single file scanning site

there are many file scanning sites out there, the best 2, in my opinion, are:
www.virustotal.com and virusscan.jotti.org

some facts:
www.virustotal.com

• up to 20MB per file
• do not need to scan the file if been scanned before (can call up previous scan report)
• 40 scan engines (don't think this matters that much as only a few engines matter)
• upload progress meter/indicator (this is handy)
• upload is quite quick

virusscan.jotti.org

• up to 10MB per file (re-verification needed)
  
• cannot call up previous scan report
• 20 scan engines
• no upload progress meter/indicator
• upload can stall sometimes and have no warning - this can be frustrating
  
• this site is created by a fellow south african :) this is a big plus
  

remember, if you download apps/games via P2P, scan it. DON'T BE LAZY! Most of the time it contains something undesirable
