What to Do After a Virus Removal to Prevent Reinfection
You’ve gone through a painful computer malware or virus removal, and now you’re wondering, is it safe to use your computers again? Will you be protected? Or is that malicious threat still lurking somewhere in a flash drive or hidden file?
These are the questions that companies ask themselves after dealing with a virus threat that’s cost them a lot in both time and money. Ultimately, how can they keep it from happening again?
According to an article from the Graziadio Business Review of Pepperdine University, the average cost to a business of a data loss episode is on average $3,957, which includes the cost of lost productivity ($217), technical services ($340), and value of lost data ($3,400). A majority of companies estimate the average cost of computer network downtime to exceed $50,000 per hour.
So once a business goes through the nightmare of a virus and potential data loss, they never want to experience that setback again. That same article also notes that a computer outage lasting beyond 10 days is rarely fully recovered from financially.
The team at Powerkey IT Solutions has seen this all too often when called in for an emergency virus removal and security protection. They understand that every minute counts when your business is crippled by a virus attack.
Types of Virus Assaults
Not all computer viruses are the same, but they can all cause IT costs and productivity downtime for your business. Some can even steal or scramble your data and request a ransom of tens of thousands of dollars to restore it.
Here are some of the common types of viruses and malware that can infect one of your staff computers with just one wrong click on a file or website:
- Adware – automatically delivers pop-up ads on websites
- Bot – can cause a computer to be taken over by a third party
- Bug – can cause freezing or crashing of computer systems or security breaches
- Ransomware – scrambles data or locks system, holding it hostage for a ransom
- Rootkit – used to remotely control a computer and steal files or for DoS attacks
- Spyware – spies on and can record user activity without their knowledge
- Trojan Horse – pretends to be a normal file to deliver a virus that can cause harm
- Virus – designed to copy itself and spread over a computer network
- Worm – they exploit vulnerabilities in operating systems and software, can also self-replicate and spread
Steps to Take After Virus Removal to Avoid Reinfection
There are some steps that you’ll want to take after a virus had been removed from your system to prevent reinfection. There’s nothing worse than finally getting your computer back, just to have it start freezing up once more and have to go through the whole painful process again.
Change All Passwords
Viruses can often be used to steal user and administrative passwords. Change all the passwords on your computer and network server, including any for unused user accounts to help prevent reinfection.
Install a Firewall
A firewall acts as a gatekeeper to your computer network and can help keep out viruses and malicious threats. You will want to have an experienced network IT support provider install this, as sometimes it can block programs that your team normally uses in day-to-day business unless set up correctly.
Clean Memory Cards
Something that can often go overlooked is the possibility of an infected memory card that has been connected to the computer and now carries that virus and can reinfect the system as soon as it’s connected.
Memory cards can be located in:
- USB Flash Drives
- SD and SDHC Cards
- Camera and Camcorders
- Smart Phones
- Satellite Navigation Equipment
Delete Restore Points
You’ve deleted an important system file and need to use a restore point to get it back. But if you’ve had a virus on your system in the past, one of those restore points could cause it to be reinstalled on your system. It’s best to delete any old system restore points and then create a new one – post virus removal.
Use a Trustworthy Virus Scanning Software
To ensure your system isn’t infected again, you’ll want to regularly scan for any new threats. But make sure you use one of the most recommended and trustworthy virus protection tools. Otherwise you could be open to threats from a weak software or taken in by another virus masquerading as a virus scanner.
Hire a Experienced IT Support Service
Companies can save thousands to tens of thousands of dollars by simply hiring a company, like Powerkey IT Solutions, who can make sure your system is protected from virus threats in the future and provides continual monitoring.
The cost of hiring expert IT support is just a small fraction of what you’ll pay in lost productivity and data loss costs in the event of a virus. And because they do this type of work every day, they know just what to do to keep your system protected continually, saving your team tons of research hours trying to figure it out yourself.
