Ransom ware is a variety of malware that, once it infects its host-machine, at least says it’s encrypted the data on or locked its victim’s machine in some other way. The malware then informs the infected user that he or she must pay a ransom in order to unlock their files. Of course, there is never any guarantee whatsoever that paying the ransom will unlock anything. In this case the Cryptolocker really carries out the threat, The virus encrypts files stored on local hard drives and mounted network drives using public-key cryptography, and then displays a message saying that the files will be decrypted by a 2048-bit RSA key pair if a fee is paid through an anonymous payment service by a specified deadline, beyond which decryption is no longer possible. There is no way to decrypt the key.
US-CERT issued an advisory this week warning businesses and consumers of the risks presented by CryptoLocker, which has been on the radar of security experts since late October. US-CERT said infections are on the rise and urge victims not to pay the ransom, instead report it to the FBI’s Internet Crime Complaint Center.
How the virus works – What does it steal from you? Who does it Target?
CryptoLocker installs itself to the Documents and Settings folder on your system and then proceeds to search for specific file types like Microsoft Word Docs or Adobe PDFs. It applies an asymmetric encryption which requires both a public and private key to unlock. The public key is stored in the virus itself and is used to encrypt the files. The private key is hosted on the hacker’s server.
We have noticed a high infection rate here in Baltimore County as well as the surrounding metro Baltimore area. This is serious business for these thugs and for the first time this type of attack is being considered organized crime.
How do I get it?
- As an email sent to company addresses pretending to be from customer support from FedEx, UPS, DHL, etc. The virus is attached to the email, usually labeled as a tracking number.
- In PDF documents that are attached to emails.
- Via hacked websites that can exploit computer vulnerabilities to install the infection.
- Through Trojans that pretend to be programs you need to download in order to watch videos online.
Some versions of CryptoLocker are reportedly capable of affecting not only local files but also files stored in Removable Media such as USB sticks, external hard drives, network file shares and some cloud storage services that are able to sync local folders with online storage. The US-CERT notification also warns that the malware can jump from machine to machine within a network and advises that infected users remove affected machines from their networks immediately.
Can Baltimore PC Repair remove the virus?
The techs and engineers here at Perry Hall PC Repair have had success with removing the virus but at this point it is impossible to retrieve the encrypted files so honestly the best practice is to wipe the hard drive and start over.
IMPORTANT SAFETY INFORMATION
- Beware of attachments – Always look at your attachments. If you get an email with an attachment from any sender you don’t personally know don’t open it. If you get an attachment from people you do know, but it isn’t something they would normally send, don’t open it. For all other attachments, try confirming that the file attached is in fact legitimate by asking the sender.
- Backup your data – Be sure to always backup your data on a regular basis. If you backup files on a daily or even weekly basis and are infected, you can easily wipe your hard drives and start again without losing much in the way of data.
- Know what to do if infected – If you are infected the first thing you should do is disconnect from the network to limit the chance of the virus spreading to other systems. If you have backed up your system and data, you can probably revert your system. If not, your best plan of attack would be to contact us to see if we can help, as we may be able to get around the encryption or even delete it

Computers require maintenance on a regular basis. Maintaining and repairing your computer ensures it operates error-free instead of making you frustrated. Read these free computer repair tips:
Defragmentation of the computer system is necessary to prevent it from slowing down on performance. Neglecting this results longer wait times when searching for files and opening programs. Defragmenting also streamlines bits of other programs and files that have been deleted or uninstalled, and that have been distributed randomly in the system, taking up unnecessary memory space.
Installing anti-virus software helps prevent system crashes and theft of private information by online criminals. Many cyber-threats such as viruses, trojans, spyware could cause problems if left unchecked. It’s necessary ensure that antivirus programs are updated to deal with the newest cyber-threats.
Delete unnecessary temporary files and programs from the computer. These junk files waste hard disk space which also slows down performance. Also remove software programs that you no longer use.
PC physical cleaning keeps the machine free from dirt and dust. Over time tiny particles and dust collect on the machine which cause it to overheat and malfunction. When working on a PC it’s best to keep food and liquids away from it.
Ensure the machine’s programs and software are updated. There are numerous software that can do this automatically. The main thing to remember is that computers need care and attention to work properly. These are some basic but important tips regarding computer repair and maintenance that users ought to keep in mind.
If you are unsure about how to do any of these tasks yourself, don’t risk damaging your computer system. Consult a professional computer technician. Contact Perry Hall PC Repair for certified computer technicians to fix any computer problem.
If you don’t have antivirus software installed, then you need to get on this right away. I would highly recommend Vipre Anti-Virus If you are looking for a good antivirus. The second part of this is that you need to keep this software up to date and you need to run scans regularly. Most good antivirus software packages will automatically update themselves. However, it is a good idea to check that this is happening. When it comes to scanning, it is a good idea to scan every week or so. By keeping your virus protection software up to date and by scanning often, you can make sure you catch any threats before they can wreak havoc on your PC.
Be Careful When Opening and Clicking Links Within Emails
Opening a bad attachment or directly clicking on a virus in an email are two really common ways to get a virus. There are quite a few ways to avoid this. First, be really careful opening emails that have attachments from people you don’t know. Second, if you open an email, you don’t recognize the sender, and the email itself really doesn’t make sense, then don’t click on any of the links in the email. In this case, it is best to just delete the email and move on. Last, if you are not with a solid email provider like G Mail, Yahoo Mail, etc, then you may want to think about switching. These services do a great job of filtering out any viruses before they even get to your inbox.
Be Careful When Browsing the Internet
Another really common place to get a virus is from a bad website. We have all been there, we have clicked on a link or a result in Google search and we end up at a website that just doesn’t look trustworthy. This site is trying to get you to download stuff, has tons of popups, and won’t even let you go back. In most cases, you are still OK. However, what you do next may determine if you get a virus or not. First, see if you can go back or even see if you can close out the browser window. If it doesn’t let you, you can try to close any popups or notifications using the “X” or the cancel button. If you still can’t get away from the bad site, you can use the task manager by pressing CTRL+ALT+DEL to manually close your browser task. The big key is that whatever you do, don’t allow your browser to download anything. Most browsers today will ask if you are sure that you want to continue with a download. This is where you make your last stand against the virus.
To go along with this, it is best to just avoid certain types of sites. First of all, avoid public torrents and public torrent sites. These are well-known virus farms. You may also want to be careful around any type of adult sites or any low quality streaming sites. I am not talking about YouTube here. I am talking about sites that stream a specific TV show or channel illegally. These types of sites might have malware as well.
One last thing to look out for when browsing is fake “download”, “play now”, “play”, etc buttons. Be really careful around these. Keep an eye out for these on sites that you particularly don’t trust. Also, while on the topic, don’t fall for the “Your computer is infected” ads or popups as well. These are usually a trick to get you to download a virus. If you see one of these and you are unsure, close it, then open up your virus protection software and run a scan. This will tell you if you are truly infected or not.
Be Careful When Downloading Programs or Files
There are many times when you really just need to download a program or file from the Internet. If you do this correctly, then there is no issue. However, the key here is that when you download something, make sure it is from a trusted source. Downloading software directly from the software manufacturers website is one good tip. For example, if you need to download iTunes, download it from Apple itself, not some third party distributor. The only time you should download from a third party site is when the site itself links to the third party site for the download.

A lot of people always ask us “What security program do you recommend?” and usually they follow up by saying “I was thinking of getting Norton”. Once upon a time we would have said its easy to use and has great protection, but that was a long, long, long time ago not today!
One reason why we don’t recommend Norton is because it is a jack of all trades and a master of none.
The current Norton program has the ability to do about 20 different things such as parental controls, email protection, and performance alerts.
Just looking at the features that Norton offers it may seem like a good deal but its unfortunately not. Many of the features that Norton offers are not as robust as they need to be and so they are simply attempting to do far to much. All of these extra features are more then the average computer user or business user actually needs, yes to much of a good thing is bad at times.
One of reasons why I don’t recommend Norton:
It slows down computers way to much, in my opinion Norton has become bloated and has way to many things that in reality most people won’t ever use. What people really need is a good security suite and not a program that does 20 different things.
If you currently use Norton I suggest that you try and see what I’m talking about by removing the program (do not go online without internet security), once the program is removed you will see an incredible boost in speed and even after replacing Norton with another security program you computer will still be much faster.
The even bigger reason why I don’t recommend Norton:
I have seen far to many computers infected with viruses that have Norton protection on them. In fact over 70% of the machines we remove viruses from have Norton or McAfee installed. There is no point in paying $79.99 for a security program if you end up having to go and take your computer for a virus removal.
We Recommend a Multi -Layered Approach to system security encompassing of a Solid Anti Virus, a Good Anti Malware, and a dependable Anti-Spyware program combined with custom browser settings
