If you delete it from C:\WINDOWS\system32 it reappear in 5-6 seconds. It's safe like Windows...
  Tommy Tomorrow  
You only need it if you want Microsoft Firewall. If you have an additional firewall program, you are probably okay in disabling it. If you share any files or programs and resources (for example through a corporate or school network), you should not disable it.

It just a crap and nothing happens if you end it. Sometimes when my internet gets slow I simply end it and what a magic.My net speed increased.

Normally harmless as already explained by many here, but i notice every time my internet slows down terribly it is due to alg.exe opening. It is used by skype and msn messenger and utorrent too, which can also be used by backdoor hackers to send stuff from your pc. Its to do with data sharing
