[Solved] Corrupt Win7 Registry Keys: Avast Pro Antivirus, Damaged Elements, Disable Programs, Java Update

Hello
I have Win7 installed

Avast Pro Antivirus signals me when scanning my computer
1. Damaged elements of the 681 issues (problems)
2. Essential 5.67 GB files
3. Problems with computer efficiency 1 problem
4. Software that slows down the computer. 9 programs in this show the level of deceleration.
They slow down the most according to Avast
a) Digital TV Tuner device registracjon application 80% (bar on the deceleration chart).
b) Windows media center store update manager 35%
c) Sidebar 35%
d) Steam 25%
e) Java 8 Update 151 (64-bit)
How to remove or disable these programs (not applicable to Steam).
Is it also the information of the anti-virus companies that do not try to draw the customer to buy their next product? Avast Professional Antivirus. Like their attention: "Your registry may be visible to others. Disconnect network access to the Windows registry to prevent the registry from being viewed." After scanning, their offer of this antivirus is released. Avast Pro had all these problems to solve .
I have a question: Should these damaged elements of the registry be removed. If so, what to delete in the key HKEY_LOCAL_MACHINE \ Software \ Lavasot \
there is a file named ab] (Default) Type REG_SZ Data: (value not determined)
Is the file "ab" or the "Lavasot" folder?
Because in the keys ended eg ...... \ Temp \ KiesTemporary \ wlanapi.dll
I think you need to delete the file "wlanapi.dll" which is in the key on the right.
Because, I would not like to mess up an experienced IT specialist with a hint.
One more question is how to disable network access to the Windows registry to prevent the possibility of viewing the registry.
Thank you in advance for valuable hints. Czeslaw

Thanks for the answer, but also for the rest. Slowing programs are also Avastu invention?
Digital TV Tuner device registracjon application of something like this I do not have in my computer.
How to disable eg Windows media center? I have it, but I do not turn it on. What to delete in the key HKEY_LOCAL_MACHINE \ Software \ Lavasot \
there is a file named ab] (Default) Type REG_SZ Data: (value not determined)
Is the file "ab" or the "Lavasot" folder?
I think it has removed CCleaner Professional, but it's good to know in the future? And how to disable network access to the Windows registry to prevent the possibility of viewing the registry.
As you can see, I do not know anything about IT. As I went to school, there was no known word "computer", and for machine tools controlled with perforated cards, it was only considered on interest circles for students of the Polytechnic.
And one more thing, what antivirus? Maybe at all? Microsoft constantly updates with the mass of current security. Regards Czesław

Once again, thanks. Cleaner removed unnecessary entries, uninstalled HD TV Tuner 2.5.5.
Will Ccleaner remove the key, or do I have to do it myself? If so, tell me how to find it. I will throw Avast Antivirus and I will introduce Microsoft.
The "Lavasot" folder contained a file named ab] (Default) Type REG_SZ Data: (value not determined). The Ccleaner program removed the entire "Lavasot" folder. Maybe I did it (I'm not sure).
How to disable network access to the Windows registry to prevent the possibility of viewing the registry? Is it necessary, or is it also due to the advertising of Avastu?
MSI has prepared a set of motherboard BIOS updates. Does this also apply to my CD? I have

After changing the graphics card on the Gigabyte GeForce GTX 1070 G1 Gaming 8GB GDDR5 256bit, it is necessary to update the Bios. Because it overwhelmed me, the site was changed in Olsztyn. From now on quite often when the computer starts up, the old logo appears on the screen, it is a hexagon
with spokes (something like a Mercedes sign). This symbol is on the packaging
GIGABYTE GA-Z77-D3H boards. Next, no key, or the combination of Ctr, Alt, Delete does not work. A hard reset turns off the computer. Then turn off the power and wait about 1 to 2 minutes gives you the ability to run a compa. Sometimes this action should be repeated 2.3 times. Frequently, the GIGABYTE logo appears and the computer starts correctly. According to a technician, this may be due to a weak power supply. I have ModXStream Pro 750W power supply. Additionally, I give

I usually work on SSD 240GB + SSD Disk 120 GB and sometimes + TB Disk. As if you could help the old IT amateur.

Please, close the topic.
I solved the matter by giving up Avastu.
Avast does not answer questions. It does not offer any help to users, and it constantly harasses customers for different protection options, apparently more and more perfect.
Therefore, using the hints, I uninstalled the program, and I am not answering the taunts.
