i think a trojan virus slowed my internet download speeds?

Question

hi. i was in the habit of turning off my AVG antivirus program to run games and then i forgot to turn it back on. anyway i ran an anti-spyware and found out i had a trojan downloader on my PC. then AVG said it found a trojan. so i ran complete scans and removed all the bad stuff. but now when i try to download files, my download speed is way way slower. like a server i could download 500 kb/s from is now about 100 kb/s. i tested on multiple sites and it is definitely way slower. i think the virus must have caused this somehow even though i removed it. what can i do?

Answer 1

Maybe not:

First, I suggest you run a full system antivirus scan using Safe Mode.

Then, check your PC for the following:

- Many users are not aware of how much RAM is used by wallpaper and/or a screensaver full of graphics. They run in the background and consume memory. (I have only 512mb RAM, run multiple programs simultaneously, and have set my wallpaper and screensaver to blank.)

I don’t do games, but I do know they are primarily graphics which need and use a lot of memory.

- How many programs do you load at startup? Maybe you should check it out and ensure you are running just what you need.
To do this: cl Start, cl Settings, cl Taskbar and Start Menu.
- cl Start Menu, cl Customize, cl Remove.
- cl the icon for the program you wish to remove
- then cl Remove.
- This will prevent the program from loading at startup, but will not remove the program from the hard disk.

- When you are working in a large file, save frequently to restore full memory access. (Your work remains in memory until you “save” it to disk.)

1. Did you run an error check? Open My Computer,
Right-cl on C:, Select Properties, Tools – Run an Error Check ( checkmark “check all and fix); then run a Defrag

2. Are you using Yahoo Toolbar? Run a full Norton Antispy.

3. From IE, click Tools, Internet Options
delete cookies
delete files (offline files)
clear history (set days to save to 0 if you want)
click o.k., and Restart

3. click Start, Programs, Accessories, System Tools – run Disk Cleanup

4. click Start, Run ipconfig renew (type ipconfig space renew)

All these things should be done regularly. The more frequently they are run, the less time they take.
- Note: Games and videos are mostly graphics. Graphics create large files. If this doesn’t help, you should consider getting more memory.

No anti-virus will sluggish your cyber web velocity down till that's doing updates which would be each 3 hours to a million day reckoning on your anti-virus application. that's needed which you save those automatic updates on because it is going to replace on viruses on the information superhighway so as that your application can hit upon, and get rid of it effectively. you're able to be questioning of the burden that anti-virus positioned on your laptop which makes your laptop slower. Avast seems to be like solid at not sucking up your laptop aspects even nevertheless it is not solid specifically circumstances. i take advantage of AVG and that i've got not had a virus get by my gadget considering that. I did a attempt to attempt to get viruses and that i carried out the main deadly movements on the laptop to get a virus and that i finished up with out any simply by fact of AVG. AVG is quiet as a mouse while it includes sucking up aspects and that's generic in each skill. i offered McAfee finished risk-free practices for $one hundred fifty AUD and that i've got been given some viruses in my laptop that McAfee detected yet I knew I nonetheless had extra to discover yet McAfee does not get them. I used AVG unfastened, remember, unfastened, and it chanced on over 2 hundred viruses. it is not a humorous tale, I experienced this. So i don't think that finding out to purchase some thing somewhat does provide you the final risk-free practices. the main universal your anti-virus, the main harder the viruses would be to hit upon simply by fact the virus can artwork it is way around common anti-virus application simply by fact's difficulty-free and used lots. desire this helped. i did not understand your question particularly nicely yet i attempted.
