I saw that link, but that's for version 7. &nbsp;I'm already on version 8. &nbsp;I continue to search for a solution. &nbsp; Thank you though!

We recently changed over from McAfee to Trend. &nbsp;Excel opens slowly on my computer; regardless of opening a file to open Excel, or simply opening the program.<br />
<br />
When I disable Trend, Excel opens at normal speed.<br />
<br />
I've tried adding an exception to the path of Excel, as well as XLS and XLSX file types. &nbsp;I've also added it to a trusted program. &nbsp;No luck. &nbsp;When I close Trend, Excel opens fine. &nbsp;Any suggestions?<br />
<br />
I think it may be an add-in, however, I am unable to determine the add-in path or extension to exclude.

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.
