The truth is by default when your computer arrives it has many services and unneeded programs that can be turned off or deleted without harm.

If you have a lot of big files there, that means trouble. Apparently folders are not loaded. Shortcuts apparently are loaded, but it stops there.
The applications the shortcuts point to are not loaded. Maybe downloaded exe files are though. You'll be much happier.

If you don't have an up to date antivirus program, and don't want to pay for a new one, there are several high quality free ones available to the private consumer. Also look into a new different kind of antivirus program ThreatFire which you can use to supplement your other antivirus.
ThreatFire doesn't look for the fingerprints or DNA of known viruses. Instead it looks for suspicious behavior like key logging. Also try the no longer free WinHki Anti-Virus, which acts as a supplement to normal Anti- virus program like above. WinHki calculates the checksums a mathematical calculation extremely difficult to fool of your files on initialization.
After that, whenever a virus changes a file it will be flagged by WinHki because the checksum will change. Also check to make sure it updates at night. Perhaps it is updating during the day too instead of the default 3 AM. That could be a real slower in performance. Perhaps most people these days are buying full computer suites to use with their computers, which should include antispyware programs, but it doesn't hurt to independently run stand alone anti-spyware programs.
Note it's also a good idea to use the free spyware prevention tool, Spyware Blaster. Stop Unneeded Startup Programs New installation of software often adds unneeded startup entries in any of several different hidden locations.
