Malware & virus damage · recovery

Struck by malware? What you lost is usually still there.

Most malware will hide, scramble or remove links to your original data rather than genuinely erasing it, so in the majority of cases it is all still sitting on the disk. We make an image copy of the affected SSD, hard drive, card or USB stick in isolation, pull the files from this image and deliver them to you clean: the malware never runs once while we do the recovery.

Stop using the infected device — right now.

Every hour an infected drive keeps running gives the malware more opportunity to damage or delete your files, and more chance of spreading to other equipment you plug in. Repeated scans by your antivirus software are just as risky, as they may quarantine or destroy the very files you are trying to recover. Shut the device down, keep it away from your other computers, and contact us: we recover your data from an isolated image of your storage media without the malware ever executing.

// what malware does to data

The shapes malware damage takes.

When a drive won’t open its files, the files have almost never genuinely gone. What has usually happened is damage to the file structures, missing pointers or flipped attributes. Show us it’s yours, and here is the sort of trouble we untangle most weeks.

▤Files and volume corruptedMalware can overwrite file headers or corrupt the file-system infrastructure (the $MFT on NTFS, or the FAT tables on a card or stick), leaving a drive that mounts but won’t open its files, or won’t mount at all.CommonCorruption◌The shortcut (hidden-file) virusA common infection on USB sticks and memory cards changes your actual files to hidden and system status, then creates .lnk shortcuts in place of your originals, often along with an autorun.inf file. It appears as though the files were deleted, but in fact nothing has been deleted.USB & cardsHidden⊟Files deleted or overwrittenSome strains simply unlink files, whereas the nastier ones overwrite them. If a file was merely unlinked, its clusters remain unchanged until something reuses them, so we can carve that file back out of unallocated space.DeletionWiper▣Boot-sector infectionIf a bootkit resides in either the master boot record (MBR) or the volume boot record, it can stop a disk from booting or being read at all. We image the disk read-only and recover the file system located behind the infected boot code.Boot sectorMBR◳Damage from the clean-upOften, when antivirus software removes malware, it also sweeps up the files you needed. We retrieve these files from the quarantine vault or from the free space they were moved into.CleanupQuarantine◍System won’t startWhen malware has damaged Windows’ own files (the registry, boot configuration and drivers), the computer will fail to boot even though your data is intact. In this instance, we copy your data directly from the disk instead.SystemWon't boot

// our recovery process

Inside a malware recovery.

One rule applies to the whole process: the infection never runs. First we copy your device in isolation, second we extract your data from that copy, and third we clean it and hand it back, in that order, every time.

01

Free diagnostic

Talk us through what happened, and we establish exactly what the malware did to your data (whether it was corrupted, hidden or deleted) and provide you with a written quote, usually within 48 hours.

02

Copy it, sealed off

We make a read-only image of your device on a write-blocked, air-gapped rig, so at no time can the infection execute, reach the network or spread to anything else.

03

Recover from the copy

With the malware frozen, hidden and system flags are removed, directory entries are rebuilt and any data that was deleted is carved back out of unallocated space.

04

Rebuild what’s broken

A damaged $MFT, cross-linked clusters or a lost partition table: we repair them, or rebuild them from the volume’s own spare copies, until your data becomes accessible again.

05

Scan, then verify

All recovered data is scanned against current signatures and cleared, then opened and checksum-matched, so that nothing infected or broken is returned alongside your files.

06

Return it usable

Your data comes back on new media, organised and ready to go.

07

Backup Drive or Download

It is posted back to you on an external drive, or downloaded using our free download service for up to 75GB, whichever you prefer.

// what we recover from

Any device. Your files back, clean.

All types of infected storage devices can be recovered, including laptop and PC drives, SSDs, hard drives, external units, USB sticks and memory cards. Your files are recovered from a sealed-off copy and handed back clean, without the infection ever being allowed to run.

// frequently asked questions

Malware recovery — common questions.

Questions people commonly ask before sending in a virus or malware infected drive.

Almost always. A virus does most of its damage to the pipes rather than the water itself: it corrupts file-system structures such as the $MFT on NTFS and the FAT tables on flash, or rewrites headers, while the actual file contents stay put. Working on an isolated copy, we repair or rebuild the plumbing, recover deleted files from free space and return everything with the infection removed.

Not at all. This particular pest, which you catch from USB sticks and memory cards, merely flags your files as hidden and system and creates .lnk shortcuts (plus an autorun.inf) over the top. It never deletes your files. Once you reset the attributes and remove the shortcuts, your files are exactly where they were before the infection.

No, they will not. Our recovery takes place in a sealed-off environment and the results are scanned before they leave us, so when you plug the recovered data back in, you will not reintroduce anything to your machines.

Rarely. A damaged boot chain (the MBR, boot configuration, registry and the system files Windows relies on) prevents the machine from booting without affecting any of your documents. We bypass the operating system completely, create an image of your disk and then retrieve your files directly from that image.

Often. When an antivirus program quarantines a file, it actually places an encoded copy of the file in its vault and unlinks the original. A straight deletion just leaves the blocks in place until something else is written over them. Either way, there is a good chance of recovering the file from either location (the vault or unallocated space), provided the drive is not used in the meantime. Stop using it and call us.

What we do is pull your data off and hand it back to you clean. The infected system is never booted during our process (your files are taken from an image and scanned in isolation), so the copy you receive will not contain any malware. However, cleaning and rebuilding the original machine is a different job altogether.

The cost of a logical recovery starts at £300 + VAT. The diagnostic beforehand is free, and in most cases you only pay if we recover your data. If, in addition to the malware, your hardware also turns out to be failing, we will give you any higher figure in writing before proceeding.

Practically anything that stores files: the internal drives in laptops, PCs and Macs, standalone hard drives and SSDs, external and portable units, and flash of every kind, from USB sticks to SD, microSD and CF cards.

Most recoveries take one to three working days, and often less. Our free diagnostic is usually completed within 48 hours. If time is of the essence, please let us know and we will try to move it up our queue.

There are two ways to get it to us: bring it to our Guildford premises on a weekday between 9am and 5:30pm, or post it fully insured. Seal the package securely and include your contact details inside (name, address, phone and email) so that we can log it. The free diagnostic and a written quote follow before we touch anything.
