We all suffer from computer viruses day in day out, ever since the very first known computer virus, Elk Cloner hit Apple users way back in 1982 as a prank created by a 15-year-old high school student. But now it has become a serious threat to all of us and Paladion, the global security specialists recently shared 7 tips to protect our devices from viruses:

Tip #1 A virus usually has a signature, so using a trusted antivirus will help detect and stop it from infecting your systems.

A virus usually spreads via a:
1.a) USB
2.b) Drive by downloads
3.c) Email
4.d) Rerouting a Web

So, be watchful during these activities.

Tip #2: Disable Autorun on your system and ensure you scan your USB before use.  Some antiviruses have options to automate the process.

Tip #3: Use a secure browser and an updated browser.  Browser exploits are very common and an updated browser reduces the threat surface by a lot. As an additional security measure, using a No Script Plugin can disable scripts from all websites and you can white list trusted websites to run script.

Tip #4: Do not open email/links that seem suspicious or are not intended for you.

Tip #5: Most antiviruses have browser protection.  Just ensure that the feature is enabled.

Tip #6: Use a host firewall and ensure inbound connections are in block mode unless absolutely required.

Tip #7:  This is a PRO-TIP ensure all unnecessary services are turned off if not required.   Configuring your system to match the CIS Hardening Checklist for Windows is a good approach.
