If you notice your computer randomly opening or closing programs, an increase of pop-ups, slow performance, or god forbid, the dreaded BSD (blue screen of death), you probably have a computer virus. While this kind of thing is best left in the hands of a Cleveland virus removal specialist, here is a definitive list of things you should do when you have contracted a virus.
1. Do disconnect from the network
The first step you need to take is to disconnect from your wired or wireless network. This will help prevent he virus from spreading to other network-connected devices. You will still need internet access, but will want to be removed from the network. To do this turn off the wireless network locator function and disable all file and printer sharing.
2. Do lock traffic with your firewall
Hopefully by now you’ve taken steps to install a strong firewall program to filter or stop all internet traffic completely. When you lock down the firewall you prevent the virus from spreading or accessing the internet. If you don’t have a firewall you can still disable your network connections or simply disconnect the Ethernet cable. The disadvantage here is that if you don’t have the latest updates for your anti-virus program, you’ll need to download and install them before locking the system completely.
3. Do update your OS
A lot of times defeating a virus or malware could be as simple as updating your operating system. Windows and Mac both issue regular updates for their operating systems that will block any security gaps and prevent the virus from spreading.
4. Do update and run your Anti-Virus software
Make sure you anti-virus software is fully updated and run a full system scan to find and eradicate the malicious program. This is really the only way to confirm the presence of a virus, and the easiest form of virus removal. While Mac is well-known for not being exposed to viruses, there have been reports of malware attacks on Apple’s product line, so it’s still very important to have a strong anti-virus package on your Mac.
5. Do reinstall your OS
While typically this would be a last resort, there is one final way to rescue your PC. Hopefully you’ve been backing up your files regularly so you won’t lose any files in the process. If not it may be collateral damage, but at least you won’t have to buy a new computer. Perform a disk wipe and then reinstall your operating system with the installation disks you should have from when you bought the computer.
So now that we’ve covered some “DO’s” for what to do when you get a virus, in the next post, I’ll cover some definitive “DON’T’S.”
