Is your Computer is running slowly and not functioning properly? One possibility of the slowdown is a virus infection.
A type of virus, called a parasitic virus, spreads by piggybacking onto computer programs. When a user launches the infected program, the virus will run as well. Then, the virus can replicate, install itself into the memory, and release its payload.
The payload is a part of the virus that performs the malicious operation. Examples include:
• Opening a back door for remote attackers to access an infected computer, and then downloading and executing more malicious files.
• Formatting the hard disk of the infected computer and deleting files with no possibility for recovery.
• Spreading the virus on the computer and infecting the drives, including removable and shared drives.
• Disabling the computer operations and showing a “blue screen of death.”
• Running key logging programs to collect system and network information, record user login information, and steal sensitive information.
• Disabling or deleting files associated with security related software, including anti-virus and firewall programs.
• Damaging operating system files by modifying system level files and the Windows registry.
How do parasitic viruses infect devices?
• Users clicked and/or downloaded infected email attachments.
• Users installed malicious software masked as virus removal tools.
• Users visited and downloaded materials from shady websites, such as media pirating and porn websites.
• Users inserted infected external media into their device, such as a thumb drive, external hard drive, DVD, and memory card.
• Users downloaded infected documents circulating on peer-to-peer file sharing networks and torrent sites.
• Users installed programs designed to crack licensed software and use it for free, such as Microsoft Office.
Symptoms of a parasitic virus:
• Sluggish computer performance.
• Your internet browser’s default home page and new tab page changed unexpectedly.
• You get bombarded with numerous pop up messages.
• You get redirected to malicious web pages
• Weird tool bars appear at the top of your web browser.
• Your web browser freezes and/or becomes unresponsive.
• Access to security related websites is blocked
• Strange shortcut icons appear on your computer desktop.
• Files and folders inexplicably disappear
• Your computer displays the “blue screen of death.”
• You experience problems with starting legitimate software.
Prevention is the best method of fighting against viruses:
• Scan the system with up-to-date anti-virus software on a weekly basis.
• Run backups of device and shared drives regularly.
• Be careful with inserting other people’s USB media. Make sure your anti-virus software scans the drive upon insertion.
• Don’t visit questionable websites, such as media piracy, torrent, and porn sites.
• Don’t open strange email attachments, especially from recipients you don’t know.
If you suspect your computer is already infected with a virus:
• Contact your IT support provider. If you need assistance from SwiftTech Solutions, call 877-794-3811 or email [email protected]
• Make sure other factors aren’t the cause of any device slowdowns, such as running out of memory and hard drive space.
• Disconnect the computer from the internet until further instruction by your IT provider. This can prevent the virus from spreading and stealing private data further.
• Boot the computer in safe mode and scan your computer with two antivirus programs, such as Trend Micro and Malwarebytes. After the scans, use CCleaner to clean the Windows registry. Your IT provider can assist you with this task.
• Don’t visit any personal accounts that require a password, such as banking or social media. If you did this already, go to a different device and change your password immediately.
• Your IT provider can attempt to use the computer’s restore function to return the computer back to a point in time before the virus infection. However, some viruses disable this function.
• The last resort option is to perform a complete system wipe of your devices by reformatting your hard drive and reinstalling the operating system. Make sure to backup virus free files before performing this operation.
