Having installed one antivirus software on your computer is not enough these days. The PC should stay protected at all times. Most PCs come with a main antivirus software. This could stop due to technical reasons. It could also expire. There must be another antivirus software in the computer to keep it protected when the main software is down. An antivirus should be able to scan the PC for viruses so that if there is a virus in the computer, it can be located and killed.
The main features required from antivirus software are to keep the PC protected by installing all the relevant security updates. These updates are also necessary as the virus could spread to many parts of the computer and hide itself from databases so that it cannot be detected. The existing software might not have enough features to protect it from these even more dangerous viruses. This is why there needs to be complete protection. This is only possible if the antivirus is capable enough of installing new security updates.
Viruses can creep inside your computer through USB flash drives. If you work in the business sector, then you probably can’t avoid plugging in various USB flash drives. Some of these viruses are hidden from databases. A not good enough antivirus will not be able to detect this hidden virus. However, as a second layer, the smadav pro is known for the way it is always active round the clock. It can locate the hidden files as well and then later combat them.
The antivirus should be able to protect from malware on the internet such as those attached to emails and in download links. It is better to not click on them but keep multiple antiviruses.
