Will System Restore Get Rid of a Virus

The debate of the Century: Does System Restore Remove a Virus | a Lost Cause

There used to be a time when you could just delete a virus and go on with your day. But as defenses like anti-malware and anti-virus software developed, so did the virus. 

The virus developers are getting creative and using evolving and shadowing viruses that can replicate regular files. Hence it gets hard for your antivirus to find them. 

While a system restore can be an option to revert the virus attack, you need to know a few things before doing it. 

  • Where Did the Virus Attack?

Most viruses go for the system files first, and then other files. Doing a system restore will remove the virus and go back to your past settings. Which sounds great. 

  • The Time of the Attack

Viruses, like a disease, lurk around and change things to their benefit before exposing themselves. They are more camouflaged these days. 

So when you notice your system is infected, it’s already too late. 

Will System Restore Remove the Virus?

In summary and effectiveness, system restoration won’t do you any good. Especially with today’s malware or viruses, they spread throughout the system before you can take action. 

And restoring your computer won’t do any good. Because the restoring process also gets infected in the beginning. Which will do you more harm than good. 

What Should I Do After a Virus Attack?

The best thing to do after a virus attack is to take it offline. Disconnect the internet service and start your pc in safe mode. 

Check for anything valuable in the documents that can be backed up. And then install an antivirus and anti-malware software. Do a thorough scan without going into any of your hard drives. Because it might let the virus in. 

After the scan is done, disinfect and delete the files that are infected. 

And install the operating system from scratch. With this, even if there are any malware or virus left in the system, they will stop spreading. 

When you start your new OS, again do a deep scan and delete if any of those malware and viruses are left.
