If you suspect you have been infected with some kind of malware, there are several steps you must take. Unfortunately, if you find one infection, it is highly likely you have another one. A virus, trojan or worm are all different types of infections/malware.
First, clean up (delete) your cookies, temp files and temporary internet files. I prefer to use Ccleaner (available at www.filehippo.com) to do this, rather than the built-in DISK CLEANUP. If you want to use Disk Cleanup, you can find it if you:
- Double-Click on My Computer to open it up
- RIGHT-click on your C: drive
- Choose PROPERTIES and then click on the DISK CLEANUP button
- When done, reboot your computer.
Delete these files daily or run Ccleaner every day right before you shut your computer down.
2 - You should also have a good anti-virus program to help protect your computer. AVG FREE is an excellent anti-virus program, which can be downloaded from www.download.com.
3 -Since NONE of the anti-spyware/anti-adware programs are 100% accurate in finding and removing spyware, you need at least two programs which you will run one after the other, not at the same time.
There are three excellent free ones:
--Spybot, Search and Destroy
--Ad-Aware
--Spyware Blaster
All are available FREE from www.download.com
You will need to download, install, update (and IMMUNIZE in Spybot) and run them, one at a time. Be careful with the NAME of these programs - there are "look-alikes" with very similar names, that are in fact spyware themselves! Reboot after you install each one!
After this current infection is cleared up, be sure to run both of the above programs at least once a week if you are on the internet frequently and/or like to download music or files.
NOTE: Some infections prevent your from downloading the above programs. You may have to use a clean computer to download the programs and copy them to a thumb drive or CD. Then transfer the install files to the infected computer and run.
--Occasionally you will not be able to run these programs without being in SAFE MODE. To get there, reboot your computer and tap the F8 key, repeatedly until a menu comes up. You want to choose SAFE MODE WITH NETWORKING.
4 -You should also have a good firewall to help protect your computer. Zone Alarm makes a totally free version (watch you don't download the 30-day free trial of the paid version). You can download this from the manufacturer at www.zonelabs.com
HTH : )
Good luck!
