How to Test the Working of your Antivirus – EICAR Test
1. Open a notepad (New Text Document.TXT) and copy the
following code exactly onto it, and save the notepad.
EICAR Test code
X5O!P%@AP[4PZX54(P^)7CC)7}$EIC
AR-STANDARD-ANTIVIRUS-TEST-FILE!
$H+H*
2. Rename the file from New Text Document.TXT to myfile.com
3. Now run the antivirus scan on this myfile.com file.
If the antivirus is functioning properly on your computer, then it
should generate a warning and immediately delete the file upon
scanning. Otherwise you may have to re-install your antivirus.
NOTE: Most antivirus will pop-out a warning message in the Step-1 itself
You can also place the myfile.com file in a ZIP or RAR file and run a
scan on it so as to ensure whether your antivirus can detect the test
string in the compressed archive. Any antivirus when scanning this file
will respond exactly as it will do for a genuine virus/malicious code. This
test will cause no damage to your computer even though the antivirus
will flag it as a malicious script. Hence it is the safest method to test
the proper functioning of any antivirus.

Did You Know?
The first Internet worm was created by Robert T.Morris, Jr, and
attacked more than 6000 Internet hosts.
Privacy Attacks :-
Here attacker uses various automated tools which are freely
available on the internet. Some of them are as follows:
1) Trojan :- Trojan is a Remote Administration Tool (RAT) which
enable attacker to execute various software and hardware
instructions on the target system. Most trojans consist of two parts -
a) The Server Part :- It has to be installed on the the victim's computer.
b) The Client Part :- It is installed on attacker's system. This part
gives attacker complete control over target computer. Netbus, Girlfriend, sub7, Beast, Back Orifice are some of the popular trojans.
2) Keylogger :- Keyloggers are the tools which enable attacker to
record all the keystrokes made by victim and send it's logs secretly
to the attacker's e-mail address which is previously set by him.
Almost all the Trojans have keylogging function. Use of latest updated antirus-
firewall, detect the presence of trojan and remove it permanently.
3) Spyware :- Spyware utilities are the malicious programs that spy
on the activities of victim, and covertly pass on the recorded
information to the attacker without the victim's consent. Most
spyware utilities monitor and record the victim's internet-
surfing habits. Typically, a spyware tool is built into a host .exe file or utility. If a victim downloads and executes an infected .exe file, then the spyware becomes active on the victim's system. Spyware tools can be hidden both in .exe files an even ordinary cookie files. Most spyware tools are created and released on the internet with the aim of collecting useful information about a large number
of Internet users for marketing and advertising purposes. On many occasions, attacker also use spyware tools for corporate espionage and spying purposes.
4) Sniffer :- Sniffers were originally developed as a tool for debugging/troubleshooting network problems. The Ethernet based sniffer works
with network interface card (NIC) to capture interprete and save the
data packets sent across the network. Sniffer can turn out to be quite
dangerous. If an attacker manages to install a sniffer on your system or the router of your network, then all data including passwords, private messages,
company secrets, etc. get captured.
What is the difference between a 32-bit and 64-bit operating system?
There are two main things to keep in mind when choosing between
a 32-bit OS and a 64-bit OS: memory support and software compatibility. There
are others, of course, but those the two most important. Typically 32-bit operating systems can only support up to 4 gigabytes of memory, while a 64-bit OS can theoretically support upwards of billions of gigabytes. 64-bit
operating systems are limited by artificial software and
hardware ceilings, but the ceilings are still much higher
than a 32-bit OS. So the short answer for memory support is this:
if you want more than 4 gigs of memory, you’ll need a 64-bit OS. Software compatibility is the other thing to keep in mind, and the more important, in my
opinion. Some software that runs on a 32-bit OS will not run
on a 64-bit OS, especially older software. Most modern
software will run on both 32- bit and 64-bit, but checking
your software before you upgrade is the only way to know. A little Googling can usually answer that question for you. When making your choice,
the bottom line is this: if you must have more memory than 4
gigs, go with a 64-bit OS. If you don’t need that much,
sticking with a 32-bit OS at this point in the game is a decent
choice, if only to ensure that your old software will keep on keepin’ on
