If a virus or Trojan reaches the Internet, the likelihood that it will infect dozens, hundred or even thousands of computers is extremely high. This is especially true of network worms. This is why it is important that antivirus software vendors are in a position to release updates for protection quickly and efficiently to prevent these computer pests from spreading.
Unfortunately, AV programs suffer from many major issues that compromise their effectiveness. You should be aware of the issues if you use any of these softwares so that you can protect yourself.
The main issue is that a lot of anti-virus programs can’t detect all viruses and Trojans. This is a direct result of the fact that hackers and virus writers are constantly creating new types of malware. This means that far from all anti-virus software sold off the shelf or on the Web can provide a protection of even a fraction of 100 percent.
A common software issue may cause symptoms that look virus-related. It is therefore essential to always check for more typical causes of issues before you suspect that a system is infected by a virus. For instance, certain kinds of malware can cause pop-up windows to pop up on your screen that shows pornographic images or news articles. Another symptom is that the screen keeps showing ads for websites you don’t visit.
