(these can be run regardless of whatever else you are using. You must use Internet Explorer to run these.)
Panda Activescan (IE only)http://www.pandasoftware.com/activescan/co...n_principal.htm
Trend Micro antivirus and malware scan:http://housecall-beta.trendmicro.com/en/st...orp.asp?id=scan
Etrust Anti-virus web scannerhttp://www3.ca.com/securityadvisor/virusinfo/scan.aspx
Kaspersky Anti-Virus Web Scannerhttp://www.kaspersky.com/service?chapter=161739400#betatest
and - some additional anti-malware programs:Anti-malware freeware
(You can run as many of these as you wish. Unlike resident AV programs like Norton, McAfee, etc generally exhibit no conflict between these and you should always run several)
Microsoft Antispyware Beta: http://www.microsoft.com/athome/security/s...re/default.mspx

This one for coolwebsearch and some additional nasties:
CWShredder from InterMute
CW Shredder removes some variants of spyware known as the Coolwebsearch Trojan. The Trojan takes advantage of a flaw in a key component of Windows -- Microsoft's version of the Java Virtual Machine -- to install itself via popups often found on porn and illegal software (a.k.a. "warez") sites. Run CWShredder after installing, and have it look for updates. Then click the "Fix" button, and the program will both scan and fix any problems it finds. If your system does not have this kind of spyware, it will give you the good news.
