Written by: Kevin GardnerA virus, or other malware, on your computer can be devastating. When hackers infiltrate your network, they can gain access to (and steal) sensitive business and customer information. Not only is your business compromised, but so are your customers.Even with excellent security measures, it’s still possible for malware to make its way into your network. Acting quickly is vital for protecting your computers, and the information stored within them. If your network has been infected, here’s what you can do.
Viruses and malware can get into your networkand on your computers in various ways – a seemingly legitimate email with a clickable link or downloadable file, a malicious website that has worked its way into search engine results, a popup ad with a warning. Perhaps a hacker has infiltrated your network and placed the virus there. No matter how it gets into your system, a virus is bad news.Viruses affect your network and computers differently depending upon the type. Some destroy your files and shut your computers down. Others act more subtly. You might not even know they’re there, at least not right away. Some signs of a virus include:
If your antivirus software doesn’t catch and remove the malicious code, you will need to act quickly to get rid of the infection from your network.
If you find out that there’s a virus in your network, disconnect from the internet immediately. This will help to prevent additional infections from an outside source. You should also take down your local network and disable file and printer sharing to stop the virus from spreading between machines.
Make sure that all of your computers have the latest updates for antivirus software and scan your computers. Then, disinfect them. If the software can’t get rid of the code, you may need to reinstall your operating system, which will erase all files and software from the system.
Once the computers have been cleaned, restart them and scan them again. If the malicious code finds its way into your system restore files, you will need to temporarily disable system restore before restarting. After the restart, the infected files should no longer be there.
After eliminating a virus from your network, you need to take steps to ensure that another one doesn’t get in.
