Getting rid of computer viruses

How many Windows user never encounter a virus? Unless you’re not connect to Internet. Chances are, all Windows users knows about computer viruses, but little are aware of how to solve it.

When you’re surfing online, be it online shop or insurance online, you are risking your computer.

Here are a few steps I find useful, according to my experience

Turn off system restore

Once you encounter a virus, turn off the system restore at once. Some virus can trace back into system restore and ruin all restoration the computer generated. This may result a total missing of files and folders.

Safe mode

When you log into safe mode, a lot services/processes will be stopped. Network is one of them. Some viruses depend on certain services/processes to work probably. There are times I log into safe mode, and delete the virus manually, and it works!

Anti virus, please?

There are a few users don’t like to install anti-virus programs, they find it resources consuming and depend heavily on System Restore. The bad news is, if you don’t have an anti-virus program to warn you about virus, the virus may already ruin all your restoration. Formating become the way to kill the virus as well as your hard drive.

After a few experience of small and big viruses, I started to be very caution of websites I surf and program I download. Majority of computer users don’t like to read, especially a warning pop-up. They will blame it on Windows that is not working well, when the fact is the warning is to tell them what to be caution for.

These steps is no guaranteed though, but it may works under some virus.

Viruses again

This would be the second time I’m getting virus on this computer. First time was a small one, wherre AVG can kill it without a problem, the virus did not appear anymore after the vault. However, this time, this viruses were running too much, too much on external disk (Weird thing is it happen on my pendrive only, not on my external HDD though). Some people call it as s07[1].exe, but it usually appear with another 2 more exe files, they all work together in document, local setting in some temporary file. So once you plug in your pen drive, where it has an autorun.inf file in it, those viruses ran into the file and change the file so they can work.

It’s a Malware from my research on the internet, and they recommended lots of trojan removal softwares, which I never bother to install. And this is the easiest way to completely delete them, my way

1, Open Notepad, write nothing save as autorun.inf
2, Plugin your pendrive (Your Antivirus might catch them again)
3, Copy and paste autorun.inf to your pendrive, replace it!
4, Right-click and properties autorun.inf and check the “Read-only”
5, Scan you computer, make sure your Antivirus lock them or delete them.

Done! This is to prevent the virus to be able to re-write the auntorun.inf. For some reason, they just don’t die so easily Now, you have a cap on your pendrive, use as usual. But honestly, I always don’t recommend people to exchange file with pendrive, exchange using email is the priority for me

Free Anti Virus Tools

All antivirus tools are not perfect, they miss things or can be purposefully damaged. Here are some free tools that help you supercharge your AV utility and keep your Windows computer clean. Of course not all PC has a metal roofing, I don’t think Firefox can help on preventing when online too (Well, maybe on surfing the web).

BitDefender Online Scanner is a web application (requires Internet Explorer) that scans your system’s memory and all files, detecting and removing infections. Perfect to check if you regular antivirus app missed a malware infection. Also I recommend ThreatFire Free. ThreatFire is a free download that supplements (now don’t go deleting your AV engine just yet) your regular antivirus program. It’s cool because it has “behavioral-analysis protection” that basically attempts to identify Trojan horses and other malware based on how your PC operates. Those with “slowing” computer may want to check this out!

Unknown Virus

Tell me what is this virus? From China? I’ve notice this long time ago, most anti virus softwares don’t detect any made-in-China viruses… I think it’s about time for them to take a little acknowledgment on China virus.
