It is very likely that an upcoming virus or Trojan could infect dozens, hundreds of computers, and possibly thousands. This is particularly true for network worms. This is why it is imperative that antivirus software providers are able to release protection updates quickly and efficiently to stop these computer bugs from spreading.
Unfortunately, AV programs suffer from many major issues that compromise their effectiveness. Be aware of the issues when you use any of these programs to protect yourself.
First, many anti-virus programs cannot detect all viruses and Trojans. This is a direct consequence of the fact that hackers and virus writers are constantly creating new types of malware. Therefore, far from any anti-virus program sold off the shelf or on the Web will provide a protection of even a fraction of 100 percent.
A common software issue could also produce symptoms that look virus-related. It’s essential to be aware of the more common causes of problems before suspecting that your system may be affected by viruses. For instance, certain types of malware can trigger a pop-up window to appear on the screen that shows pornographic images or news articles. Another indication is when the screen keeps showing ads for websites that you do not visit.
