False alarms
•
0 likes•233 views
A false alarm occurs when an anti-virus program mistakenly flags an innocent file as infected. This can be costly and cause productivity losses from user downtime and time spent trying to disinfect uninfected files. False alarms happen for reasons such as anti-virus programs making it difficult to analyze protected files, overzealous heuristic detection, and software errors. Common files and programs that tend to trigger false alarms include adware, browser toolbars, and anti-virus software itself. The best way to handle false alarms is to check if the file or program has a trusted security seal from other reputable anti-virus vendors.

False alarms
A false alarm occurs when an anti-virus program mistakenly flags an innocent file as infected. This can be costly as it wastes time and resources to investigate and disinfect the falsely detected files. False alarms happen for reasons such as anti-virus programs making files harder to analyze, over-detection of protected files, and errors in heuristic analysis. Common files that generate false alarms include software from companies like AVG, Kaspersky, and Eset as well as programs like Skype, Babylon, and Imesh. The best way to handle false alarms is to check if the anti-virus program giving the alarm has a trusted seal from a major anti-virus company.

A computer virus is a malicious program that attaches itself to other files and programs to spread without permission. It can slow down or crash an infected computer by using system resources. A Trojan horse also spreads maliciously but does not replicate, instead masquerading as a desirable program. A worm replicates like a virus but spreads through networks instead of attaching to files. Antivirus software with up-to-date definitions is the best protection, but it requires regular updates after subscriptions expire. Backing up important data files regularly and storing backups separately is also crucial, as hardware and files will inevitably fail or become corrupted.

While email filtering and security software help, they are not foolproof. The document argues that the only sure way to mitigate ransomware threats is through regular, versioned data backups that allow restoring files from before infection. Backups not only protect against ransomware but also other data loss causes, providing overall systems continuity for businesses.
What is malware
Simon Pell gave a presentation on malware threats facing small businesses. He defined different types of malware like viruses, trojans, worms, and rootkits. Viruses self-replicate and infect files, while trojans and worms do not self-replicate but can still damage files. Rootkits are used to hide other malware. Spyware/adware collects user information without consent. Cookies are small text files that store website preferences. Pell stressed the importance of using updated antivirus software, firewalls, and being cautious of downloads. Firewalls can control network access and applications without slowing performance. Unified threat management provides additional protections like blocking suspicious websites and spam.
AEPWP09292016
- Traditional endpoint protection has failed to prevent the increasing number of data breaches, with roughly five times more breaches occurring today than 10 years ago despite increased spending on cybersecurity.
- Existing approaches fall into the categories of "default allow", which allows unknown files and leads to compromise, or "default deny", which blocks productivity.
- Comodo's "true default deny" uses lightweight containers to run unknown files safely without risk of infection, while cloud-based analysis determines if files are good or bad very quickly, providing security without compromising usability.

Malware Protection
Malware protection use to be known simply as virus protection. We have learned that
viruses are one form of malicious software and that a broader term to describe the
multitude of threats and the protection mechanism is needed. This is why the term
Malware is broader categorization of the threat and also the protection. Malware is a
portmanteau of the terms Malicious Software. Different malware protection packages
can cover a range of threats including viruses, worms, Trojans, spyware, adware, rootkits
to name a few.
As malware has evolved so has malware protection. Malware protection packages (MPP)
have evolved to provide more comprehensive protection mechanisms; including
firewalls, Intrusion Detection/Protection Systems (IDS/IPS), remote and central
management of system clusters, heterogeneous system protection and management,
signature and heuristic scanning, sandboxing to name just a few features.
It is important to understand that no one Malware Protection Package will find all pieces
of malware. Each package has its strengths and weaknesses. It is a good idea to always
have some form of malware protection running on your system in real time. However,
should you become infected it is useful to have an alternative strategy making use of
other scanners that you can run manually.
Free or Paid for Scanners
There is an adage that “you get what you pay for”. Generally this is true, but over time I
have found that there are some excellent free malware scanners that for single user
systems do a nice job. Some major requirements I have for a malware scanner are: it is
easy to run; does not require a lot of user interaction, uses little system resources, does a
good job finding and removing threats and automatically updates its signature database.
The following is not an endorsement for paid versus free scanners. It represents my
experiences for what they are worth.
I use to have a paid for Norton subscription. I found that over time the system footprint
for Norton grew which meant Norton required more CPU and overall system resources
for its real-time scanning processes. I think Norton has got better based on recent
experience I have with Windows 8 however at the time I had several performance
problems related to Norton. This got me to switch to free AVG. I used AVG for a while
and had real good luck, until AVG’s advertising got obnoxious. I decided to remove
AVG and found that process very difficult. I finally succeeded and then moved to using
free Avast. I have been using Avast for several years having very good luck.
I then started testing various malware scanners on virtual machines. This got me familiar
with Microsoft Security Essentials. This is a free product offered by Microsoft that nicely
integrates with Windows Vista and Windows 7 systems. I like the simplicity of its
inte ...
Justifying IT Security: Managing Risk
The document discusses justifying IT security programs and managing risk. It argues that security should be viewed as risk management rather than trying to achieve complete freedom from risk. An effective security program identifies vulnerabilities that could lead to losses if exploited by threats, and implements cost-effective countermeasures to mitigate those vulnerabilities. This optimizes risk while justifying security spending based on specific risks and countermeasures.

Scott Brown tested 13 popular antivirus programs using 10 zero-day viruses and 2 exploits. NOD32 and Kaspersky detected the most viruses initially, while after 1 week NOD32, F-Secure, and Kaspersky detected the most with updated definitions. Based on the tests, NOD32 used the fewest system resources and had the best support, leading Brown to conclude it was the best option. Brown will require NOD32 on all computers connecting to his college network.

False alarms
- 2. What are false alarms? A false alarm is another way of saying ‘mistake’. As applied to the field of anti-virus programs, a false alarm occurs when the program mistakenly flags an innocent file as being infected. This may seem harmless enough, but false alarms can be a real nuisance. You waste productivity due to user down-time. You may take e-mail offline, as a security precaution, thus causing a backlog and more lost productivity You waste even more time and resources in futile attempts to disinfect ‘infected’ files. And if you load a backup, to replace ‘infected files, the backup appears to be infected too. In short, false alarms can be costly nuisances. The term is not confined just to the anti-virus world. It also applies, for example on Trojan protection and anti-malware. This too could be 2
- 3. very costly, for example an e-mail that marks as may be a business critical message. Why do false alarms appear? Difficult to say only one main reason of false alarms, but usual of them are following: - the one of the main purposes of protection systems – make it harder to analyze, reverse and crack the application. Malware (virus) makers are also very often use protection systems to protect viruses to make them difficult to analyze. So antivirus - Software vendors sometimes wrongly detect virus in any protected files, for example, if last days there were lot of protected viruses - Heuristic and generic analyzers of antivirus software may often fail, because these are robot, and automatic robot detections can’t give us 100% result 3

- 11. What you can do? There is no magic formula to solving the false alarm problem; Our best advice is to look for trusted seal or seal approval of some anti- virus software. Logically, Antivirus software will not risk their credibility by giving trusted seal or seal approval without a thorough examination. Here is a thumb rule for you: When a product is marked as trusted seal by one of the major AntiVirus software, and is caught by different AntiVirus software – then you know it's a false alarm.
