I've heard a lot of such wrong sayings about computers, usually from parents and cousins. I know those weren't really true, but I'm not quite sure of the reasons behind this. But now through research, I think some of these misconceptions will be proven wrong.
Here are some of the popular beliefs about our computers:
Leaving your computer on for a long time will worsen a computer
Leaving your computer on for a long time will worsen a computer
Having your computer turned on for a long time (or have it turn itself off in standby or hibernate) isn't actually a big issue. This is fine as long as your computer has good components that can withstand your daily use. Because rarely, "stiction" (a tendency wherein the system has a hard time spinning into activation) may occur possibly, but in older computers only.
Deleting your files erases them forever
Many people believe that if you data in a computer, there wouldn't be found any traces of such files. But actually, if you delete those files, there's a possibility to find old social security numbers, personal files, and other information on donated hard drives if the hard drive hasn't been completely reformatted and Windows reinstalled. So, according to my research, to get rid of information for good, zap it with a free eraser utility like Eraser.
Magnets murder data
This is considered true in the generation of floppy discs. Hard drives are also safe from magnets. CDs and DVDs are as well immune to magnets. Memory cards are not also affected, considering that they are not magnetic in themselves. But endpoint, extremely powerful magnets can erase a hard drive but I guess that would not be frequently present.
Restarting is bad for a computer
This really isn't bad in the first place. Because restarting is like refreshing all the computer's data, and doing this will prevent your files to get clog as you input more and more data. And this will cause slow processes. And usually, this is the most preferred initial step in fixing a computer.
Antivirus isn't necessary if a firewall is already present

Antivirus isn't necessary if a firewall is already present
Actually, antivirus and firewall are of different purposes. An antivirus, locates, isolates and gets rid of viruses from the system. But a firewall, protects the computer from the unauthorized users, may be through internet, to get in to your system. So an antivirus couldn't have a solution to such unauthorized users, and a firewall cannot do the work of antiviruses either.
