Hi Frnds...

This virus is very very common now...
To know whether ur system is infected just type C:\heap41a in the address bar...
if there is a folder named heap41a, then ur system is infected...
(AVAST antivirus is the best solution for this worm...) symantec also works.

How to block a particular site from home/office

This may not be a good solution, but its the simplest one.

If you are using Windows XP., open a DOS command window, type:

notepad C:\WINDOWS\system32\drivers\etc\hosts

Lets say that you want to block hxxp://www.rediff.com

Add the following line to the file:

127.0.0.1 hxxp://www.rediff.com

Do change "hxxp to http".
File > Save. You are done!

Increase bandwidth by 20% in Windows XP

A nice little tweak for XP-Pro only. M*crosoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..)

Here's how to get it back:

Click Start-->Run-->type "gpedit.msc" without the "

This opens the group policy editor. Then go to

Local Computer Policy-->Computer Configuration-->Administrative Templates-->Network-->QOS Packet Scheduler-->Limit Reservable Bandwidth

Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the 'Explain' tab :

"By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default."

So the trick is to ENABLE reservable bandwidth, then set it to ZERO.

This will allow the system to reserve nothing, rather than the default 20%.

works on XP Pro, 2000 but not on other o/s not tested.
