LSA is a legitimate part of Windows and includes lsass.exe, LSA Shell, LSASS, (Local Security Authority System Service). The Local Security Authority or LSA is a key component of the logon process in WinXP (as well as NT & Win2000). The LSA is responsible for validating users for both local and remote logons. The LSA also maintains the local security policy. During the local (interactive) logon to a machine, a person enters their name and password to the logon dialog. This information is passed to the LSA, which then calls the appropriate authentication package. The password is sent in a nonreversible secret key format using a one-way hash function. The LSA then queries the SAM database for the user's account information. If the key provided matches the one in the SAM, the SAM returns the user's SID and the SIDs of any groups the user belongs to. The LSA then uses these SIDs to generate the security access token.
Answer---

The link for the word "THIS" is nested within the outer link. Nested links are not allowed by the W3C standards for HTML. Most browsers will either ignore the inner link or move it out of the outer link. However, nested links are allowed and sometimes encouraged in some programing languages.
Internet protection can save you from virures, spam and other malware from getting on your computer. These viruses can steal your id, use your computer's resources and send you numerous emails or worse, shut down your computer.

What are the limitations of antivirus software?
- Anti-virus software, especially free programs, can be limited because they can protect computers for certain virus variants only but will not protect computers for the more sophisticated ones.
- Anti-virus software depends on the signature files that contain the latest virus information, and the new viruses are not included in the signature files which limits the capability of anti-virus software to catch new viruses.
- Most anti-virus software cannot detect and clean zero-day exploits which means the viruses that spread and infect many computers in zero number of days, even before security experts can identify them as malicious.
These are a few limitations of an Antivirus Software.

How do you automatically defragment your computer every week?
If you want to run the windows dferagger, then set the scheduled task for whatever time on any particular day of the week (Actually its scheduled to do so by default in Vista and Win7). Its not the most reliable especially if your PC is switched off and when it runs the next time, it sometimes doesnt defrag completely. Alternative automatic options include commercial defrag programs that can be set to run in the background in real time and need no scheduling. More efficient and time as well as effort saving.

Your computer has been infected with malicious software. Since you do not seem to be technically inclined, try these
a) grab a geek. This could be a technically inclined friend, or a guy from a paid service.
b) back up your data while you still can. I cannot stress this enough. Copy all of your important files (pictures, documents, music, etc...) onto another hard drive (internal, external, UMS-enabled iPod) or flash drive. This way, if worse comes to worse, you will always be able to wipe your computer, reinstall everything, and still have your data.
Though there are many ways that you could have been infected, the majority of such infections comes from torrenting files (uTorrent, Limewire sound familiar?) and visiting objectionable websites *ahem*
