How To Tell if Your Computer Has a Worm
Monitor speed and performance
If your computer has been running sluggishly, there is a chance it has a worm. Also, if some programs are crashing or running improperly, a worm could be the cause.
Be on the lookout for missing or new files
Worms can delete files on your computer and then replace them with something else. If you see new files or notice some that are missing, it may be because of a worm.
Keep an eye on your hard drive space
Because worms replicate, again and again, they often take up large amounts of hard drive space. If your free space is getting eaten up, it could be due to a worm.
Stay Protected Against Computer Worms
Invest in a strong internet security software solution
One of the best ways to get malware protection from computer viruses and worms is to use powerful security software. A strong antivirus product will be able to combat phishing, spyware, malware, Trojans, and other cyber threats.
Be extra cautious against phishing
Anytime you open an email you are not expecting, particularly from senders you do not know, check for suspicious attachments or links. They may contain worms or a command that automatically downloads a worm onto your computer.
Update your operating system
If your operating system is up-to-date with the most recent version, you are more likely to be protected from worms and other malware. Manufacturers are constantly on the lookout for vulnerabilities, and they often release patches that address them in operating system updates.
