If One Piece Of Malware Slips By Your Computer Is Compromised
RELATED:How to Remove Viruses and Malware on Your Windows PC
The key to securing your computer is ensuring it doesnt get infected in the first place. Thats why people run antivirus applications that can check programs before they run, ideally preventing a piece of malware from running even once. If malicious software makes it through this protection, it has free rein over your system until its discovered and removed.
This is a problem for many different reasons. The malware can take this chance to burrow deeper into your system, hiding itself from being discovered by installing a rootkit that starts up during the boot process. It can infect various system files. It can use its access to transmit your personal data, credit card numbers, and passwords over the Internet.
Worse yet, malware can function as a Trojan horse, opening the floodgates to additional malware that it will download and install from the Internet. If you find your computer is actually infected by a piece of malware, you dont know if thats the only piece of malware thats infected your computer.
How To Protect Your Computer From Viruses
Here are some key ways that you can protect your computer from viruses:
- Use anti-virus software or a complete internet security solution, like Kaspersky Total Security. For your Android mobile, consider Kaspersky Internet Security for Android.
- Research apps and software by reading user reviews.
- Read developer descriptions before you download apps and software.
- Only download apps and software from trusted sites.
- Check how many downloads apps and software have. The more, the better.
- Check what permissions apps and software ask for. Are these reasonable?
- Never click on unverified links in spam emails, messages or unfamiliar websites.
- Do not open attachments in spam emails.
- Keep software, apps and your operating system updated.
- Use a secure VPN connection for public Wi-Fi, like Kaspersky Secure Connection.
- Never insert unknown USB sticks or disks into your computer.
