Software have become an essential part of businesses, especially for the small 
and medium sized businesses (SMBs) and is not only playing an important role in 
increasing the productivity, but also increasing the profits of the business. But, 
SMB owners have to be alert and aware of the threats to the software that are 
installed in the computer.
Software threat can be a deliberate attack and in some cases it can be significant. 
While, sometimes an accidental and general attack by one or more malicious 
programs.
There are many threats to a computer software and we will discuss the most 
common threats like Virus, Trojans, Spyware, Worms and Logic bombs in this 
article.
Virus
Virus are malicious programs that enters or attacks other programs. They may be 
injected deliberately into your computer/software or entered accidentally into 
your software program through other installations.
Virus takes over the other programs and corrupts the data. Small businesses must 
be aware and careful about the Virus.
Trojans
Trojan is so named after “Trojan Horse” from the history of Troy. Trojans do not 
enter or take over other computer program like Virus, but gives backdoor access 
to the hackers.
Trojans are not self-replicating. They spread deliberately by hackers to control 
others operating system.
The effect of the Trojan may be many times greater than Virus as they delete 
critical data, hangs your computer and gives unauthorized access to hackers.
Unfortunately, Trojans cannot be identified by normal users. The only way to 
identify is when your computer slows down or hangs up.
Spyware
Spyware is a computer program that collects information about the computer or 
the user of that computer and passes it to other entities for various reasons. 
Usually they are used to track or steal the confidential information about your 
business from the computer. Spyware is similar to Trojan, it cannot be identified 
by the user.
Worms
Worms are considered one of the serious threats to SMBs, as they have multiple 
computers connected in a network. As the name suggests worms crawl from one 
computer to other through network or e-mails, or other connectivity.
They are self-replicating. They produce many replicas of themselves that again 
re-produce many more worms exploiting the operating systems of the computers.
Logic bombs
Logic bomb is also called as “slag code”. Logic bomb is a computer Virus or 
Trojan, but they do not act on their own. They need to be triggered to make them 
work (explode). Logic bomb when exploded corrupts, steals or deletes 
information from the system.
Logic bombs can be identified by false or unwanted messages being printed on 
the user’s screen when exploded.
So, SMB owners should be aware of these five common threats to software. We 
post the counterattack techniques and security measures to be taken to prevent 
these threats in our next article.
