4. Do not blindly click on a link without first hovering over it to see its destination, especially if the URL is short.

1. Update your computer regularly

All computer operating systems receive regular upgrades that improve functions while also adding security patches that close security gaps before hackers do in information security.

While we know that updates can be a headache, getting a virus on your computer network security is much more disruptive.

In addition to updating software like Adobe and Java, we advise our clients to turn on automatic updates for their PCs. Make sure you are connected to a secure network and not, for example, at a coffee shop before allowing any updates.

2. Internet Explorer should not be used

Although it can be difficult, the time we are in now is exhilarating. There are so many different browsers available. Any of that alternatives-Chrome, Firefox, or Opera-are safer than Internet Explorer.

3. Make a Computer Backup

Some computer infections keep coming back and are impossible to remove from a computer, as in our cautionary tale from above. You might need to remove some of your own data if this occurs.

Having multiple antivirus programs installed on your network is often not necessary and a poor idea. Every day, new computer viruses and malware are developed and found.

Your anti-virus software program’s effectiveness depends on how well it can keep abreast of computer viruses that could endanger you.

For this reason, make sure your antivirus program updates automatically and at a reasonable time – not 3 am on Wednesday nights because it’s unlikely that your computer’s malicious website will be turned on at that time, and not at 2 pm because you’re certain to have numerous meetings – and not when it’s likely that you’ll be using it.

This will make updating easier and protect you from the most advanced viruses available.

5. Stay away from dubious websites

Currently, there are more than a trillion web pages available. We spend a lot of time studying, buying, communicating, and perusing the internet, all of which require accessing many websites.

6. Check Email Attachments Frequently

Email is one of the earliest methods of infection and is responsible for computer Norton antivirus viruses’ early internet-era notoriety. Some people secretly distribute infections to their acquaintances without even realizing it.

At Altitude Integrations, we’ve seen plenty of instances where our clients’ email accounts have been compromised. Once that account had been compromised, the attackers would utilize it to distribute malicious information to everyone on the address book list in antivirus protection.

Check Email Attachments Frequently

The best way to ensure your safety before opening an email attachment or clicking a link is to run it via an anti-virus program. You should also have some email virus protection through your mail provider or email service.

For instance, attachments in Gmail are automatically screened for malware. The email will be denied and you will be informed if there is a virus.

7. Implement a malware scanner

Although anti-virus is crucial and you should invest in a reliable solution, there is still a chance that the virus will get through and download to your computer.

It frequently lurks in your network while you are blind to it. A weekly malware-in hard drive check should be performed to ensure that infections don’t have a chance to spread farther across your network and to lessen the damage.

Many of these tools can be used with backups to ensure no dangerous files are backed up alongside your other files. They are frequently simple, inexpensive, and occasionally even free.
