- Never open an email attachment that you were not expecting, even if it came from someone you know.
- Never trust a website to install software if you are unsure what it is or does.

How do I clean an infection?
The most effective way to be sure that you have fully cleaned an infection is to back up your data and completely reinstall your system. This is the only way to be 100% sure that the malware has been removed.
There are, however, many different pieces of software that can scan for and clean malware infections. The first scan you should run is your updated anti-virus software. See Anti-Virus Software for information on recommended anti-virus packages.
We also suggest running other software to clean malware infections. Many of these are free to download, but are not license for commercial use. This means that they cannot be installed on computers owned by the college. We are providing this information only for informational purposes. If you think your college-owned computer is infected, you should call the Helpdesk at 865-HELP (865-4357).
While we are providing this information, we cannot help you with the "ins and outs" of each of these programs. Please consult their individual websites if you have questions about them.
