Methods that guarantee a computer or network is safe from computer viruses, worms and trojan horses simply do not exist. Users can take several precautions, however to protect their home and work computers from these malicious infections.
Now before we get to these tips I am going to share a reality and it is that protecting your computer with free anti virus software is not enough, you get what you pay for and usually these free virus protection programs are actually worse than the viruses that you could get, this is why I much rather pay for a piece of software that will truly protect my computer because from my own experience, free antivirus software is not good at all, I have been using the paid version of Malwarebytes with great results.
Below are several tips that will help you keep your computer protected.
1. Never start a computer with a usb flash drive unless it is an uninfected recovery disk, specially if you do not know where the drive came from, it is easy to install malware from an infected drive and get computers on a network compromised.
2. Set the macro security in programs so you can enable and disable macros. Only enable macros if the document is from a trusted source and you are expecting it, this applies to email as well, if you receive a document from someone and they have macros enabled be careful.
3. Install an antivirus program on all of your computers. Obtain updates to the antivirus signature files on a regular basis, most malware applications will automatically download updates but not all of them have the best virus definitions, this is why I always recommend that you buy Malwarebytes and install it on all of your computers.
4. Check all downloaded programs for viruses, worms, or trojan horses. These malicious-logic programs often are placed in seemingly innocent programs, so they will affect a large number of users. Windows 10 has built in tools that protect your computer against malware, keep your operating system patched at all times.
5. Never open an e-mail attachment unless you are expecting it and it is from a trusted source. Scan for viruses in all e-mail attachments you intend to open. Turn off message preview. Always question any unsolicited email and be careful on taking any kind of action like clicking, downloading or filling out any forms.
6.Write-protect your recovery disk by sliding the write-protect tab into the write-protect position, specially when using external drives that could write directly to your computer hard drive.
7.If the antivirus program flags an e-mail attachment is infected, delete the attachment immediately and reboot your computer, run a full system scan after that.
8. Before using any usb drive, use the antivirus scan program to check the disk for infection. Incorporate this procedure even for shrink-wrapped software from major developers. Some commercial software has been infected and distributed to unsuspecting users this way, be cautious too when downloading free software from the internet.
9. Back up your files regularly. Scan the backup program before backing up disks and files to ensure the backup program is virus free, create multiple copies of your backed up files and store the in different hard drives.
