There is this very pesky issue that has been going on in the computer world that has caused problems for so many people lately...
Malware, though not a virus, it is similar to the bane of so many computers.
It basically gets into your computer and causes damage to system files and can potentially lead to even worse problems in the future.
There are ways to protect your computer however! There are a couple of ways to do it.
One such way is getting a tool online that assists the process and makes it easier for you to remove malware.
They perform a full scan on your computer system with the sole purpose of finding malware.
In some cases the program will ask you if you want to delete the file, though sometimes you might need to keep it to run other programs that are in use.
So again it really depends on how badly you want to use malware infected programs or not.
If you don't want to use malware infected programs that badly, and I hope you don't, you should set up an automatic scan to happen once a day.
By doing this and leaving your computer on, it will find most any new malware that tries to sneak in.
You don't have to leave your computer on all day, but at least leave it on when you know the schedule is almost near.
As long as you do this your computer should run fine with no problems!
