When a new virus, or Trojan hits the Internet there is a good chance that it will be infected by dozens, hundreds or even thousands of computers is very high. 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, many AV programs are plagued by a range of serious issues that limit their effectiveness. If you’re using any of these programs you must be aware of these problems so that you can take the necessary steps to safeguard yourself.
First, many anti-virus programs cannot detect all viruses and Trojans. This is because of the fact that virus writers and hackers constantly create new varieties of malware. Anti-virus software isn’t able to guarantee 100% security.
Another issue is that many commonly encountered software issues can produce symptoms that look like virus-related issues. It is essential to be aware of other causes for problems, before you suspect that a computer has been infected by a virus. Some malware could display pornographic images in the screen or articles of news. A related symptom is when the screen keeps home showing ads for websites that you do not visit.
