Well it had to happen sooner or later. I never had a problem with viruses
or spyware, but I spent most of yesterday eradicating them from my PC.
My PC was somehow infected late Saturday night. All of a sudden I was getting a pop-up ad about every minute, my browser home page was hijacked, and my Windows Media Player was inoperative due to a 'trojan horse' virus.
The Doctor is in the house!
The following is how I corrected the situation. I downloaded and ran...
Ad-Aware (SE) from Lavasoft. This software has various scan options for checking every file on your system for malicious or dangerous files
(spyware, malware, etc.). An On-Guard option takes more of a proactive approach
by running in real-time to catch malicious files BEFORE they enter your system.
Spybot SD (1.4). This is similar to Ad-Aware, but both products work a little differently, so it is best to run both of them.
Spyware Doctor. This is an amazing product that combines the functions of Ad-Aware and Spybot, and also has a real-time monitor to prevent annoying pop-up ads.
CWShredder. This software will search for the malicious Cool Web Search 'trojan horse' virus. My Windows Media Player would not operate
as it was infected by this (CWS) virus.
HiJackThis. This product will rectify problems caused by someone hijacking and controlling your browser home page.
Microsoft Anti Spyware. This is software that Microsoft released in a beta
version a few months ago.
All of the above, with the exception of Microsoft Anti Spyware, can be downloaded from either 'download.com' or 'majorgeeks.com'. It is all free, with the exception of Spyware Doctor, which has a 15-day free trial, then costs $30.
I recommend the following...
Run both Ad-Aware and Spybot, as they function a little differently, and will discover problems not detected in the other. This should be done on either a weekly or biweekly basis. The average run time of each is about 15 to 20 minutes.
Alternatively, you could run Spyware Doctor instead of (or even combined with) the above two, as it combines the functions of the other two. This also should be performed on a weekly or biweekly basis. Has the same
run time as the above two products.
Run CWShredder perhaps monthly, or whenever you experience serious problems in the operation of your Windows Media Player, browser or other
software. It only takes about one minute to run and destroy the CWS
virus.
Run HiJackThis if your browser home page is either corrupted or is replaced by another home page. This only takes a couple of minutes to run.
Run either the Ad-Aware On-Guard option or the Spy Doctor real-time
monitor to prevent malicious files from entering your system. This will also prevent pop-ups ads from occurring. I did notice a slight degradation in response time, but I suppose this is a small price to pay for 'protection'.
If you only have a few known pop-ups or malicious web sites, you can restrict them (various levels) in your browser by going to Tools, Internet Options, and Security. You can then enter the web site names in the Restricted Sites file.
Just a note regarding cookies...most are relatively harmless, but some can be malicious. They are data that is put on your computer by web sites
to aid them on future visits you make to their sites. Ad-Aware, Spybot
and Spyware Doctor will also flag malicious cookies. If you delete all of the flagged cookies, there's always the possibility of destroying some of the 'valid'/useful cookies. This is really not too serious, as it only means
you might have to enter a little more information the next time you
visit that web site.
I finally got my system back to 'normal' (well almost). I still have to do a little tweaking, as the software prevented an email attachment from
even loading. This is not good, as I like to determine myself on a case-by-case basis whether or not to open the attachment.
As I had never experienced any prior problems, I never had to run any of the above software, but once the problems start, they really are a pain and can cripple your PC. The scans that I ran on my system indicated that I had over 600 infected or malicious files!
I hope the above is helpful.
