Why is spotlight search intermittent when searching reminders? It works about 1/4 of the time.

Question

When I use spotlight to search reminders (or even if I use the reminders search function, I can see the reminder item but when I hit 'search' I cannot open the reminder - it just disappears!

Answer 1

This is indeed caused by a virus - and that I'm 99.99% sure (beware of the 0.01% though) - I've searched some forums around and it really seems to be malware.
Edit: Be sure to update your current paid antivirus and to perform an on-demand scan before buying another.
You're gonna need other security tools to test this, since your infection is probably TDSS or others. These kinds of malware tend to install more malware, that installs more malware, and so on.
Your best bet here is a paid antivirus, but there are more antivirus in this world that you haven't tried, such as,

[http://www.spywareterminator.com] ,
[http://www.microsoft.com/security/malwareremove/default.aspx]
If none of these work, I'd highly recommend a paid antivirus (this is a potential rootkit, not exactly the easiest thing to detect)
Good antivirus to choose from:
-TrustPort*
-GDATA*
-Kaspersky
-AVIRA
-F-Secure -ESET
-BitDefender (the one you own) -eScan
Antiviruses marked with * are partially based on BitDefender, and it might be best to look into others.
(in order of my personal recommendation in terms of detection-it might not be worth anything and it doesnt account for speed of scanning)
There are some free tools that have been "claimed" to solve this issue.
BEWARE: THESE TOOLS ARE A MERE PART OF RESEARCH AND ARE NOT ENDORSED BY MOZILLA. USE AT YOUR OWN RISK.
