Dealing with a Virus

How to Tell If Your Computer Has A Virus

Your computer might be infected with a virus or other kinds of malware if it exhibits unusual symptoms and behaviors.

Computer Virus & Malware Symptoms

Below are common symptoms that may indicate your computer is infected with a virus:

  • The computer runs more slowly than normal or takes a long time to start up. 
  • There are unfamiliar programs or processes running in the Task Manager.
  • Your antivirus program is disabled, and you cannot run it.
  • Applications on your computer don't work correctly.

If You Suspect You Have a Virus

If you suspect your computer has been infected with a virus, do the following:

  • Update your virus definitions immediately. Manually run LiveUpdate to get the latest virus definition files from the vendor's web server.
  • Run a full system scan. If a full system scan reports that there are no viruses, your system probably isn't infected. However, if you're still unsure check with your LSP. If you are unable to run a system scan, then you probably have some type of malware on your computer.
  • Disconnect from the network.
  • Notify your LSP immediately, and follow their instructions. For information on where to go for computing support services and how to contact your LSP, check the Support Look-up Table. You can also contact ISC Client Care at 215-898-1000 for a referral.
  • Make a list of the software used on your machine that may need to be reinstalled, then gather the CDs and/or serial keys. Your LSP may need these items to reinstall software. (Even if your LSP doesn't need this information, it's a good practice to keep all this information in one location for your own record keeping purposes.)
  • If your computer will be unavailable because the hard drive needs to be wiped or reformatted, you may want to discuss the following topics with your LSP:
    • Whether you have been backing up your files on a regular basis (Viruses are not the only reason to back up data -- hard disk failures and power surges are just two ways that you can lose important data and work. You should be backing up your data on a scheduled basis.)
    • If you have lost information that will need to be recovered.
    • If you have software that will need to be reinstalled on your machine from the original disks or serial keys.
    • How configuration settings for restored software programs will be handled.
    • If the LSP needs software CDs and serials keys (see "Gather Your Software and Serial Keys" above).
    • If loaned a temporary machine, what, if any software on the infected machine will need to be uninstalled so that a copy can be installed on your loaner. Some companies have restrictions on the number of copies that can be run on different machines.
