malware

Richard signs onto a web pages and when he goes to sign out, it won’t let him. He can’t even scroll back up to the top. Leo says that’s likely a javascript error. There is some malware that does “cross site scripting,” which captures mouse clicks and will cause a similar issue. Leo recommends running both a full scan of his Anti Virus software, and then adding a full scan from Microsoft’s Malicious Software Removal Tool.

Rootkit Revealer from Microsoft’s SysInternals site may also help and he can always reset his browser, clearing cache and history.

When running AOL, Mark's mouse goes crazy, but when he goes to AOL via another web browser there is no issue.

Rick says his XP machine got bit by malware, and the utility he used to fix it was also malware. Leo says that it may not be, but modern malware attaches itself to critical system files, causing the drivers to disappear and lose internet connectivity. It's likely the malware utility didn't even fix it and more malware is being installed without his knowledge.

Laurie downloaded some tax documents from DocStock.com and now she's having a variety of problems on her computer. Leo says that docstock.com is a legit site, but it's possible their website got hacked or a malformed PDF was installed onto the site. The strange tool bar in her browser is a bad sign.

Laurie could get someone to remove it (and she's tried), but it's likely there's other stuff going installed and going on as well. So the only way to really be sure is to back up the data, format the hard drive, reinstall Windows from a known, good source, and run updates.

Mike's wife was on a site a few days ago and now there's a search bar in Internet Explorer that they don't want. Leo says it's likely a piece of malware, but it may simply an issue of just removing it from add/remove programs. But it also could be something more malicious. There are things called "zero day exploits" where Microsoft announces a bug they are fixing and hackers took advantage of it the same day it was discovered. If he can't run Windows update, then it's something that needs to be removed. He won't be able to run system restore either if that's the case.

Arthur's sister got a call from Microsoft to remove a virus from a computer, which of course was a scam. Now he has to remove it from her computer and is going to format the PC and reinstall.

He's wondering how that scam may have affecter her passwords and data, however. Leo says there's no way to know. There could be a key logger on it that harvests all that information. Since she turned off the computer right away, there's a good chance they weren't able to get anything. If she had waited a few days or weeks to do anything about it, it could have logged all her activity.

Leo recommends Microsoft's Security Essentials, which is free.

Mike also noticed that his laptop has slowed down over time. Leo says that over time, Windows can suffer from "bit rot." The easiest way to fix it is to back up his data, then format the hard drive and restore the OS from the recovery disks to the way he got it when he bought it. Then he should make sure to run Windows updates.

Terry responded to a pop-up from someone who used remote access to get into his computer. Leo says that is a complete scam and it's likely that a they've infected his computer with viruses and maybe even key loggers to monitor activity on the computer. They even tried to charge him for this. Leo advises that he talk to a computer store in his area. Then have them backup his data and reinstall Windows. He can run a scanner such as the Microsoft Malicious Software Removal Tool by clicking Start, selecting "Run", typing MRT and hitting enter.

Leo says it's unlikely he has a virus, and it's more likely an email trick to get him to buy something with his phone. He should check his phone bill to be sure he hasn't been billed without him knowing it. He should reset the phone and be careful what he taps on!

Brandy's husband got bit by a computer virus called the SOPA Virus which has locked down their computer and says if they don't pay a fine, they'll get arrested. Leo says that's a lie and a very sophisticated one. This is ransomware and it's holding the computer ransom until they pay up.
