Can an external backup drive pick up virus from an infected PC?

My current PC has a virus of some sort. Can this virus infect the external backup drive, and be transmitted to my new PC? If so, please advise how I can purge it of the virus before I transfer the data on to my new PC.

Only way is to connect to old PC and scan for virus on all drives

Do not connect external drive until you know it is clean. What virus ? what antivirus program?

have ou tried scanning with one of the online virus scanners like hitman Pro?

Thank you, Fruit Bat. I have done the scan as advised, and it has come out with "no threats found". I do not know if the scan included my external drive which was plugged into a USB port.

I am puzzled. My PC slows down to a virtual standstill during the first hour. The message "The following pages have become unresponsive. You can wait for them to become responsive or you can kill them" appears with practically every click of the mouse and everything freezes up for a few minutes. After about an hour everything works as normal. I was told there is a virus of some sort causing this. If this is not the case, how do I get my PC to work normally from the word go.

Also try running the free version of Malwarebytes.

Interesting name you have - anything to do with 230 Sqn by any chance???

Thank you, onthelimit1. The scan you mentioned gave my PC, including the back-up drive, the all clear. But the 'unresponsive' message still pops up. I am assuming that this is a PC fault brought on by age. My thanks to you and Fruit Bat for helping to put my mind at rest regarding my back-up drive.

Incidentally, sorry to disappoint, name has nothing to do with 230 Sqn; perhaps just a slight association with "Kita Chari Jauh" - we speak the same language.

  1. Software*

a) Clear out all temporary files and folders -- use CCleaner

b) Scan for malware spyware and viruses --Free Anti Spyware :- Malwarebytes Superantispyware

Free Antivirus software MicroSoft Security Essentials Avast

c) Clean the registry -- Use the tool in CCleaner its very safe and also allows you to back up the registry first.

d) Pagefile (Virtual Memory) -- Right click MY Computer - select properties - Advanced tab - Performance - advanced tab - Virtual memory click change, you can put the page file on a different 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 start up -- Start - Run type msconfig - start up tab- untick everything except for firewall, antivirus and antispyware

and the services that run in the background. see blackviper.com

2. Hardware

a) Hard drives /

i) IDE Channels: (Not required if you have SATA drives) 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 http://forum.digital-digest.com/showthread.php?t=61905 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, Vista or Windows 7 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.

b) Drivers 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.

c) Memory Your memory could be failing try memtest

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 will guide you through the process of selecting the correct memory. http://support.gateway.com/s/Manuals/Desktops/8509270.pdf for a guide to fitting memory.
