Thinking that only antivirus slows down the system is not entirely correct.
1. Data Mines/Advert, does it a lot more.
2. MSN messenger slows down your computer dramatically.
3. Unnecessarily launched programs at startup - too.
4. Too many programs at Quick Launch Bar - of course.
Anti Virus programs don't slow down the computer. If you have a huge HD to scan, you can always leave the scan during the time you are not at the computer. It's not dangerous to have the computer on because it "eats" very little electricity and has qute good cooling system.
Uninstall MSN for fun to see the difference.
To uninstall MSN with one click:
1.Start - Run - [the following command below, copy and paste in the command window]
RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove
2. You'll be prompted to uninstall MSN.
