It is highly likely that an upcoming virus or Trojan will infect dozens or even hundreds of computers, or thousands. This is especially true for network worms. Therefore, it is essential that antivirus software providers can release updates quickly and effectively to prevent these computer bugs from becoming widespread.
Unfortunately, a number of AV programs are plagued by a number of serious issues that limit their effectiveness. If you’re using one of these products, you should be aware of these issues, so that you can take steps to protect yourself.
The main issue is that a majority of anti-virus programs simply cannot detect all viruses and Trojans. This is because hackers are constantly inventing new malware. Anti-virus software is not able to guarantee 100% security.
Another issue is that common software issues can result in symptoms that look like viruses-related errors. Therefore, it is essential to be aware of the more common reasons for problems before deciding that your system is affected by a virus. For instance, some kinds of malware could cause pop-up windows to appear on the screen, which displays pornographic images or news articles. Another indication is when the screen constantly displays ads for websites you don’t visit.
