Antivirus has been marketed for years as a commodity similar to toothpaste, detergent or automobile. However, despite being such an everyday product antiviruses aren’t free of flaws and issues.
Antivirus programs simply cannot keep up with the variety and number of new malwares that are released every single day. It’s an arms race and far from all antivirus programs available off the shelf or on the internet actually offer an amount of security that is close to 100 percent.
Another problem is that Trojans and viruses are able to alter the software on your computer so that it cannot detect them. This may happen because the virus alters the settings of the antivirus program or it’s ability to create a false positive by exploiting one of its own functions or features.
There are many instances when the antivirus software does not recognize files even if they are malicious. The antivirus software hasn’t yet had a chance of adding the www.pceasyblog.org/best-buy file to its database. In order to do that, it needs to analyze the new file and compare its contents with known malware-related files in the antivirus’s database. This is a resource-intensive and lengthy process. The slower it runs, the less accurate is the detection. The antivirus must also install interceptors that look at system events deep inside the computer’s kernel order to send the data to its engine.
