Virus Web FAQ -- Campus Computers
- How do I make sure my computer is updated or "patched"?
- Campus computers running Windows should already be updating automatically. Windows updates are generally released to the campus on Thursday nights. Please make sure you leave your computer powered on overnight on Thursdays to ensure you get these updates when they are released. Non-Windows computers are not updated by an automatic process. If you have questions about updates for your Windows or non-Windows computers, please contact your department's Technical Support.
- How do I know if my anti-virus software is up to date?
- Campus computers running McAfee anti-virus should already be updating automatically. If you have questions about your anti-virus software, please contact your department's Technical Support.
- How do I know if my computer is infected?
- Anti-virus software is often unable to detect viruses when they are first created. However, Information Security constantly monitors network traffic for early evidence of infection. Information Security or your department's Technical Support will contact you If there is reason to believe that your computer has been infected.

Virus Web FAQ -- Home/Personal Computers
- If your home/personal computer is infected
- If you think your personal computer has been infected with a Trojan or virus, or you have been told by the UTD Helpdesk that your computer is infected, please follow these steps:
- Contact the UTD Helpdesk. They can help you diagnose and fix many Trojan and virus infections. The Helpdesk CANNOT reformat your hard drive.
- Clean the Trojan or virus from your machine. If McAfee is unable to detect or clean the Trojan or virus and you have been told your computer is infected, these instructions may help you clean the Trojan.
- Reformat your computer if necessary. If your computer is infected with a Trojan or virus that requires a hard drive reformat, the UTD Tech Store can help you for a reasonable fee. Additionally, there are some Trojans that also require you to clean your Master Boot Record (MBR). If your computer is infected with one of these Trojans (TDSS/TDL/Aleuron rootkit, etc). make sure the MBR is also cleaned when the hard drive is reformatted as these Trojans can survive a hard drive reformatting if the MBR is not cleaned.
- Once your computer is cleaned, contact the UTD Helpdesk so they can confirm the Trojan or virus has been removed. They will then email the Information Security Office to have your account and access reinstated.
- How do I make sure my home/personal computer is updated or "patched"?
- 1. You can update your home computers running Windows using Windows Update
2. You can update your home computers running Apple Macintosh through Apple.
- How do I know if my anti-virus software is up to date?
- This answer depends upon the brand of anti-virus software you are using. Generally, you can schedule anti-virus software to update automatically on a daily basis for as long as your update subscription lasts. In many cases, the updates are scheduled automatically. See your software vendor's FAQ for questions.
Alternatively, UT Dallas has a free home version of McAfee anti-virus software available for download for UT Dallas faculty, staff, and student use at home.

- How do I know if my home/personal computer is infected?
- Your anti-virus software may alert you if it finds a virus that it can't clean. However, if the virus is one that your anti-virus software can't detect, it can be difficult to tell if your computer is infected. If your computer suddenly begins acting strangely, it might be infected. You should contact the appropriate vendor or possibly the store where you purchased it if you suspect a problem and are unsure of how to take care of it.
The following are also symptoms of a potential spyware or virus infection on your computer:
- Your computer starts running more slowly than usual
- Pornographic sites pop up unexpectedly when you surf the Web
- New sites are unexpectedly added to your Favorites list
- New toolbars are unexpectedly added to your Web browser
- Your home page is changed unexpectedly
- Pop up advertisements appear even when you are not connected to the Internet
However, there are some simple rules that you can follow that will help keep you safe on any computer.
- Keep your computer patched at all times. This includes not only the operating system but all applications that you run, including your Office Products -- MACS and UNIX systems, too. We are now seeing successful attacks against Adobe Reader, Adobe Flash and Shockwave, Windows Media Player, RealPlayer, Java and numerous other "third-party" applications.
- Be extremely cautious about downloading. Attackers have managed to insert malicious software into perfectly legitimate websites such as CNN, Fox News, Facebook and YouTube. When in doubt, don't click on the link!
- Don't ever click on a pop-up!
- Keep your antivirus software up to date. Update daily. Once a week is not enough.
- Do not ever respond to email asking you for your password. If you have the slightest hesitation about an email request, don't respond. If the email comes from your bank (supposedly), call them - or go to their website directly. Whatever you do, do not respond to the email.
- FireFox Mozilla can be used instead of Internet Explorer, where applications allow its use. Be aware that some sites will not function correctly with FireFox.
- Don't store usernames and passwords on your computer or in your browser. Clear your browser cache after you visit sites that require login credentials. If you have questions about this, visit http://www.wikihow.com/Clear-Your-Browser's-Cache
