What is ransomware and how do I protect my PC from Petya?
Either him or it
Please my gentle with me I am not tremendously technical
I have done:
Currently I have:
Used 33.6 GB
Free 19.4 GB
Used 15.4 GB
Free 38.2 GB
But it is very very slow - it's an Acer (& I'm not very good at this)
Could anyone help?
Is that 1.60 GHz & 896 RAM?
a) Clear out all temporay files and folders -- use Crap Cleaner click here
b) Scan for malware spyware and viruses --Free Anti Spyware :-
Superantispyware click here
Malware removal tool click here
Free Antivirus software
Avast4 click here
AVG antivirus click here
c) Clean the registry -- Use the tool in Crap Cleaner its very safe and also allows you to back up the registry first.
d) Pagefile (Virtual Memory) -- Rght click MY Computer - select propeties - Advanced tab - Performance - advanced tab - Virtual memory click change, you can put the page file on a differnt drive (if you have one), click custom size and set Initial size to one and a half times the amount of memory you have fitted i.e. 512MB memory = set to 768MB, set maximum to double your memory amount i.e. 512MB memory = 1024MB click ok.
If your hard drive is full and there is not enough room for the pagefile this can slow down, freeze or even cause the PC to crash (restart).
e) Cut down on the programs that load at startup -- Start - Run type msconfig - startup tab- untick everything except for firewall, antivirus and antispyware
and the services that run in the background. click here
a) Hard drives /
i) IDE Channels:
Check the transfer rate, you need to have the transfer mode set to DMA not PIO.
Right click My Computer - Properties - Hardware - Device Manager - Expand (click the + ) IDE ATA/ATAPI controllers right click Primary Channel - Advanced Settings Tab -
If transfer Mode is PIO then follow the instructions at click here to change.
ii) Check for errors and defrag your hard drives -- My Computer - select drive - properties - tool tab - Error checking / Defragmentation.
ii) If you are using Windows XP or Vista, it's a good idea to convert your system drive to the NTFS file system if you have not already. In addition to providing numerous security and data recovery improvements over FAT32 (the file system of choice for Windows 9x/ME and XP Home) it can also speed up your system slightly.
In fact, the only real reason for sticking with the FAT32 file system for any of your data is if you have more than one operating system on your PC and the other OS's can only see FAT32 partitions (as would be the case with Windows 98, for example, which is incapable of reading NTFS data).
To convert your drives to NTFS:
Right click on 'my computer' and select 'manage'
From the computer management window, expand storage and select 'disk management.'
Using the 'file system' column of the upper pane of this window, you can easily check what file system each of your logical drives is using. Make a note of this information.
Now open a command prompt window by going to 'start\run' and typing 'cmd'
To convert a disk to NTFS, type 'convert (drive letter): /fs:ntfs'
So for example, if you were going to convert your C: drive, you would type 'Convert c: /fs:ntfs' at the prompt.
Obtain the newest drivers for your hardware
This may seem a bit obvious, but keeping your system's drivers up to date can give both your performance and stability a boost. Video card manufacturers release updates especially often, and these can often give "significant boosts" to gaming performance as video card in question is "optimized."
Don't neglect the other components of your system either. Your motherboard manufacturer may have released newer versions of its Input/output drivers for your board, and sound cards and other peripherals can also benefit from newer software.
Add more physical memory, this of course means opening the "box" and fitting a memory module, make sure you buy one that is suitable for your PC. Crucial .com click here will guide you through the process of slecting the correct memory. click here for a guide to fitting memory.
Fruitbat - I'm not that quick - I'll do a bit at a time
Is your crap cleaner the CCleaner I used?
I have AVG (9 I think) & it's uptodate (paid for) do I need the other 2 you suggested too?
I'll read the next bit now
On the startup tab of the system configuration utility there is nly AVGtray & ePower_DMC
Should I untick the ePower_DMC?
katymac, ccleaner is the same yes.
no no need to untick that
I am doing the Malwarebytes thing now
& then I'll look at
"d) Pagefile (Virtual Memory) -- Rght click MY Computer - select propeties - Advanced tab - Performance - advanced tab - Virtual memory click change, you can put the page file on a differnt drive (if you have one), click custom size and set Initial size to one and a half times the amount of memory you have fitted i.e. 512MB memory = set to 768MB, set maximum to double your memory amount i.e. 512MB memory = 1024MB click ok.

That looks quite complicated
katymac, don't worry, its not complicated. I have followed you here from the MN thread, i don't think recommendations here so far will find out the real problem yet though, they are pretty similar to type of stuff you've already tried...
