I immediately performed a full scan of the hard drive with update-to-date MSSE and it found nothing suspicious. This immediately resulted in slow-down of the computer (especially while surfing the internet) and the start of ghost audio (e.g., like listening to FM radio ads with bad reception) playing constantly after connecting to the internet, and this ghost audio would not stop unless the computer was restarted, and then would always immediately start again after reconnecting to the internet by opening MS Explorer browser. Recently my wife got some sort of pop-up while using Skype, and she clicked on a "No Thanks" button in the pop-up window. I purchased the computer new several years ago, and it is stock (i.e., no hardware mods). Alternatively, you can specify that you should be asked what action to take for each detected threat, or you can specify that no action should be taken.įinally, click on “Schedule Now” and the scan will start automatically as soon as the system is restarted.I have an Acer AX3810-U1802 desktop running 64-bit Windows 7 with Microsoft Security Essentials (MSSE) as the only virus/malware software. avast! can automatically attempt to repair the file, move it to the virus chest, or delete it. You can also specify what action should be taken if a threat is detected. The higher the sensitivity, the higher the “pass mark”, therefore the higher the chance that a file will fail the heuristic test and will be reported as a potential virus.īy default, the program automatically scans for potentially unwanted programs and also scans inside archive files, but either of these features can be turned off by unchecking the relevant checkbox. The heuristic analysis comprises a large number of tests based on typical virus content or behavior and the sensitivity level will determine how many tests would have to be failed for a file to be considered as infected. You can adjust the heuristic sensitivity by clicking on the orange bars to change the sensitivity to Low, Normal or High, or you can turn it off completely. In the “Settings”, as well as scanning the boot-sector, you can also specify other areas to be scanned automatically when the system restarts.
This is useful if you suspect that a virus may have been installed on your computer, as it will enable the virus to be detected before it is activated and before it can do any damage to your computer. when it “boots”, before the operating system is active.
It is possible to schedule a scan to be carried out automatically when the system restarts i.e.
