Dangerously Incomplete Malware Protection

Dangerously Incomplete Malware Protection

By Bob Rankin

Bob Rankin provides a close look at the functionality of current antivirus software technology and why some methods of protection are dangerously incomplete.–PC Pitstop

Antivirus software’s first job is to detect viruses and other types of malware before they do their damage. There are two ways to identify malware, and a number of variations on these basic strategies. Here’s a plain-English description of how antivirus software gets the job done…

Different Types of Antivirus Software

Have you ever wondered how antivirus software works? In a nutshell, traditional computer security software hooks into your operating system, and inspects every file or program before it is allowed to be open or run. Newer anti-malware technology keeps an eye out for unexpected system changes. Combining both methods will provide the best security. Let’s crack open the nut, and look at these techniques in a bit more detail.

The first malware detection method is commonly called “signature-based detection.” Any program contains unique blocks of code that identify it as surely as passages from a book identify what book you’re holding. The patterns of code which uniquely identify a malware program are called its “signature.”

Antivirus vendors compile databases of malware signatures and distribute copies to their users regularly. The antivirus program scans files on a user’s system looking for matches between each file’s code and those in the signature database. Matches are flagged as malware.

  1. I, too, received a call from a representative from SupportPlaza.com on August 23, 2013. I was told that my computer was going to crash and that they were going to help me to avoid this at a total cost of $39.90! I already had anti-virus protection from Norton and I was made to feel pressured to give them my money. When I called them back I got a runaround when I tried to get a refund even though they professed to be “refund happy” (their expression). I was given a lecture about having to do things that I don’t want to do. He did say that he would agree to give me a refund of $100.00. That was back in early to mid-September after I explained that I was on a limited budget. Here it is mid to late November and I still have not received this refund.

  2. Tech Support,

    I maybe put my last question in the wrong spot. I hope I get this right this time, so here goes!

    I was called Friday, 7/26/2013, by a Peter Coopre (his spelling).
    He claimed to be a certified Microsoft technician from SupportPlaza.com.
    His email supposedly is petercoopre213@supportplaza.com.
    Also, he can supposedly be reached at 1-866-856-4811.
    This phone number is good, and their website seems legit.

    He told me to run “msinfo”, then “running tasks” under “software environment”.
    He started by showing me a program called “csrss.exe”.
    He told me how evil this program is.

    He then told me about how I probably have thousands of these “EVIL”
    programs on my computer, even though I keep an updated firewall.
    (Trojans, Spy ware, malware, viruses, etc…).
    I also keep an updated AVG Antivirus Free Edition 2013.
    Plus, I also keep a few more security programs that I run occasionally as
    backups.
    I do this all per the suggestions from sites like yours, and a few others that I
    frequent.

    He also told me to run event viewer, and then go to “Administrative Events”
    under Custom Views”.
    This showed “3499” events, all marked “Error” or “Warning”.

    He told me that these “EVIL” programs get through no matter what I do.
    He said that he could remove the viruses for free, but I would still have the
    other “EVIL” security risks, and the “EVIL programs that he removed,
    would return no matter what I did.

    Of course, I already knew that he was trying to sell me something.
    The smallest package started $74.95 monthly, and went up from there.
    On the off chance that this company is legit, do I really have to pay to clean
    up my puter?

    I take both my Desktop and my laptop to my old business school once in a while,
    and let the tech support there tune it up, as well as clean it up.
    Should they have been alerted to all these “EVIL” programs?
    Does the techs at Staples and Best Buy know about these “EVIL” programs?

    Do I really have all these “EVIL” programs, as Peter claims?
    If so, what can I do about them?
    I use to think that I was pretty knowledgeable about these type of things.

    Is it true that these free security services, such as : AVG, Zone Alarm, etc…,
    are that infallible, and that I truly have to pay for security in order to be secure?

    Did this guy send all these “EVIL” programs to me in order to force me to use
    his service?
    Do you think that his service attacks a lot of PC users slowly, send them “EVIL”
    programs over many months, until they are ready to strike with scare tactics?

    Should I be scared?
    Do I need help?
    Can you help me, or at least give me some correct info?
    Inquiring minds would like to know.

    Your speedy response, concerning this matter, will be greatly appreciated.

    Sincerely,

    Neal H Figur
