In Medical Science, a virus (latin word for “poison”) is an infectious agent made of genetic material from either DNA (Deoxyribonucleic acid) or RNA (Ribonucleic acid). It invades cells to replicate and/or modify its functions. A computer virus is no different. A computer virus is a malicious program compose of codes that attaches into an existing program to replicate (make copies of itself) and modify its functions.
It is possible that your PC could get infected by more than one virus. This is common if you are browsing malicious websites or had been installing untrusted programs on your computer. There are also computer viruses that when executed, downloads more viruses into your computer; thereby complicating the problem and making it even more harder to clean your PC.

Run adwcleaner.exe by double-clicking it. When prompted, click on Delete then confirm each time with OK. Your computer will be rebooted automatically and a text file will open after the restart. AdwCleaner is an adware cleaner and this tool will ensure that aside from malware, your PC is also free of adwares. It is important to remove adwares as well since they can sometimes be sources of infection.
It is also worth noting that in OS like Windows XP and later versions of Windows, there is a System Restore program that was meant to fix your computer in case it gets messed up. What it does is that it creates backup restore points from which you can restore your system from. The problem with this program, however, is that when you get infected and you use it to create a restore point, it can also backup the virus along with the other regular apps. So when you restore from a previous state during which the PC was still infected later on, it could also restore the infection along with it. For this reason, it would be prudent to also delete the infected restore points.
The final step to remove multiple computer virus from your computer involves some little housekeeping. Let’s start by removing the AdwCleaner.
