If your computer became infected with viruses, spyware or any type of malware and it is difficult to disinfect it, we recommend that you make the following indications, for an effective elimination of these computer parasites.
1. Deactivate ‘System Restore’:
Disable the “System Restore” (Windows 7).
Disable the “System Restore” (Vista).
Disable the “System Restore” (XP).
After cleaning, you can activate it again.
2. Show hidden files and extensions:
For “Show hidden files and folders and extensions for known file types”, follow these instructions.
3. Restart in “Safe Mode” (this point only for Win 7 / Vista / XP / 2000):
Start in “Safe Mode” (7 / Vista / XP / 2003/2000).
4. Proceed to cleaning:
Empty the recycling bin.
Delete all temporary files:
Uninstall suspicious programs:
Run your updated antivirus and scan your entire PC.
Run your updated antispyware and analyze your PC.
Install a firewall temporarily (Optional):
It is likely that the virus or the hacker wants to try to attack your computer again, to avoid this it would be advisable to install a firewall even temporarily.
Install the Microsoft patches (Optional):
Install critical and important Microsoft patches. You can see the latest bulletins issued by Microsoft from here or from the official website.
Note: This can be fast or slow depending on your Internet connection. Some time ago Microsoft added a validation system, that is, only users with a legal license will be able to install these patches.
If your network was infected, perform these procedures on each of the computers by first disconnecting them from your network and the internet.
If after the disinfection, Windows is unstable (error messages, slowness, etc.), then it is recommended to repair the system with these indications. To have the best results use a professional for computer virus removal in Huntsville.
1. In spite of making all these indications my PC is still slow, why is this?
If after Windows disinfection was unstable, it is recommended to repair the system with these indications. If it is still unstable, it may be that the slowness is not due to viruses, but to the applications that are loading when you start your PC. It is recommended to uninstall programs that use less or that are expired, or simply to prevent them from loading when turning on the PC with utilities such as Microsoft autoruns.
If in spite of this the system is still slow, it is likely that the virus has damaged some important file, for that it is recommended to format and install the system again.
2. Have I removed the virus from my PC but I get messages when I turn it on, will it still be infected?
Most viruses are added to the system registry “Regedit” (a path key), in the “System Startup Files” or in “Start” of the Start Menu to auto-run every time we turn on the computer . When these viruses are eliminated these additions could continue in the system showing possible error messages (without this means that the PC remains infected). What you can do is remove them manually for example with the Microsoft autoruns utility.
