Hello Guys,
If you suspect your computer is infected by a virus (or any other malware), then follow the steps given below. If you suspect your problem is due to registry errors, get a good registry cleaner and PC optimizer from Intel Directory.
The procedure given below works for most malware (except for completely new, unknown or unusually malignant strains). It is better to complete all steps, so you can be sure that all traces have been eradicated.
Signs To Look Out For (Infections May Cause One Or Several Of The Following):
- Slow computer, and/or slow internet connection.
- Strange pop-ups or web browser redirections (beyond those expected from dodgy websites).
- Program failure, or inexplicable errors (even after a fresh install).
- System functions unavailable (eg: Control Panel, Task Manager, Internet Explorer).
- System giving a "RPC error", giving a window with a 30 second countdown to a restart.
- Excessive internet cap usage, i.e high internet traffic on your computer.
STEPS:
Step1. Run your virus-scanner, but beware, many modern viruses can circumvent (or hide from) anti-virus programs. Quarantine anything suspicious.
Step2. Make sure you are using a reputable antivirus. Some good free ones are Avira AntiVir, AVG, and Avast! NOD32 from Eset has the highest detection rate and lowest resource consumption, though it is not free.
Step3. In the event no viruses were found and your issue virus issue is still present follow these next steps.
Step4. Install Malware-bytes and update it, Don't scan for malware yet. Malware-bytes can be downloaded from here: http://www.malwarebytes.org/mbam.php
Step5. Other suggested scanners to run are “Spybot Search and Destroy” and “Superantispyware”.
Step6. Depending on the Virus you might not be able to install any software or do updates, if this is the case skip to step 7 otherwise continue to step 6.
Step7. Reboot into “Safe Mode” - Restart your computer and press F8 before Windows loads. Press F8 several times if you need to. Select “Safe Mode” from the resulting menu. Safe Mode disables much of the start-up routine (Continue to step 9).
Step8. Reboot into "Safe Mode with Networking" - Restart your computer and press F8 before Windows loads. Press F8 several times if you need to. Select “Safe Mode with Networking” from the resulting menu. Safe Mode with Networking disables much of the start-up routine but allows the use of basic web browsing, allowing you to access to download and update Malware-bytes, Make sure you select full scan option instead of quick scan.
Step9. Once in safe mode with networking download malware-bytes from their website, install it and update it.
Step10. Run your Malware Scanners - Run both the scanners sequentially, deleting any references found. CAUTION!! When deleting infected files make sure you are not removing important files you require, E.g. Microsoft Outlook uses “.pst files” for your email, and often some emails within this “.pst file” are infected. Virus scanners will delete your complete “.pst file” so your entire email Inbox NOT just a single email!!
Extreme Cases – “Safe Modes” Are Not Accessible
Step1. Have a boot disk. In these cases some anti-virus manufactures like Norton, AVG, Kaspersky and GData provide “Boot Discs”. These boot discs can generally be downloaded from their websites with all the latest updates included, so if possible download one of these boot discs and burn it to CD.
Step2. Reboot with disks. Once you have your Disc you want to reboot your computer/laptop and boot from CD. Many different branded computers/laptops have slightly different ways of booting from disc in most cases Esc, F9, F10 or F11 are used on start-up to access the menu option allowing you to select to boot from your CD/DVD Drive(it is suggested researching on the internet your device and which hotkey to use).
Step3. Scan by boot disk. When you have booted to disc run the virus scan from the CD. Remove and references found but be cautious in the files you delete as some files might be flagged that are a part of your email inbox.
Step4. Boot into your hard drive. Finally once these viruses are removed via using the boot disc, it is recommended to begin from step 7 again to continue further scans.
Step5. Consider asking professionals help. Very Extreme Cases – If you are at this point it is recommended seeking advice from professional.
Step6. Consider removing HDD. Final step if Norton, AVG, Kaspersky Boot Disc do not work. Remove your HDD/SSD from your Laptop /Computer.
Step7. Plug it into another PC that already has Malware-bytes installed, do not browse the HDD when you plug it in. Right Click and select "scan with Malware-bytes"(This is assuming the HDD auto-detects).
Step8. Learn how to plug HDD into another computer. If you have got to the stage where you have removed your HDD but are not sure how to plug it in the most simple and safe way I will recommend is purchasing a 2.5” or 3.5” external HDD enclosure and temporarily placing your drive in there so you can perform scans on the drive.
Step9. When scans are complete and viruses are removed, back up your data! Once you have complete your back up place the drive back into your computer/ laptop, start up the computer and see if the virus has been removed.
GOOD LUCK! HAVE A NICE DAY!!
