Virus Protection


Millions of viruses are currently circulating the Internet via e-mails, malicious websites and instant messaging. New ones are being released every day and infecting unsuspecting users who open e-mails that they thought were from a friend or visiting a website that required them to install something that said it would protect them.

The InfoSec team recommends using one or more of the following to help ensure your computer is free of viruses and other malware:


Windows AV Products


Lightweight AV (can run alongside other AV products)


Mac Users : there are free virus scanners available as well

  • Avast for Mac : This can be downloaded here
  • ClamXAV : This can be downloaded here
  • Sophos AV For Mac : This can be downloaded here

Cleaners

Although the majority of viruses currently plague Microsoft operating systems, Macintosh and Linux users should be aware that there are viruses that do target their systems. Macintosh and Linux systems can also contain Windows viruses that may not directly affect but can be transmitted to unsuspecting Windows hosts through file transfers over FTP, HTTP, instant messaging and file shares. We recommend that antivirus be installed on all operating systems. For Linux users, a free antivirus software, ClamAV, can be downloaded from http://www.clamav.net/.


I’ve received a notice from you that I’m infected — what do I do?

You can start by installing one (or more!) of the Anti-Virus products above and running full scans to detect viruses, worms and other forms of malware currently residing on your computer.

If you are still experiencing problems or you continue to receive notices from us, you should take your computer to the Help Desk. They can be contacted at 392-HELP or helpdesk@ufl.edu

NOTE: that infections that go unresolved for more than a week may result in suspension of UF network privileges until the problem is resolved.

ALSO: Particularly dangerous infections may necessitate the immediate suspension of network priviliges to protect your computer or private information from further harm, or to protect other UF resources from attacks from your computer.
